REM611 overview

Overview

REM611 is a dedicated motor protection relay for the protection, control, measurement and supervision of asynchronous motors in manufacturing and process industry. Typically, the relay is used with circuit breaker or contactor-controlled medium-sized or small motors in a variety of drives, such as pumps and conveyors, crushers and choppers, mixers and agitators, and fans and aerators.

REM611 is a member of ABB’s Relion ® product family and part of the 611 protection and control product series. The 611 series relays are characterized by their compactness and withdrawable-unit design.

The 611 series offers simplified yet powerful functionality for most applications.

Once the application-specific parameter set has been entered, the installed protection relay is ready to be put into service. The further addition of communication functionality and interoperability between substation automation devices offered by the IEC 61850 standard adds flexibility and value to end users as well as electrical system manufacturers.

The 611 series relays fully support the IEC 61850 standard for communication and interoperability of substation automation devices, including fast GOOSE (Generic

Object Oriented Substation Event) messaging, and can now also benefit from the extended interoperability provided by Edition 2 of the standard. The relays further support the parallel redundancy protocol (PRP) and the high-availability seamless redundancy (HSR) protocol. The 611 series relays are able to use IEC 61850 and

Modbus® communication protocols simultaneously.

Audit trail

The protection relay offers a large set of event-logging functions. Critical system and protection relay security-related events are logged to a separate nonvolatile audit trail for the administrator.

Audit trail is a chronological record of system activities that allows the reconstruction and examination of the sequence of system and security-related events and changes in the protection relay. Both audit trail events and process related events can be examined and analyzed in a consistent method with the help of Event List in LHMI and WHMI and Event Viewer in PCM600.

The protection relay stores 2048 audit trail events to the nonvolatile audit trail.

Additionally, 1024 process events are stored in a nonvolatile event list. Both the audit trail and event list work according to the FIFO principle. Nonvolatile memory is based on a memory type which does not need battery backup nor regular component change to maintain the memory storage.

Audit trail events related to user authorization (login, logout, violation remote and violation local) are defined according to the selected set of requirements from IEEE

1686. The logging is based on predefined user names or user categories. The user audit trail events are accessible with IEC 61850-8-1, PCM600, LHMI and WHMI.

PCM600 Event Viewer can be used to view the audit trail events and process related events. Audit trail events are visible through dedicated Security events view. Since only the administrator has the right to read audit trail, authorization must be used in

PCM600. The audit trail cannot be reset, but PCM600 Event Viewer can filter data.

Audit trail events can be configured to be visible also in LHMI/WHMI Event list together with process related events.

To expose the audit trail events through Event list, define the

Authority logging level parameter via Configuration/

Authorization/Security . This exposes audit trail events to all users.

Communication

The protection relay supports a range of communication protocols including IEC

61850 and Modbus ® . Operational information and controls are available through these protocols. However, some communication functionality, for example, horizontal communication between the protection relays, is only enabled by the IEC

61850 communication protocol.

The IEC 61850 communication implementation supports all monitoring and control functions. Additionally, parameter settings, disturbance recordings and fault records can be accessed using the IEC 61850 protocol. Disturbance recordings are available to any Ethernet-based application in the IEC 60255-24 standard COMTRADE file format. The protection relay can send and receive binary signals from other devices

(so-called horizontal communication) using the IEC 61850-8-1 GOOSE profile,

1MRS757457 E where the highest performance class with a total transmission time of 3 ms is supported. The protection relay meets the GOOSE performance requirements for tripping applications in distribution substations, as defined by the IEC 61850 standard.

The protection relay can support five simultaneous clients. If PCM600 reserves one client connection, only four client connections are left, for example, for IEC 61850 and Modbus.

All communication connectors, except for the front port connector, are placed on integrated optional communication modules. The protection relay can be connected to

Ethernet-based communication systems via the RJ-45 connector (100Base-TX) or the fiber-optic LC connector (100Base-FX). An optional serial interface is available for

RS-485 communication.

Self-healing Ethernet ring

For the correct operation of self-healing loop topology, it is essential that the external switches in the network support the RSTP protocol and that it is enabled in the switches. Otherwise, connecting the loop topology can cause problems to the network. The protection relay itself does not support link-down detection or RSTP.

The ring recovery process is based on the aging of the MAC addresses, and the linkup/link-down events can cause temporary breaks in communication. For a better performance of the self-healing loop, it is recommended that the external switch furthest from the protection relay loop is assigned as the root switch (bridge priority

= 0) and the bridge priority increases towards the protection relay loop. The end links of the protection relay loop can be attached to the same external switch or to two adjacent external switches. A self-healing Ethernet ring requires a communication module with at least two Ethernet interfaces for all protection relays.

Figure 6: Self-healing Ethernet ring solution

The Ethernet ring solution supports the connection of up to 30 protection relays. If more than 30 protection relays are to be connected, it is recommended that the network is split into several rings with no more than 30 protection relays per ring. Each protection relay has a 50-μs store-and-forward delay, and to fulfil the performance requirements for fast horizontal communication, the ring size is limited to 30 protection relays.

Ethernet redundancy

IEC 61850 specifies a network redundancy scheme that improves the system availability for substation communication. It is based on two complementary protocols defined in the IEC 62439-3:2012 standard: parallel redundancy protocol

PRP and high-availability seamless redundancy HSR protocol. Both protocols rely on the duplication of all transmitted information via two Ethernet ports for one logical network connection. Therefore, both are able to overcome the failure of a link or switch with a zero-switchover time, thus fulfilling the stringent real-time requirements for the substation automation horizontal communication and time synchronization.

PRP specifies that each device is connected in parallel to two local area networks.

HSR applies the PRP principle to rings and to the rings of rings to achieve costeffective redundancy. Thus, each device incorporates a switch element that forwards frames from port to port. The HSR/PRP option is available for all 611 series protection relays.

Section 2

REM611 overview

1MRS757457 E

IEC 62439-3:2012 cancels and replaces the first edition published in

2010. These standard versions are also referred to as IEC 62439-3

Edition 1 and IEC 62439-3 Edition 2. The protection relay supports

IEC 62439-3:2012 and it is not compatible with IEC 62439-3:2010.

PRP

Each PRP node, called a double attached node with PRP (DAN), is attached to two independent LANs operated in parallel. These parallel networks in PRP are called

LAN A and LAN B. The networks are completely separated to ensure failure independence, and they can have different topologies. Both networks operate in parallel, thus providing zero-time recovery and continuous checking of redundancy to avoid communication failures. Non-PRP nodes, called single attached nodes (SANs), are either attached to one network only (and can therefore communicate only with

DANs and SANs attached to the same network), or are attached through a redundancy box, a device that behaves like a DAN.

Figure 7: PRP solution

In case a laptop or a PC workstation is connected as a non-PRP node to one of the PRP networks, LAN A or LAN B, it is recommended to use a redundancy box device or an

Ethernet switch with similar functionality between the PRP network and SAN to remove additional PRP information from the Ethernet frames. In some cases, default

PC workstation adapters are not able to handle the maximum-length Ethernet frames with the PRP trailer.

There are different alternative ways to connect a laptop or a workstation as SAN to a

PRP network.

Section 2

REM611 overview

• Via an external redundancy box (RedBox) or a switch capable of connecting to

PRP and normal networks

• By connecting the node directly to LAN A or LAN B as SAN

• By connecting the node to the protection relay's interlink port

HSR

HSR applies the PRP principle of parallel operation to a single ring, treating the two directions as two virtual LANs. For each frame sent, a node, DAN, sends two frames, one over each port. Both frames circulate in opposite directions over the ring and each node forwards the frames it receives, from one port to the other. When the originating node receives a frame sent to itself, it discards that to avoid loops; therefore, no ring protocol is needed. Individually attached nodes, SANs, such as laptops and printers, must be attached through a “redundancy box” that acts as a ring element. For example, a 615 or 620 series protection relay with HSR support can be used as a redundancy box.

Secure communication

The protection relay supports secure communication for WHMI and file transfer protocol. If the Secure Communication parameter is activated, protocols require TLS based encryption method support from the clients. In this case WHMI must be connected from a Web browser using the HTTPS protocol and in case of file transfer the client must use FTPS.

As a factory default, Secure Communication is “ON”.

Switch groups

The default application configurations cover the most common application cases, however, changes can be made according to specific needs through LHMI, WHMI and PCM600.

Programming is easily implemented with three switch group functions including input switch group ISWGAPC, output switch group OSWGAPC and selector switch group

SELGAPC. Each switch group has several instances.

Connections of binary inputs to functions, GOOSE signals to functions, functions to functions, functions to binary outputs and functions to LEDs have been preconnected through corresponding switch groups.

The real connection logic and the application configuration can be modified by changing the parameter values of the switch groups. It is also possible to modify the real connection logic and the application configuration through the matrix view in the signal configuration menu in the WHMI.

Input switch group ISWGAPC

The input switch group ISWGAPC has one input and a number of outputs. Every input and output has a read-only description. ISWGAPC is used for connecting the input

The protection principles are mostly the same for circuit-breaker controlled and contactor controlled motor drives. Because the contactor is not able to break high currents, the relay must be set in such a way that the relay does not open the contactor at faults of high current magnitudes. Faults are cleared with fuses.

Additionally, all the digital inputs that are connected by default are also enabled with the setting. Default triggering settings are selected depending on the connected input signal type. Typically all protection START signals are selected to trigger the disturbance recorded by default.

Functional diagrams

The functional diagrams describe the default input, output, programmable LED, switch group and function-to-function connections. The default connections can be viewed and changed with switch groups in PCM600, LHMI and WHMI according to the application requirements.

The analog channels have fixed connections towards the different function blocks inside the protection relay’s configuration. Exceptions from this rule are the seven analog channels available for the disturbance recorder function. These channels are freely selectable and a part of the disturbance recorder’s parameter settings.

The analog channels are assigned to different functions. The common signal marked with 3I represents the three phase currents. The signal marked with Io represents the measured residual current via a core balance current transformer.

Figure 17: Emergency start and restart inhibit

The emergency start function ESMGAPC1 allows motor start-ups although the restart inhibit is activated. The emergency start is enabled for ten minutes after the selected binary input (X120:BI1) is energized. On the rising edge of the emergency start signal the following takes place.

• Calculated thermal level is set slightly below the restart inhibit level to allow at least one motor startup.

• Value of the cumulative start-up time counter STTPMSU1 is set slightly below the set restart inhibit value to allow at least one motor startup.

• Set operate values of the temperature stages in MPTTR1 function is increased by

10 percent.

• External restart inhibit signal (X100:PO1) is ignored.

• Alarm LED 5 is activated.

The external restart inhibit signal is ignored for as long as the emergency start is activated. A new emergency start cannot be made until the emergency start signal has been reset and the emergency start time of 10 minutes has expired.

The thermal overload protection function MPTTR1 detects short- and long term overloads under varying load conditions. When the emergency start request is issued for the emergency start function, it activates the corresponding input of the thermal overload function. When the thermal overload function has issued a restart blocking, which inhibits the closing of the circuit breaker when the machine is overloaded, the emergency start request removes this blocking and enables the restarting of the motor.

The operate signal of thermal overload protection function MPTTR1 is connected to

Master Trip and to alarm LED 3.

The restart inhibit is activated for a set period when a circuit breaker is opened. This is called remanence voltage protection where the motor has damping remanence voltage after circuit breaker opening. Reclosing after a too short period of time can lead to stress for the machine and other apparatuses. The remanence voltage protection waiting time can be set to a timer function TPSGAPC1.

The restart inhibit is also activated when one of the following conditions is met.

• An active trip command or

• Motor startup supervision has issued lockout or

• Motor unbalance function has issued restart blocking or

• An external restart inhibit is activated by a binary input (X120:BI4).

When the emergency start request is activated by ESMCAPC1 and STTPMSU1 is in lockout state, which inhibits motor starting, the lockout is deactivated and emergency starting is available.

The operate signals (OPR_IIT and OPR_STALL) of the motor start-up supervision function STTPMSU1 are connected to Master Trip and to alarm LED 2.

The motor running time counter MDSOPT1 provides history data since the latest commissioning. The counter counts the total number of motor running hours and is

Figure 19: Unbalance, loss of load and phase reversal protection

Two negative-sequence overcurrent stages MNSPTOC1 and MNSPTOC2 are offered for phase unbalance protection. These functions are used to protect the motor against phase unbalance caused by, for example, a broken conductor. Phase unbalance in network feeding of the motor causes overheating of the motor.

The loss of load situation is detected by LOFLPTUC. The loss of load situation can happen, for example, if there is damaged pump or a broken conveyor.

Section 3

REM611 standardized configuration

The phase reversal protection PREVPTOC1 is based on the calculated negative phase-sequence current. It detects too high NPS current values during motor start-up, caused by incorrectly connected phases, which in turn causes the motor to rotate in the opposite direction.

All operate signals above are connected to Master Trip and to the alarm LED 2.

Figure 20: Circuit breaker failure protection

The circuit-breaker failure protection CCBRBRF1 is initiated via the start input by a number of different protection stages in the protection relay. CCBRBRF1 offers different operating modes associated with the circuit-breaker position and the measured phase and residual currents.

CCBRBRF1 has two operating outputs: TRRET and TRBU . The TRRET operate output is used for retripping its own circuit breaker through the Master Trip 1. The

TRBU output is used to give a backup trip to the circuit breaker feeding upstream. For this purpose, the TRBU operate output signal is connected to the output PO2 (X100:

8-9). LED 8 is used for backup ( TRBU ) operate indication.

In the configuration, there are 20 GOOSERCV_BIN functions and 1

GOOSERCV_MV function. Each GOOSERVC_BIN function can be connected to one received binary GOOSE signal and the GOOSERVC_MV function can be connected to one received analog GOOSE signal. The signal connection can be configured in PCM600.

• GOOSERCV_BIN instances 0 and 1 are used for blocking protection functions.

Signals from these two GOOSERCV_BINs are connected to ISWGAPC9.

ISWGAPC9 is used to configure which protection function block is blocked.

• GOOSERCV_BIN instances 2 and 3 are used for tripping from GOOSE. Signals from these two GOOSERCV_BINs are connected to TRPPTRC1 trip.

• GOOSERCV_BIN instances 4 to 19 are used for blocking the circuit breaker operation. Signals from these 16 GOOSERCV_BINs are connected to

ISWGAPC10. ISWGAPC10 is used to configure the GOOSE input signal to block the circuit breaker open or close operation.

• GOOSERCV_MV instance 1 is used for ambient temperature measurement from

GOOSE. Signal from this GOOSERCV_MV is connected to the input

AMB_TEMP of MPTTR1.

Current transformers

Current transformer requirements for overcurrent protection

For reliable and correct operation of the overcurrent protection, the CT has to be chosen carefully. The distortion of the secondary current of a saturated CT may endanger the operation, selectivity, and co-ordination of protection. However, when the CT is correctly selected, a fast and reliable short circuit protection can be enabled.

The selection of a CT depends not only on the CT specifications but also on the network fault current magnitude, desired protection objectives, and the actual CT burden.

Current transformer accuracy class and accuracy limit factor

The rated accuracy limit factor (F n

) is the ratio of the rated accuracy limit primary current to the rated primary current. For example, a protective current transformer of type 5P10 has the accuracy class 5P and the accuracy limit factor 10. For protective current transformers, the accuracy class is designed by the highest permissible percentage composite error at the rated accuracy limit primary current prescribed for the accuracy class concerned, followed by the letter "P" (meaning protection).

The accuracy classes 5P and 10P are both suitable for non-directional overcurrent protection. The 5P class provides a better accuracy.

The CT accuracy primary limit current describes the highest fault current magnitude at which the CT fulfils the specified accuracy.

In practise, the actual accuracy limit factor (F a

) differs from the rated accuracy limit factor (F n

) and is proportional to the ratio of the rated CT burden and the actual CT burden.

Non-directional overcurrent protection

The current transformer selection

Non-directional overcurrent protection does not set high requirements on the accuracy class or on the actual accuracy limit factor (F a

) of the CTs. It is, however, recommended to select a CT with F a

of at least 20.

The nominal primary current I

1n

should be chosen in such a way that the thermal and dynamic strength of the current measuring input of the protection relay is not exceeded. This is always fulfilled when

I

1n

> I kmax

/ 100,

I kmax

is the highest fault current.

The saturation of the CT protects the measuring circuit and the current input of the protection relay. For that reason, in practice, even a few times smaller nominal primary current can be used than given by the formula.

Recommended start current settings

If I kmin

is the lowest primary current at which the highest set overcurrent stage is to operate, the start current should be set using the formula:

Current start value < 0.7 × (I kmin

/ I

1n

)

I

1n

is the nominal primary current of the CT.

The factor 0.7 takes into account the protection relay inaccuracy, current transformer errors, and imperfections of the short circuit calculations.

The adequate performance of the CT should be checked when the setting of the high set stage overcurrent protection is defined. The operate time delay caused by the CT saturation is typically small enough when the overcurrent setting is noticeably lower than F a

.

4.1.1.3

Section 4

Requirements for measurement transformers

When defining the setting values for the low set stages, the saturation of the CT does not need to be taken into account and the start current setting is simply according to the formula.

Delay in operation caused by saturation of current transformers

The saturation of CT may cause a delayed protection relay operation. To ensure the time selectivity, the delay must be taken into account when setting the operate times of successive protection relays.

With definite time mode of operation, the saturation of CT may cause a delay that is as long as the time constant of the DC component of the fault current, when the current is only slightly higher than the starting current. This depends on the accuracy limit factor of the CT, on the remanence flux of the core of the CT, and on the operate time setting.

With inverse time mode of operation, the delay should always be considered as being as long as the time constant of the DC component.

With inverse time mode of operation and when the high-set stages are not used, the AC component of the fault current should not saturate the CT less than 20 times the starting current. Otherwise, the inverse operation time can be further prolonged.

Therefore, the accuracy limit factor F a

should be chosen using the formula:

F a

> 20 × Current start value / I

1n

The Current start value is the primary start current setting of the protection relay.

Example for non-directional overcurrent protection

The following figure describes a typical medium voltage feeder. The protection is implemented as three-stage definite time non-directional overcurrent protection.

Figure 55: Example of three-stage overcurrent protection

The maximum three-phase fault current is 41.7 kA and the minimum three-phase short circuit current is 22.8 kA. The actual accuracy limit factor of the CT is calculated to be 59.

The start current setting for low-set stage (3I>) is selected to be about twice the nominal current of the cable. The operate time is selected so that it is selective with the

next protection relay (not visible in Figure 55

). The settings for the high-set stage and instantaneous stage are defined also so that grading is ensured with the downstream protection. In addition, the start current settings have to be defined so that the protection relay operates with the minimum fault current and it does not operate with the maximum load current. The settings for all three stages are as in

Figure 55 .

For the application point of view, the suitable setting for instantaneous stage (I>>>) in this example is 3 500 A (5.83 × I

2n

). I

2n

is the 1.2 multiple with nominal primary current of the CT. For the CT characteristics point of view, the criteria given by the current transformer selection formula is fulfilled and also the protection relay setting is considerably below the F a

. In this application, the CT rated burden could have been selected much lower than 10 VA for economical reasons.
