2–3

DIRECT SERIAL (RS-232, RS-485) AND NETWORK CONNECTIONS

Note

CHAPTER 2: CONNECTING TO A GE METER

Port 1: Address 1, 57600 baud (first time connection, leave

Address set at 1)

Port 2: Address 1, 57600 baud (fixed Optical Port on EPM 9800)

Port 3: Address 1, 9600 baud (EPM 9450/9650 Only) (for External

Display or I/O Modules)

Port 4: Address 1, 57600 baud, Master/Slave (for External I/O

Modules)

You may use a connected External Display to view each port’s baud rate, address and communication protocol. See the meter’s Installation and Operation Manuals for details.

See Chapter 3 (EPM 9450/9650), Chapter 4 (EPM 9800) and Chapter 5 (EPM 4000, 5000,

6000, 7000 Series Meters) for details of how to configure the meter’s communication ports.

Z

In the Baud Rate field, enter a baud rate that matches the baud rate of the device’s port to which your computer is connected.

The port’s baud rate, address and protocol must always match the baud rate, address and protocol of the computer.

Z In the Serial Port field, enter the computer’s communication port into which the RS-232 cable is inserted.

Most computers use Com 1 or Com 2 for the serial port.

Z In the Protocol field, enter the type of communication the GE Meter port is using.

Direct Connections made through GE Communicator EXT must use either Modbus RTU or Modbus ASCII. Modbus RTU is recommended.

All meter port defaults are Modbus RTU and the meters are shipped set to Modbus RTU.

Z

In the Flow Control field, enter None or Hardware.

EPM setting should be None.

PM 6000 IrDA setting is Hardware.

Example: in the sample screen above, the computer’s Com Port 2 has been set to operate at 57600 baud, using Modbus RTU to communicate with a meter port located at address 1.

The baud rate, address and protocol set for the computer’s Com Port 2 match those of the meter port.

If the connection fails, make sure an approved Category 5 Cable is connected to the

Network Jack and that the Link Light on the GE Device is illuminated.

2.2.2

Network Connections

At the Remote (Meter) Location

SERIAL (RS-232, RS-485) MODEM CONNECTIONS CHAPTER 2: CONNECTING TO A GE METER

Note

Note

2.3

Serial (RS-232, RS-485) Modem Connections

For an RS-485 Internal Modem Option Connection see section 2.4 below.

Modem Connections Require Modbus ASCII Protocol.

The meter’s communication port that you use for the modem connection, must be configured to speak/listen to Modbus ASCII and operate at either 9600 baud or match the speed of the remote modem.

Modbus RTU does not support modem communication. If you use Modbus RTU to communicate with a modem, it will fail or be unreliable.

Note

2.3.1

Before Setting the General Configuration

Z Establish a direct RS-232 or RS-485 connection to the meter. (See section 2.2.)

Z After you have established a direct connection, refer to Chapter 3

(EPM 9450/9650) and Chapter 4 (EPM 9800) for details on how to configure the meter’s communication ports.

Z Set the port to Modbus ASCII at 9600 baud. (If you are connecting to multiple meters on a bus, you must also assign a unique address to each meter; see section 2.5.)

Z Install the modem connected to the computer (the “originate modem”) and the modem connected to the GE meter (the “remote modem”).

See the Installation and Operation Manuals for the meter(s) in use for details of the hardware requirements.

2.3.2

At the Remote (Meter) Site...

If you are using RS-232 communications without a Modem Manager:

Z Set the remote modem to operate at 9600 baud (remote and originating).

Z Disable Hardware Flow Control (remote and originating).

If you are using RS-485 Communication with a Modem Manager (recommended by

G.E.):

Z Set the baud rate for the meter higher (up to 38400).

Generally, it will provide reliable communication.

Z Enable Flow Control (remote and originating).

Because a GE meter’s four ports operate independently, you need only configure the address and baud rate of the port that will be connected to the bus.

CHAPTER 2: CONNECTING TO A GE METER RS-485 INTERNAL MODEM OPTION CONNECTION

Note

2.4

RS-485 Internal Modem Option Connection

Internal Modem Option Connection Requires Modbus ASCII Protocol.

Some meter models offer an Internal Modem Option, which eliminates all the modem hardware and cable that used to be required for a modem connection. A modem connection to the meter is now as simple as plugging in a phone line.

At the originate end, simply install a modem inside the computer (the originate modem) and connect a phone line. At the remote (meter) end, the meter must be configured to speak Modbus ASCII. (Modbus RTU does not support modem communication. If you use

Modbus RTU to communicate with a modem, it will fail or be unreliable.) The meter’s

Internal Modem Option may operate at a programmable baud rate up to 57600. We recommend this baud rate.

To set the overall configuration, you must:

Z Install the computer’s modem (the “originate modem”).

See the Installation and Operation Manual for the meter in use, for details of computer’s hardware requirements.

Z Set the originate modem to operate at 57600 baud

Z Enable Hardware Flow Control.

See Note about Baud Rate in Step 5 below.

2.4.1

At the Remote (Meter) site...

Z Plug a phone line into the meter.

The address will be 1. (If you are connecting to multiple units on a bus, you must also assign a unique address, other than 1, to each additional unit. See section 2.5.)

Because a GE meter’s four ports operate independently, you need only configure the address and baud rate of the port that will be connected to the bus.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 3–9

GENERAL SETTINGS CHAPTER 3: CONFIGURING THE EPM 9450/9650 METER installations. The standard Meter has the capability of very accurability monitoring 1A loads and providing extended current overload. This section shows how to change the CT

Ratios in the Meter (ONLY EPM 9450 Hardware Rev. A) to reflect the hardware change:

Standard 5 amp input

(one wind around internal meter toroid)

Modified 1-amp input

(5 winds around internal meter toroid)

In order to maintain maximum accuracy with one (1) amp current inputs, the wire is wound around the internal toroids five (5) times, instead of the usual one time. This effectively multiplies the current input by five (5) times, to maintain maximum resolution.

Configuring CT Ratios with Modification Number M10.0 (EPM 9450

Hardware Rev. A):

EPM 9650 (and other Hardware Revs) adjust internally for the hardware change.

Because the GE Communicator EXT “sees” the one (1) amp input as five (5) amps, it is necessary to configure the CT secondary to five (5) amps.

Example:

Normal One Amp CT Ratio - 1000:1

Meter M10.0 One Amp CT Ratio - 1000:5

The CT Ratio screen shows the correct input for the typical one amp user:

Purpose of Pulse Accumulations:

Pulse Accumulators are used to accumulate Pulse information from External Devices such as gas, water or electricity meters, energy management systems, SCADA devices or any pulse generating device. Pulse Accumulation is a very flexible way to accumulate information from external devices.

Pulses from other meters can be algebraically combined with the host meter’s pulse accumulations to generate one reading for a set of meters in a complex arrangement.

Source: This is the particular input on the meter which will be accumulated.

Units/Pulse: This is the scale factor which normalizes the pulses so that they can be aggregated, if desired. Pulses are stored in primary values.

Accumulator: This allows you to place the pulse register into a separate accumulation register, which can aggregate or net values.

User assigned label: This window allows a user to enter a label designation so that when reading the Aggregator, the meter will display the source.

Z To add or subtract data, use pull down menu in each window of

Accumulator column(s).

EPM 9450 does not support Averaging for Total Values that are NEGATIVE.

EPM 9650 DOES support that type of Averaging.

8 for how to view logs.

PQ and waveform thresholds are given as a percentage of the Full Scale (% of FS). Set the

Full Scale in the Limits and Waveform Full Scales section of the Device Profile (section 3.4).

Full Scales are based on the CT and PT ratios set in the CT, PT Ratios and System Hookup

Z Before programming the PQ and Waveform Thresholds, set the CT and PT ratios.

Z Set the Limits and Waveform Full Scales.

Caution: Changing the CT & PT Ratios will reset the meter and clear all Logs and Accumulations.

Note on Sampling Rate

A higher sampling rate allows for transients to be monitored. Generally, users will set the meter to 128 samples per cycle for this purpose. Lower sampling rates have advantages because they allow you to record more cycles of information per event screen. Low sampling rates are better for long duration events, like motor starts or distribution faults.

The meter enables users to tailor the recording for both these applications. For more information on Sampling Rate, see the graph later in this section.

Note on CBEMA

The CBEMA plotting is a power quality standard known world-wide for recording the amount of damage voltage transient conditions have done to the equipment being monitored. The meter automatically records this information.

For CBEMA purposes, the user programs internal set points for voltage below 90% and above 110% of full scale (+/- 10% from the nominal voltage). These setpoints are defined by the ITI (CBEMA) specification. The ITI (CBEMA) Curve is published by Information

Technology Industry Council (ITI) and is available at: http://www.itic.org/iss_pol/techdocs/ curve.pdf.

A user can set a recording with tighter voltage limits to trigger a waveform recording.

However, CBEMA plotting will be based only on the limits internally set.

Note on Setting the EPM 9450/9650 Meter to Record Current Faults

As discussed, the voltage setpoints are used to record voltage type events, such as voltage surges, sags and transients. The current settings are used to record faults on the line or inrush currents from devices such as motors.

Typically, to catch these events, set the limit to above 200% of full scale.

I A, B, C.

• If you select 512, a Capture Only pop-up screen will ask you to select one of the individual channels.

As you increase the number of samples, you will record more detailed information. The table below illustrates the “Effects of Sampling Rate” on the number of cycles captured.

Increasing Sampling Rate increases waveform definition but reduces the length of the observed window. The approximate length of the observed window is shown in the last column.

For example: For observed events of approximately 1/2 second, a sampling rate of 32 samples should be used.

One Amp Current Input Addendum (Modification Number M10.0)

For special circumstances, the Meter can be ordered with one amp current transformers.

This will give the Meter a range of 0 to 1 amps with an additional over-range of 1 amp.

This option is used where 1A IEC meters are required or extended low current performance is needed and higher current performance is not needed. This option is not used for most

1A installations. The standard Meter has the capability of very accurately monitoring 1A loads and providing extended current overload.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL

CHAPTER 4: CONFIGURING THE EPM 9800 METER GENERAL SETTINGS

The following shows the change made to the toroid to adjust for the modification.

Standard 5 amp input

(one wind around internal meter toroid)

Modified 1-amp input

(5 winds around internal meter toroid)

Note

In order to maintain maximum accuracy with one (1) amp current inputs, the wire is wound around the internal toroids five (5) times, instead of the usual one time. This effectively multiplies the current input by five (5) times, to maintain maximum resolution.

Z No modification is required to the CT Ratios because EPM 9800 CT

Ratios automatically adjust internally for this modification.

Use of the M10.0 Option is not recommended unless direct 1A IEC meter replacement of very extended low current performance is needed.

Purpose of Pulse Accumulations

Pulse Accumulators are used to accumulate pulse information from external devices.

These devices may be gas, water or electricity meters, energy management systems,

SCADA devices or any pulse-generating device. Pulse accumulation is a very flexible way to accumulate information from external devices. Using the meter’s pulse accumulator, pulses from other meters can be algabraically combined with the host meter’s accumulations to generate one reading for a set of meters in a complex arrangement.

Source: This is the particular input on the meter which will be accumulated.

Units/Pulse: This is the scale factor which normalizes the pulses so that they can be aggregated, if desired. Pulses are stored in primary values.

Accumulator: This allows you to place the pulse register into a separate accumulation register, which can aggregate or net values.

User assigned label: This window allows a user to enter a label designation so that when reading the Aggregator, the meter will display the source.

Z To add or subtract data, use pull down menu in each window of

PQ and waveform thresholds are given as a percentage of the Full Scales (% of FS). Set the

Full Scales in the Limits and Waveform Full Scales section of the Device Profile (section 4.4).

Full Scales are based on the CT and PT ratios set in the CT, PT Ratios and System Hookup.

Before programming the PQ and Waveform Thresholds, set the CT and PT ratios.

Then, set the Limits and Waveform Full Scales.

CAUTION: Changing the CT and PT Ratios will Reset the meter and clear all logs and accumulations. Be sure to capture needed meter information before changing CT and PT

Ratios.

Note on Sampling Rate

A higher sampling rate allows for transients to be monitored. Generally, users will set the monitor to 128 samples per cycle for this purpose. Lower sampling rates have advantages because they allow you to record more cycles of information per event screen. Low sampling rates are better for long duration events, like motor starts or distribution faults.

The meter enables users to tailor the recording for both these applications. For more information on Sampling Rate, see the graph on page 4-39.

Full Scales are shown in the lower right corner of the screen.

Note on CBEMA

The CBEMA plotting is a power quality standard known world-wide for recording the amount of damage voltage transient conditions have done to the equipment being monitored. The meter automatically records this information. For CBEMA purposes, the user programs internal set points for voltage below 90% and above 110% of full scale (+/- 10% from the nominal voltage). These setpoints are defined by the ITI

(CBEMA) specification. The ITI (CBEMA) Curve is published by Information Technology

Industry Council (ITI) and is available at:

http://www.itic.org/iss_pol/techdocs/curve.pdf.

A user can set a recording with tighter voltage limits to trigger a waveform recording.

However, CBEMA plotting will be based only on the limits internally set.

Note on Setting the Meter to Record Current Faults

As discussed, the voltage setpoints are used to record voltage type events, such as voltage surges, sags and transients. The current settings are used to record faults on the line or in-rush currents from devices such as motors. Typically, to catch these events, set the limit to above 200% of full scale.

Z To choose the Samples per Cycle to be recorded at 60 Hz, click on the Sampling Rate pull down menu.

Z Choose from 16, 32, 64, 128, 256 and 512 samples per cycle.

The number of samples per cycle you choose will inversely affect the number of cycles per capture.

• If you select 256, a Capture Only pop up screen will ask you to select Volts A, B, C or I A, B, C.

• If you select 512, a Capture Only pop up screen will ask you to select one of the individual channels.

As you increase the number of samples, you will record more detailed information. The

Table below illustrates the “Effects of Sampling Rate” on the number of cycles captured.

Increasing the Sampling Rate increases Waveform Definition but reduces the length of the observed window. The approximate length of the observed window is shown in the last column.

For example, to observe events of approximately 1/2 Second, a Sampling Rate of 32

Samples per Cycle or less should be used.

To remedy this problem, you can Enable the feature in View > Options > Log

Retrieval.

Z Click the Pad Meter Log File box in front of the feature.

Z Click OK.

This feature pads missing records for Log 1 and Log 2. The software causes the Log

Converter program to automatically pad the missing records with a value of 0 for each log retrieval process and stores them in the Log DB file.

By default, if the Meter Trending Interval is set for Greater than 1 Hour, the meter will always save a record on the hour in the Trending Logs.

System Components

The components of the Total Web Solutions© system are detailed below. Each component adds special features to this fully configurable system. For Flow Charts of the components see 6.10 to 6.12.

WebExplorer©: This component uses your Web Browser to provide you with direct access to all power data. Using your browser, you can access any data file, and because it looks like a standard HTML web page to an IT department, the data transmits through corporate firewalls. This fully configurable component allows you to customize your own SCADA quality web pages, graphics and configurations via FTP Server and/or FTP Client. The Main

Default Page is shown below. This is just an example; the web pages for your data may be changed or created to your own needs and specifications.

The URL address for this page is: http://www.myEPMmeter.com

6–2

WebXML©: A very versatile component for configuring data to your specifications. The data is polled, then stored in an XML file for later access by any client on the network. The data can be viewed via a host of applications including Internet Explorer and Microsoft

Excel, PowerPoint and Word.

WebReacher©: With this component, you can access meters anywhere in the world.

WebReacher© has a built-in Modbus data concentrator that allows you to poll up to 8 devices or 512 unique polling items from any device that uses Modbus RTU and/or Modbus

TCP protocols. WebReacher© can retrieve the data and consolidate it into web pages without separate software.

WebMod©: The 10/100BaseT design allows the unit to communicate using Modbus TCP.

Once the programmable network card is placed inside the meter, Port 2 becomes a gateway. The gateway enables a high-speed interface between the Network LAN and other Modbus-based IED (Intelligent Electronic Device) equipment. Modbus TCP is an industry-proven open protocol that can be easily integrated with other software or hardware.

HARDWARE CONNECTION CHAPTER 6: TOTAL WEB SOLUTIONS

6.3

Hardware Connection

The EPM 9450, 9650 and 9800 meters with the 10/100BaseT Ethernet Option (INP100) have all the components of the standard Meters PLUS the capability of connection to a network through an Ethernet LAN or to the Internet via Modbus TCP, HTTP, SMTP, FTP and/or DHCP.

Monitors with the 10BaseT Option (INP10) connect via Modbus TCP ONLY.

INP100 can auto detect the cable type and works with either straight or crossover cable.

INP10 does not have the straight connection capability.

Example: A direct connection between a PC and INP100 can use a straight or a crossover cable. But, for an INP10 connection, you must use a crossover cable.

EPM 9450/9650: RJ-45 Connection - Meter with 10/100BaseT Option to

Multiple PCs

The 10/100BaseT Option conforms to the IEEE 802.3 specification using unshielded twisted pair (UTP) wiring, allowing inexpensive RJ-45 connectors and CAT5 (or better) cabling to be used.

This LAN connection allows multiple PCs to be connected concurrently. The RJ-45 line is inserted into the RJ-45 Port on the face of the EPM 9450/9650 with 10/100BaseT option.

The connection using RJ-45 into the EPM 9450/9650 can connect the meter to a network using Modbus TCP protocol over the Ethernet. To connect with other meters using Modbus

RTU in either remote or local locations, you MUST use Port 2 (which is labeled Ethernet

Gateway) as a Master, and an RS-485 connection. The link using RS-485 is viable for up to

4000 feet (1219 meters).

RS-232: Insert RS-232 cable from a PC into Port 1 and set the Selector Switch to RS-232.

This connection is necessary in order to set the initial software configuration. For details on

EPM 9450/9650 connections and wiring, see the EPM 9450/9659 User’s Manual.

EPM 9800: RJ-45 Connection

The 10/100BaseT option conforms to the IEEE 802.3 specification using unshielded twisted pair (UTP) wiring. This allows the use of inexpensive RJ-45 connectors and CAT5 (or better) cabling. An RJ-45 connector is supplied with the meter.

This LAN connection allows multiple PCs to be connected concurrently. The RJ-45 line is inserted into the RJ-45 Port (or Jack) on the Port 3 cable coming from the back of the EPM

9800 with 10/100BaseT option.

The connection using RJ-45 into the EPM 9800 connects the meter to a network using

Modbus TCP protocol over the Ethernet. You can access the meter with a SCADA system,

MV90 and PCs all at the same time.

RS-232: Use the Optical Port on the face of the meter to make the RS-232 connection. The magnetic coupler snaps into place; the other end of the cable connects to your PC. This connection is necessary to set the initial software configuration. For additional details on

EPM 9800 connections and wiring, refer to the EPM 9800 User’s Manual.

CHAPTER 6: TOTAL WEB SOLUTIONS SETTING UP THE 10/100BASET CONNECTION

Note

6.5

Setting Up the 10/100BaseT Connection

Setting up the 10/100BaseT Option consists of configuring the web connection and the

Advanced Network Card Screens so that you can access the data you need from the Web.

Once the initial configuration is set, you will not need software, unless you want to make changes to the configuration. With the Basic Setup, you will be able to access the Default

Screens (page 6-1) that display a variety of Real-Time readings. You may wish to customize your screens. (See details in section 6.6.)

In order for the Web to access the data from a meter, the meter must have an IP Address.

An IP Address is a number (typically written as four numbers separated by periods, e.g.

107.3.2.54) which uniquely identifies a computer attached to the Internet. An IP Address can be assigned using a DHCP Server or it can be entered manually.

For your information, here is a brief explanation of DHCP:

DHCP (Dynamic Host Configuration Protocol) was created by IETF (Internet

Engineering Task Force) to enable individual computers on an IP network to extract their configurations from a server (the “DHCP Server”), or servers, that have no exact information about the individual computers until they request the information. The

DHCP Server “leases” the IP Address to the DHCP Client for a period of time from 15 minutes to a year. More information can be found in the Internet RFCs (Request for

Comments) regarding available servers and technical details.

In DHCP Mode, if a NACK message is received from the DHCP server, INP100 will stop all

Ethernet activities immediately and start a new DHCP process.

6.5.1

DHCP Setup

Enable the DHCP Mode in the meter:

Z From Device Profile in GE Communicator EXT, open the

Communication Ports screen.

Z Click on Advanced Settings.

Z Click DHCP tab.

Z Click Enable DHCP.

Z Access a working DHCP Server.

DHCP Servers automatically assign an IP Address and Subnet

Mask. Some DHCP Servers, such as the one in Windows 2000® allow you to assign a Default Gateway IP (DHCP Option #3), DNS

IP (DHCP Option #6) and SMTP Server IP (DHCP Option #69) to the meter. If your DHCP Server does not let you assign parameters other than the IP Address, enter those values manually.

Z Enter a unique computer name (Optional).

This allows the user to access the meter by name, if there is a

DNS Server working in conjunction with the DHCP Server. Please see your network administrator and the server’s user manuals

Block Password Protected Access

This feature blocks access to an EPM 9650 or 9800 at Modbus Address 1 in INP100/102.

The feature was added to INP100/102 runtime firmware in v0.1.52.

Note

Once it is enabled, the INP100/102 network card will block all network requests when it detects that a user is sending a password to the meter at Modbus Address 1.

As a result, if the meter is password-enabled and the user is trying to gain access by sending a password through the network interface via Modbus TCP or through the modem via Modbus ASCII, the operation will be stopped and the user will not be able to access the password enabled area.

Use of this feature requires an INP100/102 firmware update and a GE Communicator EXT software update.

Update Procedures:

Z Go to the meter’s /update1.htm page to update its firmware.

(Example: 100.0.0.0/update1.htm)

FTP Client Settings Example:

By default, Microsoft’s FTP Server will use “C:\Inetpub\ftproot\” as the root directory. When a user logs onto the FTP Server, this is the initial directory the user will see.

1.

If the files for INP100 are stored in the root directory (“C:\Inetpub\ftproot\”), leave the

“Startup Remote Directory” text box empty.

Example Files in FTP Server’s Root Directory:

C:\Inetpub\ftproot\index.htm

C:\Inetpub\ftproot\poll_profile.xml

C:\Inetpub\ftproot\logo.gif When INP100 starts up, it will check to see what files are in the server’s directory and will download them all.

2.

If the files for INP100 are stored in a subdirectory in the root directory, such as

C:\Inetpub\ftproot\EPM_meters\feeder_12345\, put EPM_meters/feeder_12345 in the Startup Remote Directory text box.

Note the different “/” between directory names.

When INP100 starts up, it will check for all files in the server’s directory (EPM_meters/

feeder_12345) and download all files found.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 6–17

SETTING UP THE 10/100BASET CONNECTION CHAPTER 6: TOTAL WEB SOLUTIONS

If there is another subdirectory inside this directory that is not listed in the server’s directory as above, such as “C:\Inetpub\ftproot\EPM_meters\feeder_12345\info\”,

INP100 will not locate that subdirectory and no files will be downloaded from that subdirectory to INP100.

That may cause an error during the file downloading process and the system may not enter its normal operation mode until the subdirectory is removed from the server.

3.

The user should always check the FTP server to see if it’s configured properly. To do this, open the IE browser window, enter the correct address in the URL window.

The standard format is: ftp://[username]:[password]@[ip_address].

Example:

ftp://john:[email protected] where John is the user name and 1a2b3c is the password.

INP 102 Ethernet/Modem Combination

INP 102 is an extension of INP 100. It has all the features of an INP 100, plus a built-in modem. The communication protocol supported by the modem is Modbus ASCII. The communication protocol supported by the RS-485 Ethernet/Modem gateway port is

Modbus RTU.

The INP 102 converts all Modbus ASCII incoming modem requests to Modbus RTU for internal and gateway communication, then it converts all response Modbus RTU messages into Modbus ASCII protocol and send out to the modem. Some of the fixed parameters for the Ethernet/Modem gateway port are: 8 data bits, no parity, 1 stop bit. The Ethernet/

Modem gateway port's baud rate and delay time are configurable.

The modem has three operational modes:

1.

Modem Command

Mode Invisible to users. Modem is idle, waiting for incoming call.

2.

User Command Mode

Visible to users. If modem password protection is enabled, the user can enter the password in this mode, so that the modem can grant him access. In addition, the user can query the modem for its boot and runtime firmware version, modem identification information.

3.

Passthrough Mode

Normal Operation mode. Modbus requests and responses are passed through the modem.

DNP for LAN/WAN

The original DNP 3.0 was designed for serial point-to-point communication (e.g. RS-232) with limited support for half-duplex serial networks (e.g. RS-485). In order for devices to exchange DNP messages in a local (LAN) or wide area network (WAN), one must either augment the protocol to support a network environment or use an existing network transport mechanism. DNP 3.0 LAN/WAN was specifically defined to transport DNP traffic on the Internet Protocol Suite.

GE’s DNP 3.0 LAN/WAN implementation was based on the specifications described in

DNP3 Specification, Volume 7, Networking, according to the Version 2.0 Draft E of March 12,

2004. The official DNP 3.0 specifications can be found at www.dnp.org.

GE's DNP 3.0 LAN/WAN feature is available for certain EPM advanced meters with INP-100/

102 Network Card. Currently, advanced power meters with INP-100/102 have this feature.

If a user chooses to use this feature, the user has to configure the EPM meter's DNP

Custom Classes Map in the meter's Device Profile. See Chapter 4 of this manual for configuration screens and details.

Modes of Operation

Disabled: Feature is disabled. No DNP 3.0 LAN/WAN communication will be accepted.

Standard: Feature is enabled. Most communication parameters are fixed, except the port number to which UDP packets respond. Security features are not available.

Manual: Feature is enabled. All communication parameters are configurable. Security features are available.

A single DNP Over TCP connection and a single DNP Over UDP connection will be available when it is enabled. While DNP Over TCP connections may be closed at the decision of the network card, the main meter might also determine that the current DNP Over TCP connection should be closed.

Since INP-100/102 has several built-in servers, the DNP LAN/WAN TCP and UDP Listen on

Ports defined by the user cannot be one of the following:

Example of setting up validation for IP Addresses

1.

Set Validate Source IPs to 1 IP Address.

2.

Set Validate Source ports to Yes.

3.

Enter IP address, such as 10.0.0.101.

4.

Enter mask, such as 255.255.255.128.

5.

Enter TCP ports range, such as 20000-20000.

6–22 GE COMMUNICATOR EXT – INSTRUCTION MANUAL

CHAPTER 6: TOTAL WEB SOLUTIONS SETTING UP THE 10/100BASET CONNECTION

6.

Enter UDP ports range, such as 20000-20000.

As a result, a valid DNP 3.0 LAN/WAN request must come from a device with IP address of

10.0.0.1 to 10.0.0.127, with TCP and UDP ports set at 20000.

If a DNP Over TCP connection was established and Validation was also enabled, any new incoming DNP Over UDP connection has the same IP Address as the TCP connection. If they are different, the UDP connection will be closed.

The DNP address in the DNP LAN/WAN request should always be 1. All incoming communication for DNP LAN/WAN will go to the main meter and no DNP communication will go to the INP-100/102's gateway port.

Configuring WebXML©

The term XML stands for EXtensible Markup Language. XML is a markup language similar to HTML which is used to describe data.

HTML displays the data. XML does not replace HTML; it compliments HTML.

An XML document is information wrapped in XML tags. A piece of software has to be written to send, receive or display the document.

The “Rules” of XML

1.

The first line of the document, the XML declaration, defines the XML version and the characters used in the document.

2.

All XML elements MUST have a closing tag. It is illegal to omit the closing tag.

3.

XML tags are case sensitive.

4.

All XML elements must be properly nested.

5.

All XML documents must have a root tag (first tag in an XML document).

GE COMMUNICATOR EXT – INSTRUCTION MANUAL

CHAPTER 6: TOTAL WEB SOLUTIONS CUSTOMIZING SCREENS

6.

Attribute values must always be quoted. It is illegal to omit quotation marks around attribute values.

7.

Comment syntax is similar to HTML. <!--This is a comment-->

Example of Root Tag and Elements:

The first tag in an XML document is the root tag. All XML documents must contain a single tag pair to define the root element. All other elements must be nested within the root element.

All elements can have subelements ("children"). Subelements must be correctly nested within their parent elements as shown below:

<root>

<child>

<subchild>.....</subchild>

</child>

</root>

Example of Attributes:

<data id=”1” value=”123”></data>

6.6.3

Configuring WebReacher©

Through the configuration of poll_profile.xml, you can poll up to 8 individual devices or up to 512 unique items via Modbus RTU protocol or Modbus TCP protocol.

Devices supported: Any device that supports Modbus RTU or Modbus TCP protocol (with at least one available socket).

Devices supported for Advanced Features: EPM 9450/9650 and EPM 9800. (Use Generic

Modbus device settings for EPM 4000, 5000, 6000, 7000 meters.)

System set-up: Set DATA_POLL_DELAY in milliseconds; the system will pause between each

Modbus poll. Set SYSTEM_COMM_TIMEOUT in milliseconds.

Z Assign a protocol, DEV_PROTOCOL

Z Assign user defined device name, DEV_NAME (should be unique in a system).

Z Assign Modbus device address, DEV_ADDRESS.

Z If protocol is Modbus TCP, assign the remote device’s IP address and the TCP port number, DEV_IP and DEV_TCP_PORT.

Z Set max Modbus packet length in number of registers,

DEV_MAX_PACKET_LEN.

6–36 GE COMMUNICATOR EXT – INSTRUCTION MANUAL

CHAPTER 6: TOTAL WEB SOLUTIONS CUSTOMIZING SCREENS

Z Set device’s communication timeout in milliseconds,

DEV_COMM_TIMEOUT.

The timeout value should be longer for devices that speak Modbus

TCP than for devices that speak Modbus RTU, depending on network traffic.

Z Set device’s data display format, DEV_DATA_FORMAT, from 0 to

0.000000.

Z You can expand the polling item limitation of 64 items per device by setting a device as a child device of a parent device.

For example, in <DEVICE_X> section, if you set it to be the parent device, DEV_PARENT must be X or 0. Then for <DEVICE_Y>section, if you set the device to be a child device of X, set

DEV_PARENT to X. Other parameters can be omitted.

Common Problem

If you entered a name for the SMTP Server instead of an IP Address, make sure your DNS

Server is working and you have either set a DSP IP inside the meter or your DNS can supply a DNS IP. Otherwise, if it cannot resolve the name to an IP translation; no email will be sent.

Stored Emails

User can access the stored_emails.htm page from any internet browser. The last 10 emails sent will be stored in the RAM on a FIFO basis (First In, First Out) and will be displayed in descending order. The page will be cleared after a complete system restart.

FTP Server

FTP SERVER

A built-in FTP Server is available for INP100. It has a 3-user limit; three users can connect to the FTP Server simultaneously. The FTP Server logon User Name and Password are stored in the INP100 card, not in the meter’s programmable settings. The Initial FTP Server User

Name and Password are: GE Multilinnet and inp100. The FTP Server’s quota is 4Meg RAM.

To change the Initial FTP User Name and Password, switch to INP100’s boot mode and change the Initial Settings. (See section 6.9.)

To copy a file into the FTP Server, simply copy the file and paste it into the Server. If there is a file with the same file name in the Server, you must delete the existing file first, then copy and paste the new file.

If the memory quota is filled before a new file is completely copied into the FTP Server, that file will be deleted and an error will be sent to the FTP Client.

Since poll_profile.xml and poll_data.xml file sizes can be dynamic, it’s preferable to have some reserved space in the FTP Server for those files.

Example: After a test run, if poll_data.xml is approximately 1kB, you should reserve at least 4kB for those files. The ratio is about 1 to 4.

Chapter 8: Viewing Logs

Viewing Logs

8.1

Overview

The EPM 9450/9650 and EPM 9800 Meters record the following logs (EPM 7000 logs as noted):

Historical Trends Logs 1 and 2 (EPM 7000 - Historical Log)

These logs are two separate collections of time-stamped records (or “snapshots”) used to track any parameter over time. Each record or snapshot can contain multiple data items, which are recorded at specific intervals and stamped with the time of recording. The following programmable criteria determine when the Meter will take a snapshot:

The user-specified time interval

A parameter’s exceeding of a limit or a return to within limits

The capture of a waveform

An I/O event (a change in a relay or input)

Limits Log

The Limits Log retrieves independent out-of-limit information, creating a sequence of events for any occurrence.

Event-Triggered Waveform Log (EPM 7000 Series)

The Event-Triggered Waveform log records a waveform when a user-programmable value goes out of limit and when the value returns to normal. All information is timestamped to the nearest 1 msec. A new feature for interharmonic analysis observes further frequencies.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 8–1

OVERVIEW

8–2

CHAPTER 8: VIEWING LOGS

Power Quality (CBEMA) Log

This log records magnitude and duration of voltage and current surges and sags for every power quality (PQ) event. The associated waveform is also recorded.

Status Change (Input) Log

(Included in EPM 7000 Series Event I/O Log)

This log displays the input change status for a selected meter file and time range.

Control Output (Relay) Log

(Included in EPM 7000 Series Event I/O Log)

This log displays the relay change status for a selected meter file and time range.

AiReports

AiReports 2.0 is an optional power quality analysis software package used in conjunction with meter Logs. It provides a comprehensive report on the status of the equipment being monitored; it uses artificial intelligence to diagnose PQ events and provide the possible cause of the event.

System Events Log

The log records system events for security and anti-tampering.

The following is the general sequence for working with all logs:

1.

Program parameters specific to each log in the meter’s Device Profile (section

8.2). Logs run automatically.

2.

Retrieve the logs manually from the meter (section 8.3); or retrieve logs automatically using the Script & Scheduler Program. See Chapter 15 for further details.

3.

View and analyze log data with GE Communicator EXT’s Log Viewer (sections

8.5–8.18).

4.

Diagnose PQ Events from meter logs, create comprehensive report, transmit, modify, print or export file with optional AiReports software (section 8.15).

Free Space Calculation Feature

The Log Converter automatically checks your computer and calculates the amount of free space on your hard drive. This calculation is performed to insure enough hard drive space for the Log Converter to operate. Below are the parameters for the calculations and the actual calculation performed by the meter.

Programming and Running Logs

Program the following parameters specific to each type of log in the meter’s Device

Profile. See Chapter 3 (9450/9650), Chapter 4 (9800) or Chapter 5 (7000) for details.

Any time you update the Device Profile, a pop-up screen will announce that the logs are not being reset and asks if you would like to reset them. Resetting the logs is recommended if you make changes to CT & PT Ratios, Limits or Limit Full Scales.

• Limit and Waveform Full Scales

• Limits

• Trending Setup

• Trending Log Time Intervals

• Power Quality and Waveform Thresholds

• Labels — YOU MUST LABEL THE METER

You do not need to start the logs; the meter is always recording.

,

IEC-1000-2-1 [1] defines Interharmonics as follows: “Between the harmonics of the power frequency voltage and current, further frequencies can be observed which are not an integer multiple of the fundamental. They can appear as discrete frequencies or as a wideband spectrum.”

To perform the analysis, there must be a waveform record with a 200ms duration. For a

50Hz system, the waveform is 10 cycles; for a 60Hz system, the waveform is 12 cycles. By default, the starting point for Interharmonic Analysis of a Waveform is its first point. But, a user can set a starting point (place the mark) anywhere in the waveform, assuming that there will be enough sample points available after the starting point. If there are not enough points in this waveform capture, the software will check the next waveform record(s) stored in the database. If it is contiguous, additional points up to 200ms will be retrieved for analysis. For a waveform with sampling rate equal to or less than 64, the software will only check the next (1) contiguous record. For a waveform with a sampling rate equal to or greater than 128, the software will check the next two contiguous records.

Resetting the mark will set the starting point back to the waveform’s first point.

Z From the detailed view of the graph from the main Waveform screen, click the Interharmonic Analysis button.

The following screen will appear.

Measurement

IEC 61000-4-7 ([ref] First Edition) establishes a well disciplined measurement method for harmonics which utilizes 10 (50Hz systems) or 12 cycle (60Hz systems) sample windows upon which to perform the Fourier transform. The result is a spectrum with 5Hz resolution for both 50Hz and 60Hz systems. The standard further defines ways of combining individual 5 Hz bins to produce various groupings and components for referenced limits and guidelines.

The IEC Measurement Method defines interharmonic groups. These indices are the RMS values of the interharmonic components between adjacent harmonic components. The frequency bins directly adjacent to the harmonic bins are omitted. This relationship is defined by the following equation:

CHAPTER 8: VIEWING LOGS COMTRADE CONVERTER

Note

8.16 COMTRADE Converter

The latest release of AiReports includes a new useful feature: COMTRADE Converter.

Common Format for Transient Data Exchange (COMTRADE) is a standard that defines a format for the files containing transient waveform and event data collected from power systems or power system models. The format is intended to provide an easily interpretable form for use in exchanging data. As such, it does not make use of the economies available from data encoding and compression that proprietary formats depend upon for competitive advantage.

The standard is for files stored on physical media, such as digital hard drives and diskettes.

It is not a standard for transferring data files over communication networks. This standard defines a common format for the data files and an exchange medium needed for the interchange of various types of fault, test and simulation data.

The COMTRADE Converter carefully adheres to COMTRADE specification IEC 60255-24

(2001).

File types and operations

COMTRADE converter will generate the following types of file: filename.cfg filename.dat filename.inf filename.d## filename_*.cfg filename_*.dat filename_*.inf filename_*.d##

The term filename represents the user specified file name.

The symbol ## represents a value from '00' through '99'.

The symbol * is the number of 1 or above for each additional waveform record.

File type cfg is for Configuration.

File type dat is for Data.

File type inf is for Information.

The software requires user to enter a unique filename each time the COMTRADE converter runs. Upon COMTRADE Converter startup, it will scan all files with the filename provided by the user at a location associated with COMTRADE (file types listed above). If it finds any file that already exists, the software will issue a message and no conversion will take place.

The software will not overwrite an existing file; it will only convert to a new filename.

Stage 1: The change relay state process starts.

Stage 2: A meter responds to the change relay request and sends out the change relay command to the relay device.

Stage 3: The meter gets a response back from the relay device.

A complete record should have all three stages’ date/time stamp. The Start State is the relay state at the time of the Trigger. The End State is the relay state at Stage 3 or the

Acknowledgement Stage.

Reasons for Incomplete Records

• At the time of the log conversion process, if the Log Converter cannot find the

Stage 1 record (which can be caused by log roll over), the Trigger date/time and the

Start State will not be displayed.

• At the time of log conversion, if the Log Converter cannot find the Stage 1 record, the Inputs, Gates and the Relay Start State will not be displayed.

OUTLINE OF THE PROCEDURE FOR INSTALLING I/O MODULES CHAPTER 10: EXTERNAL I/O MODULES

Note

10.2 Outline of the Procedure for Installing I/O Modules

The steps below are detailed in subsequent sections of this chapter.

Z Review I/O hardware details in the meter’s Installation and

Operation Manuals.

Z Before connecting any I/Os to the EPM Meter, make sure each one has its own unique address.

All I/Os are shipped with a pre-set address and a baud rate of

57600. See section 11.5 for a list of factory-set addresses and baud rates. To assign or change I/O addresses, see section 11.6.

Z Write down the name and unique address of each I/O you will be using. (You will need to know the addresses for the EPM Meter’s

Device Profile.)

Z Connect the I/O or group of I/Os to the EPM9450/9650 Meter’s Port

3 or 4 or EPM 9800 Meter’s Port 4.

• You must use the correct port. Be sure ports are set to operate at the same baud rate as the I/O modules.

• The ports must also be configured as Masters. See Chapters 3

(EPM 9450/9650) and 4 (EPM 9800) for how to configure the communication ports.

Z Retrieve the EPM Meter’s Device Profile.

• In the External Devices section, enter the name of each I/O and its unique address.

• Use the Edit buttons to configure the I/Os.

• Each I/O connected to the unit must be included in the Device

Profile.

• Update the Device Profile to record the changes. See section

11.7.

Updating the Device Profile will reset all logs.

This chapter also covers the following I/O utilities:

Meter I/O Device Status (section 11.13): lists all registered I/Os currently in use.

Query I/O Module (section 11.14): locates an I/O’s address and baud rate.

Locator Utility (section 11.15–16): locates an I/O’s address and baud rate without using the reset button.

Stand Alone Programmer (section 11.17): allows you to configure all I/O parameters directly from a computer, not through a EPM Meter.

CHAPTER 10: EXTERNAL I/O MODULES USING MULTIPLE I/O MODULES

10.3 Using Multiple I/O Modules

Each type of I/O module is shipped with a factory-set address (see section 11.5). If you plan to use more than one I/O module of the same type (such as three KYZ modules), you must change the address of each module individually before connecting the group to the EPM

Meter. See section 11.6 for how to change a module’s address and baud rate.

Each I/O module in a group must have its own unique address. Each module must be set to operate at the same baud rate as the EPM 9450/9650 Meter’s Port 3 or Port 4 (Port 4 ONLY for EPM 9800) (57600 is recommended).

If you do not know an I/O module’s address or baud rate, use the Query I/O function detailed in section 11.14. This function works only on Port 4.

To connect multiple I/Os together, attach the male RS-485 port of one module to the female RS-485 port of another. Secure by tightening built-in fasteners. Attach mounting brackets to the outside modules. Use the steps below (section 11.4) to determine if you must use a separate power source (for example, GE Multilin PSIO) to supply added power to the group.

To connect a group of I/Os to the EPM Meter, connect an RS-485 cable to the group’s available female RS-485 port. Connect the other end of the cable to the EPM 9450/9650

Meter’s Port 3 or 4 (Port 4 ONLY for EPM 9800).

You may combine different types of I/O modules together in a group.

After all modules have been assigned a unique address and connected to the EPM Meter, you must enter them in the EPM Meter’s Device Profile. See section 11.7.

Chapter 11: Passwords

Passwords

Note

11.1 Overview

The use of the Password feature is recommended ONLY if there are security issues and

ONLY if you have a secure place in which to save the password. If you have forgotten your meter password, you cannot call the factory for help. There is no “back door”. If you lose or forget your password, you must send the unit back to the factory to have the Flash

RAM that stores the password replaced.

If you are not using this meter for primary revenue metering or for protective functions, you do not need to put a password protection scheme in the unit. If you do, make sure you archive the meter location and associated passwords carefully!

GE Communicator EXT’s password feature protects the following from unauthorized use:

• Changes to an GE Meter’s Device Profile

• Setting Meter Time

• Resetting Meter Information (Max/Min/Demand, Hour Counters, Logs and Time-of-

Use)

• Test Mode Entry from software

• Flash Upgrades

• Flicker Start and Stop

• Pulse Test

• CT and PT Compensation

• Relay Control and I/O Utilities

• Time-of-Use Accumulations and changes to the Time-of-Use calendar settings

Password protection has two levels:

• Level 1 accesses Time-of-Use Accumulations Only. These are billing functions.

• Level 2 accesses all password-protected functions (listed above). The Level 2

Password also allows a user to enable or disable the password function.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 11–1

OVERVIEW CHAPTER 11: PASSWORDS

When the password feature is enabled, GE Communicator EXT will ask for the appropriate password each time a user attempts to perform a protected operation.

The password feature is on a two-minute timer: after exiting from a password-protected area, the user has two minutes to access another protected area without re-entering the password. If more than two-minutes elapse, GE Communicator EXT will ask for the appropriate password. Use the Log On/Off feature (section 12.4) to renew password protection immediately.

Chapter 13: Energy Billing Module

Energy Billing Module

13.1 Overview

13.1.1 Managing Your Load Profile

Your monthly electric bill is composed of your total energy usage (kWh) plus your maximum demand (kW) during the billing period. Maximum demand, (a.k.a. peak demand), can represent 30% to 60% of your total energy cost. Managing your load profile is the key to reducing your costs; reducing your peak demand, even without changing your total usage, lowers your costs.

The optimal load profile would be flat, with minimum demand at constant usage. But, a flat load profile is not possible in industrial and commercial environments because of the variation and number of loads in the system. However, there are steps you can take to control those variations and ultimately reduce costs. The steps are listed below:

• Collect historical and real time energy data.

• Use graphical tools to calculate and analyze the data.

• Control loads and shift the timing of demands.

• Calculate savings and results.

The Energy Billing Module detailed in this chapter gives you a tool to use with the EPM

9450, 9650 and 9800 meters to collect data and analyze it. With a few clicks, you can collect historical and real time power usage data so that you can make changes necessary to reduce costs.

CHAPTER 13: ENERGY BILLING MODULE BASIC ENERGY MANAGEMENT

13.2 Basic Energy Management

To understand how to manage your power usage, you must understand billing determinants and the terminology of energy management. Below are Basic Energy Terms followed by an Energy Management Example.

13.2.1 Basic Energy Terms

Kilowatt hour (kWh)

Kilovolt-ampere-reactive hour

(kVARh)

Megawatt-hour (MWh)

Energy (Active and Reactive)

Interval Type

Demand

Load Factor

Block Demand

Rolling (Sliding) Demand

Window

Measurement for energy equal to the amount of work done by 1,000 watts for one hour.

Measurement similar to kWh that reflects current drawn by a customer that produces no useful work, but takes up space on the electrical distribution system.

1,000 kWh.

The total consumption that is measured in Kilowatt hours (kWh) and Kilovolt-ampere-reactive hours

(kVARh).

An interval is composed of N subintervals

(1<=N<=10). The data collected in the previous N subintervals is used in the demand calculation.

Rate at which electric energy is delivered to a system, usually expressed in kW or MW. There are two methods for calculating demand: (1) Block window and (2) Rolling (or sliding) window.

An indicator of the quality of the load profile (0 to 1) for a certain period in the electrical system.

Demand calculations performed over a fixed period

(interval) of time. When that time period lapses, the next interval starts where the previous interval ended.

Demand calculations performed over a fixed period

(interval) of time that is made up of (n) subintervals

(n=>2). When one subinterval elapses, the demand value is computed by adding the most recently completed subinterval data to the demand interval and subtracting the oldest subinterval data from the demand interval.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 13–3

BASIC ENERGY MANAGEMENT CHAPTER 13: ENERGY BILLING MODULE

Thermal Demand

Power Factor

Time of Day or Time of Use

Off-Peak

On-Peak

Shoulder

Real Time Pricing

Aggregation

Emulation of a Thermal Demand Meter that provides an exponentially time-lagged demand where, given a constant load, the indication reads

90% of the actual demand in 15 minutes.

An indicator of the quality of the power (-1 to +1) at a certain point in the electrical system.

Rates vary at different times of the day (on-peak and off-peak) for Energy and Demand.

Designated periods of low system demand (usually non-business hours) when electricity is generally less expensive.

Designated periods of high system demand when electricity is generally more expensive.

Designated periods between off-peak and on-peak.

The instantaneous pricing of electricity based on the cost of the electricity available for use at the time the electricity is demanded by the customer.

Rates are downloaded over the phone or Internet.

This is a customized plan.

The combined total energy use of customers/ units/ cost centers for billing purposes.

Energy Management Example:

A light manufacturer operates on two shifts. The typical electricity cost is about $150,000 per year. Before the installation of any energy management equipment and software, the facility was paying, in a typical summer month, $12,000 for electricity.

56,000 kWh (Off-Peak) - $2,400

120,000 kWh (On-Peak) - $5,500

480 kW (Peak Demand) - $4,100

Total Bill - $12,000

13–4 GE COMMUNICATOR EXT – INSTRUCTION MANUAL

CHAPTER 13: ENERGY BILLING MODULE BASIC ENERGY MANAGEMENT

FIGURE 13–2: Energy Management Example - Before

With the Energy Billing Module, plant management is able to optimize the loads. Essential loads are monitored and turned on or off in sequence. Simple steps are taken without jeopardizing the integrity of the manufacturing process. Savings in energy costs = 4% (see calculations above and below).

56,000 kWh (Off-Peak) - $2,400

120,000 kWh (On-Peak) - $5,500

480 kW (Peak Demand) - $3,600

Total Bill $11,500

FIGURE 13–3: Energy Management Example - After

Further savings can be realized by doing the following:

• Shift non-essential loads to off-peak hours.

• Flatten the demand curve wherever possible.

• Identify equipment and process problems.

• Negotiate with your utility based on peak demand.

• Source the best utility for your needs.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 13–5

COST ALLOCATION CHAPTER 13: ENERGY BILLING MODULE

13.3 Cost Allocation

In addition to the cost savings steps listed above, further steps can be taken using Cost

Allocation. By submetering , one of your primary fixed costs, electricity, becomes a variable cost that can be accurately allocated.

13.3.1 Cost Allocation Steps

• Determine cost centers.

• Use submeters to monitor usage at each cost center.

• Assign accountability and offer incentives for departments within a facility to reduce their own energy usage.

• Determine equipment and system efficiency within cost centers.

• Make sure Tenant Billing accurately reflects usage.

13.3.2 Cost Allocation System

• One computer at primary facility.

• A number of low cost, high quality meters to monitor usage at each cost center. •

A simple network connecting the meters to the computer.

• Energy Billing Module.

OPERATIONAL OVERVIEW CHAPTER 14: SCRIPT & SCHEDULER PROGRAM

Note

Note

14.2 Operational Overview

The user creates the scripts with the software, adding devices and commands, and sets up the Scheduler. Once this is accomplished, the Scheduler runs automatically, executing the script with the oldest scheduled run time first.

When the script is run by the Scheduler, small windows appear on your PC to advise you that the script is running and data switch strings (if needed) and commands are being sent. A new scheduled run time is calculated. If the Frequency Type is “Once”, this script will be removed from the Scheduler immediately. Any failures to connect or complete commands will be noted in the Scheduler log (see Process Log below). A multiple page

Script Report will be generated when a user selects a script from the list box and clicks the

Report button.

After GE Communicator EXT finishes the script, the Scheduler starts the Log Converter

Manager to convert the binary logs to Microsoft Access format. The Scheduler automatically launches the Log Converter program which converts the log files one at a time to a database file after a download has succeeded.

After the Log Converter Manager finishes its conversion, the Scheduler can resume its process and run the next script with the oldest run time. If there are no files to convert, the screen will appear as above.

Log Converter: The log converter’s purpose is to convert the binary data accumulated from the GE device into the ODBC compliant (Access) database for later retrieval. This is done automatically within the software.

Devices: The GE Script & Scheduler can be used with many GE devices, including EPM9450/

9650, EPM9800 and Series 7000 meters. The Scheduler Log can be viewed by clicking View

Log on the main Scheduler screen. The script logs produced by the Scheduler can be found in Drive:\ Program Files\ GE \ Communicator\ Retrieve\ Logs. The files produced by the

Log Converter program can be accessed in Drive:\ Program Files\ GE \ Communicator

EXT in a default subdirectory.

GE Script and Scheduler has a new Process Log, which is in HTML format and carries the

.HTML extension. The Process Log consists of three top level files that work together to signal an error and provide links to detailed script logs and detailed log converter logs.

Following are the files that make up the Process Log:

EPMSchedulerLog - Main.Html: Software generated top layer file with frame set linked to EPMSchedulerLog - Detail.Html and EPMSchedulerRun-TimeLog.Html.

EPMSchedulerLog - Detail.Html: Software generated blank frame file.

EPMSchedulerRun - TimeLog.Html: Software generated schedule process log with hypertext link to detailed script logs and detailed Log Converter logs.

If any type of error occurs during the execution of a scheduled script, EPMSchedulerRun-

Time Log.Html will have an entry in red with the appropriate hypertext link to its detailed logs. The Reset Alarm button will also create a visual alarm (red background color) and a continuous beep (until the user clears it), if an error occurs. To clear the contents of a current EPMSchedulerRun-TimeLog.Html file, the user deletes that file from its location.

Chapter 15: Flicker

Flicker

15.1 Overview

Flicker is the sensation that is experienced by the human visual system when it is subjected to changes occurring in the illumination intensity of light sources. The primary effects of flicker are headaches, irritability and sometimes epilepsy.

IEC 61000-4-15 and former IEC 868 describe the methods used to determine flicker severity. This phenomenon is strictly related to the sensitivity and the reaction of individuals. It can only be studied on a statistical basis by setting up suitable experiments among people.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 15–1

THEORY OF OPERATION CHAPTER 15: FLICKER

15.2 Theory of Operation

Flicker can be caused by voltage variations which are caused by variable loads, such as arc furnaces, laser printers and microwave ovens. In order to model the eye brain change, which is a complex physiological process, the signal from the power network has to be processed while conforming with Figure 16.1 below.

Block 1 consists of scaling circuitry and an automatic gain control function that normalizes input voltages to Blocks 2, 3 and 4. For the specified 50 Hz operation, the voltage standard is 230 V RMS.

Block 2 recovers the voltage fluctuation by squaring the input voltage scaled to the reference level. This simulates the behavior of a lamp.

Block 3 is composed of a cascade of two filters and a measuring range selector. In this implementation, a log classifier covers the full scale in use so the gain selection is automatic and not shown here. The first filter eliminates the DC component and the double mains frequency components of the demodulated output.

The configuration consists of a .05 Hz Low High Pass filter and a 6 Pole

Butterworth Low Pass filter located at 35 Hz. The second filter is a weighting filter that simulates the response of the human visual system to sinusoidal voltage fluctuations of a coiled filament, gas-filled lamp (60 W - 230 V). The filter implementation of this function is as specified in IEC 61000-4-15.

Block 4 is composed of a squaring multiplier and a Low Pass filter. The Human

Flicker Sensation via lamp, eye and brain is simulated by the combined non-linear response of Blocks 2, 3 and 4.

Block 5 performs an online statistical cumulative probability analysis of the flicker level. Block 5 allows direct calculation of the evaluation parameters Pst and Plt.

Flicker Evaluation occurs in the following forms: Instantaneous, Short Term or Long Term.

Each form is detailed below:

15.2.1 Instantaneous Flicker Evaluation

An output of 1.00 from Block 4 corresponds to the Reference Human Flicker Perceptibility

Threshold for 50% of the population. This value is measured in Perceptibility Units (PU) and is labeled Pinst. This is a real time value and it is continuously updated.

15.2.2 Short-Term Flicker Evaluation

An output of 1.00 from Block 5 (corresponding to the Pst value) corresponds to the conventional threshold of irritability per IEC 1000-3-3. In order to evaluate flicker severity, two parameters have been defined: one for the short term called Pst (defined in this section) and one for the long term called Plt (defined in the next section).

The standard measurement time for Pst is 10 minutes. Pst is derived from the time at level statistics obtained from the level classifier in Block 5 of the flicker meter. The following formula is used:

Where the percentiles P(0.1), P(1), P(3), P(10), P(50) are the flicker levels exceeded for 0.1, 1, 2,

20 and 50% of the time during the observation period. The suffix S in the formula indicates that the smoothed value should be used. The smoothed values are obtained using the following formulas:

P(1s) = (P(.7) + P(1) + P(1.5))/3

P(3s) = (P(2.2) + P(3) + P(4))/3

P(10s) = (P(6) + P(8) + P(10) + P(13) + P(17))/5

P(50s) = (P(30) + P(50) + P(80))/3

The .3-second memory time constant in the flicker meter ensures that P(0.1) cannot change abruptly and no smoothing is needed for this percentile.

(EQ 15.2)

(EQ 15.3)

(EQ 15.4)

(EQ 15.5)

15.2.3 Long-Term Flicker Evaluation

The 10-minute period on which the short-term flicker severity is based is suitable for short duty cycle disturbances. For flicker sources with long and variable duty cycles (e.g. arc furnaces) it is necessary to provide criteria for long-term assessment. For this purpose, the long-term Plt is derived from the short-term values over an appropriate period. By definition, this is 12 short-term values of 10 minutes each over a period of 2 hours. The following formula is used:

P lt

Deadband (%) (Object 32)

Any DNP Static Point can be configured to create DNP Event Points. Deadband and Class

Assignments on the Object 32 screen are used to configure Analog Change Event Points. In order to create Event Data, Object 32 Points must be assigned to Class 1, 2 or 3. Each point can have a different Class assignment.

Deadband (%) defines the boundary value for that point. For example, suppose One

Second Phase to Neutral Volts AN is programmed and the Voltage Full Scale is 120.00V for the meter. Entering 10% for Deadband will define the boundary value of 12V (10% of 120V).

Every second, new Static Data is scanned for One Second Phase to Neutral Volts AN. If the new data is different from the previous standard value by the boundary value, an Analog

Change Event will be created.

Example

If the previous standard value is 110 and new data is lower than 98V or higher than

122V, a new Analog Change Event Point will be created. The new value then becomes the previous standard value for future scans.

Analog Input Points have various Full Scales values due to different data types (Volts,

Amps, Watts, etc.). These Full Scale values are used for Exception Polling in DNP. Some

Full Scale values are programmable by users and others have fixed numbers. See the chart of Full Scale Values below.

GE COMMUNICATOR EXT – INSTRUCTION MANUAL 16–7

BINARY COUNTER (OBJECT 20) CHAPTER 16: CUSTOMIZING DNP V3.0 CONFIGURATION USING GE COMMUNICATOR EXT

Scaling

A meter can measure its Binary Counter value using up to a 16-digit number (0 to

9,999,999,999,999,999). DNP Binary Counter Points use up to 32 bits. That means that the range is 0 to 4,294,967,295 (0x0FFFFFFFF). This maximum number is only a 10-digit number. In order to deal with a 16-digit number, Scaling is necessary.

Scaling is used to select a unit in powers of 10: 1 = x10, 2 = x100 and so on. The Scaling value can be 0 to 15.

Example

If the value inside the meter is 3,000,000 and a Scaling value of 2 (x100) is used, the

Binary Counter value will be reported as 30000. The actual value is 30000x100 =

3,000,000.

Delta (Object 22)

Any DNP Static Point can be configured to create DNP Event Points. Delta and Class

Assignments on the Object 22 screen are used to configure Counter Change Event Points.

In order to create Event Data, Object 22 must be assigned to Class 1, 2 or 3. Each point can have a different Class Assignment.

The Delta value defines the boundary value for that point.

Example

Suppose VA hour is programmed and the Delta is 5. That represents 5 increments from the returned 32-bit Binary Counter value. Every second, new Static Data is scanned for

VA hour. If new data is different from the previous standard value by the Delta value, the Counter Change Event Data will be created. That means, if the previous standard polled value is 50000 VA hour and if the VA hour reading increases to 50005, it will create a Counter Change Event Point for VA hour and 50005 VA hour will become the previous standard value for the next Static Data.

The Scaling setting for a point also applies to the Delta value. If Delta is 5 and Scaling is 2, this indicates a 500-count change in the internal representation.

Object 23

Frozen Analog Event (Object 23) will be created if Object 23 is assigned to Class 1, 2 or 3.

B.1

Introduction

The Edison Electric Institute’s Handbook for Electricity Metering, Ninth Edition, defines Loss

Compensation as:

A means for correcting the reading of a meter when the metering point and point of service are physically separated, resulting in measurable losses including I2R losses in conductors and transformers and iron-core losses. These losses may be added to, or subtracted from, the meter registration.

Loss compensation may be used in any instance where the physical location of the meter does not match the electrical location where change of ownership occurs. Most often this appears when meters are connected on the low voltage side of power transformers when the actual ownership change occurs on the high side of the transformer. This condition is shown pictorially in Figure B.1.

FIGURE B–1: Low Voltage Metering Installation Requiring Loss Compensation Ownership Change

GE COMMUNICATOR EXT - INSTRUCTION MANUAL B–1

INTRODUCTION CHAPTER B: TRANSFORMER/LINE LOSS COMPENSATION CALCN. WORKSHEETS

It is generally less expensive to install metering equipment on the low voltage side of a transformer and in some conditions other limitations may also impose the requirement of low-side metering even though the actual ownership change occurs on the high-voltage side.

The need for loss compensated metering may also exist when the ownership changes several miles along a transmission line where it is simply impractical to install metering equipment. Ownership may change at the midway point of a transmission line where there are no substation facilities. In this case, power metering must again be compensated. This condition is shown in Figure B.2.

B–2

FIGURE B–2: Joint Ownership Line Metering Requiring Loss Compensation M Point of Ownership

Change

A single meter cannot measure the losses in a transformer or transmission line directly. It can however, include computational corrections to calculate the losses and add or subtract those losses to the power flow measured at the meter location. This is the method used for loss compensation in the EPM meter.

The computational corrections used for transformer and transmission line loss compensation are similar. Generically, no-load losses and full-load losses are evaluated and a correction factor for each loss level is calculated. However, the calculation of the correction factors that must be programmed into the meter differ for the two different applications. For this reason, the two methodologies will be treated separately in this chapter.

In the EPM 9450, 9650 and 9800 meters, Loss Compensation is a technique that computationally accounts for active and reactive power losses. The meter calculations are based on the formulas below. These equations describe the amount of active (Watts) and reactive (VARs) power lost due to both iron and copper effects (reflected to the secondary of the instrument transformers).

Total Secondary Watt Loss = (((Measured Voltage/Cal point Voltage)

x %LWFE) +

((Measured Current/Cal Point Current)

Total Secondary VAR Loss = (((Measured Voltage/Cal point Voltage)

4

x %LVFE) + ((Measured

Current/Cal Point Current)

2

x %LVCU)) x Full-scale Secondary VA

• The Values for %LWFE, %LWCU, %LVFE, %LVCU are derived from the transformer and meter information, as demonstrated in following sections.

• The calculated loss compensation values are added to or subtracted from the measured Watts and VARs.

• The selection of adding or subtracting losses is made through the meter profile when programming the meter.

GE COMMUNICATOR EXT - INSTRUCTION MANUAL

CHAPTER B: TRANSFORMER/LINE LOSS COMPENSATION CALCN. WORKSHEETS INTRODUCTION

• The meter uses the combination of the add/subtract setting and the directional definition of power flow (also in the profile) to determine how to handle the losses.

• Losses will be "added to" or "subtracted from" (depending on whether add or subtract is selected) the Received Power flow.

Example

If losses are set to "Add to" and received power equals 2000 kW and losses are equal to 20kW then the total metered value with loss compensation would be 2020 kW; for these same settings if the meter measured 2000 kW of delivered power the total metered value with loss compensation would be 1980 kW.

Since transformer loss compensation is the more common loss compensation method, the meter has been designed for this application. Line loss compensation is calculated in the meter using the same terms but the percent values are calculated by a different methodology as described in a subsequent section below.

Note

B.1.1 Transformer/Line Loss Compensation

• Performs calculations on each phase of the meter for every measurement taken.

Unbalanced loads are accurately handled.

• Calculates numerically, eliminating the environmental affects that cause inaccuracies in electromechanical compensators.

• Performs Bidirectional Loss Compensation.

• Requires no additional wiring; the compensation occurs internally.

• Imposes no additional electrical burden when performing Loss Compensation.

Loss Compensation is applied to 1 second per phase Watt/VAR readings and, because of that, affects all subsequent readings based on 1 second per phase Watt/VAR readings.

This method results in loss compensation be applied to the following quantities:

• Total Power.

• Demands, per phase and Total (Thermal, Block (Fixed) Window, Rolling (Sliding)

Window and Predictive Window).

• Maximum and Minimum Demands.

• Energy Accumulations.

• KYZ Output of Energy Accumulations.

Loss Compensation is disabled when the meter is placed in Test Mode.

TRANSFORMER / LINE LOSS COMPENSATION CHAPTER B: TRANSFORMER/LINE LOSS COMPENSATION CALCN. WORKSHEETS

B.2

Transformer / Line Loss Compensation

The meter provides compensation for active and reactive power quantities by performing the numerical calculations using factors derived in two ways; using the TLC Calculator button on the Transformer Loss screen of the Meter’s Device Profile or using the worksheet found in section B.2.1, (Calculating Transformer Loss Compensation Percentages Work

Sheet). Enter the derived values in the Device Profile screen of the GE Communicator EXT software.

The GE Communicator EXT software allows you to enable Transformer Loss Compensation for Losses due to Copper and Iron, individually or simultaneously. Losses can either be added to, or subtracted from, measured readings.

Loss compensation values must be calculated based on the meter installation. As a result transformer loss values must be normalized to the meter by converting the base voltage and current and taking into account the number of elements used in the metering installation.

For three element meters, the installation must be normalized to the phase-to-neutral voltage and the phase current; in two element meters the installation must be normalized to the phase-to-phase voltage and the phase current. This process is described in the following sections.

B.2.1 Loss Compensation in Three Element Installations

Loss Compensation is based on the loss and impedance values provided on the

Transformer Manufacturer’s Test Report. A typical test report will include at least the following information:

• Manufacturer

• Unit Serial Number

• Transformer MVA Rating (Self-Cooled)

• Test Voltage

• No Load Loss Watts

• Load Loss Watts (or Full Load Loss Watts)

• % Exciting Current @ 100% voltage

• % Impedance

The transformer MVA rating is generally the lowest MVA rating (the self-cooled or OA rating) of the transformer winding. The test voltage is generally the nominal voltage of the secondary or low voltage winding. For three phase transformers these values will typically be the three-phase rating and the phase-to-phase voltage. All of the test measurements are based on these two numbers. Part of the process of calculating the loss compensation percentages is converting the transformer loss values based on the transformer ratings to the base used by the meter.

Correct calculation of loss compensation also requires knowledge of the meter installation.

In order to calculate the loss compensation settings you will need the following information regarding the meter and the installation:

• Number of meter elements

A short label that identifies particular quantities or values displayed, for example kWh.

When applied to current values (amps) the average is a calculated value that corresponds to the thermal average over a specified time interval. The interval is specified by the user in the meter profile. The interval is typically 15 minutes. So, Average Amps is the thermal average of amps over the previous 15-minute interval.

The thermal average rises to 90% of the actual value in each time interval. For example, if a constant 100amp load is applied, the thermal average will indicate 90 amps after one time interval, 99 amps after two time intervals and 99.9 amps after three time intervals.

When applied to Input Pulse Accumulations, the

When applied to power values (watts, VARs, VA), the average is a calculated value that corresponds to the thermal average over a specified time interval. The interval is specified by the user in the meter profile. The interval is typically 15 minutes. So, the Average Watts is the thermal average of watts over the previous 15minute interval. The thermal average rises to 90% of the actual value in each time interval. For example, if a constant 100kW load is applied, the thermal average will indicate 90kW after one time interval, 99kW after two time intervals and 99.9kW after three time intervals.

EPM 9800 meter. Using an ANSI C12.13 Type II magnetic optical communications coupler and an RS-232 cable from the coupler to a PC, the meter can be programmed with GE Communicator EXT software.

A short fixed-length section of data that is transmitted as a unit. Example: a serial string of 8-bit bytes.

Percent Total Harmonic Distortion. (See THD.)

A language that will be spoken between two or more devices connected on a network.

Potential Transformer Ratio used to scale the value of the voltage to the primary side of an instrument transformer. Also referred to as VT Ratio.

The closing and opening of the circuit of a two-wire pulse system or the alternate closing and opening of one side and then the other of a three-wire system

(which is equal to two pulses).

Q is the quantity obtained by lagging the applied voltage to a wattmeter by 60 degrees. Values are displayed on the Uncompensated Power and Q Readings screen.

Watt and VAR flow is typically represented using an X-Y coordinate system. The four corners of the X-Y plane are referred to as quadrants. Most power applications label the right hand corner as the first quadrant and number the, remaining quadrants in a counter-clockwise rotation. Following are the positions of the quadrants:

1st - upper right, 2nd - upper left, 3rd - lower left and 4th

- lower right. Power flow is generally positive in quadrants 1 and 4. VAR flow is positive in quadrants 1 and 2. The most common load conditions are: Quadrant

1 - power flow positive, VAR flow positive, inductive load, lagging or positive power factor; Quadrant 2 - power flow negative, VAR flow positive, capacitive load, leading or negative power factor.

An entry or record that stores a small amount of data.

A point at which a Register reaches its maximum value and rolls over to zero.

Logs are cleared or new (or default) values are sent to counters or timers.

The Rolling (Sliding) Window Average is the average power calculated over a user-set time interval that is derived from a specified number of sub-intervals, each of a specified time. For example, the average is calculated over a 15-minute interval by calculating the sum of the average of three consecutive 5-minute intervals. This demand calculation methodology has been adopted by several utilities to prevent customer manipulation of kW demand by simply spreading peak demand across two intervals.

A type of serial network connection that connects two devices to enable communication between devices. An

RS-232 connection connects only two points. Distance between devices is typically limited to fairly short runs.

Current standards recommend a maximum of 50 feet but some users have had success with runs up to 100 feet. Communications speed is typically in the range of

1200 bits per second to 57,600 bits per second. RS-232 connection can be accomplished using Port 1 of the EPM

9450/9650 or the Optical Port on the face of the EPM

9800.

A type of serial network connection that connects two or more devices to enable communication between the devices. An RS-485 connection will allow multi-drop communication from one to many points. Distance between devices is typically limited to around 2,000 to

3,000 wire feet. Communications speed is typically in the range of 120 bits per second to 115,000 bits per second.

A voltage quality event during which the RMS voltage is lower than normal for a period of time, typically from 1/2 cycle to 1 minute.

Any Register or pulse output that does not use any CT or

VT Ratio.

The type of port used to directly interface with a PC.

In Modbus communication, a Slave Device only receives a Request Packet from a Master Device and responds to the request. A Slave Device cannot initiate communication.

A voltage quality event during which the RMS voltage is higher than normal for a period of time, typically from 1/

2 cycle to 1 minute.

THD:

Time Stamp:

Total Harmonic Distortion is the combined effect of all harmonics measured in a voltage or current. The THD number is expressed as a percent of the fundamental.

For example, a 3% THD indicates that the magnitude of all harmonic distortion measured equals 3% of the magnitude of the fundamental 60Hz quantity.

A stored representation of the time of an event. Time

Voltage Imbalance:

Data will stop accumulating when voltage falls below programmed level.

The ratio of the voltage on a phase to the average voltage on all phases.

Voltage Quality Event:

An instance of abnormal voltage on a phase. The events the meter will track include sags, swells, interruptions and imbalances.

VT Ratio:

The Voltage Transformer Ratio is used to scale the value of the voltage to the primary side of an instrument transformer. Also referred to as PT Ratio.

GLOSSARY

Vab, Vbc, Vca are all Phase-to-Phase voltage measurements. These voltages are measured between the three phase voltage inputs to the meter.

Van, Vbn, Vcn are all Phase-to-Neutral voltages applied to the monitor. These voltages are measured between the phase voltage inputs and Vn input to the meter.

Technologically, these voltages can be “measured” even when the meter is in a Delta configuration and there is no connection to the Vn input. However, in this configuration, these voltages have limited meaning and are typically not reported.

This is the fourth voltage input measured from between the Vaux and Vref inputs. This input can be scaled to any value. However, the actual input voltage to the meter should be of the same magnitude as the voltages applied to the Va, Vb and Vc terminals.
