Web HMI
The WHMI allows secure access to the protection relay via a Web browser. When the
Secure Communication parameter in the protection relay is activated, the Web server is forced to take a secured (HTTPS) connection to WHMI using TLS encryption. The WHMI is verified with Internet Explorer 8.0, 9.0, 10.0 and 11.0.
WHMI is disabled by default.
Control operations are not allowed by WHMI.
WHMI offers several functions.
• Programmable LEDs and event lists
• System supervision
• Parameter settings
• Measurement display
• Disturbance records
• Fault records
• Load profile record
• Phasor diagram
• Single-line diagram
• Importing/Exporting parameters

Authorization
Four user categories have been predefined for the LHMI and the WHMI, each with different rights and default passwords.
The default passwords in the protection relay delivered from the factory can be changed with Administrator user rights.
If the relay-specific Administrator password is forgotten, ABB can provide a onetime reliable key to access the protection relay. For support, contact ABB. The recovery of the Administrator password takes a few days.
User authorization is disabled by default for LHMI but WHMI always uses authorization.

2.6.1
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.

Application Manual
Communication
The protection relay supports a range of communication protocols including IEC
61850, IEC 61850-9-2 LE, IEC 60870-5-103, Modbus ® and DNP3. Profibus DPV1 communication protocol is supported by using the protocol converter SPA-ZC 302.
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, where the highest performance class with a total transmission time of 3 ms is supported. Furthermore, the protection relay supports sending and receiving of analog values using GOOSE messaging. 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

1MRS757655 E connected to Ethernet-based communication systems via the RJ-45 connector
(100Base-TX) or the fiber-optic LC connector (100Base-FX).
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.

2.7.2

Figure 7: 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
REM620
Application Manual
1MRS757655 E REM620 overview 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 620 series protection relays.
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.

Application Manual
Figure 8: 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,
31
REM620 overview 1MRS757655 E 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.
• 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.

Process bus
Process bus IEC 61850-9-2 defines the transmission of Sampled Measured Values within the substation automation system. International Users Group created a guideline IEC 61850-9-2 LE that defines an application profile of IEC 61850-9-2 to facilitate implementation and enable interoperability. Process bus is used for distributing process data from the primary circuit to all process bus compatible devices in the local network in a real-time manner. The data can then be processed
REM620
Application Manual
1MRS757655 E REM620 overview by any protection relay to perform different protection, automation and control functions.
UniGear Digital switchgear concept relies on the process bus together with current and voltage sensors. The process bus enables several advantages for the UniGear
Digital like simplicity with reduced wiring, flexibility with data availability to all devices, improved diagnostics and longer maintenance cycles.
With process bus the galvanic interpanel wiring for sharing busbar voltage value can be replaced with Ethernet communication. Transmitting measurement samples over process bus brings also higher error detection because the signal transmission is automatically supervised. Additional contribution to the higher availability is the possibility to use redundant Ethernet network for transmitting SMV signals.

Station bus (IEC 61850-8-1), process bus (IEC 61850-9-2 LE) and IEEE 1588 v2 time synchronization
REM620
Application Manual
Figure 10: Process bus application of voltage sharing and synchrocheck
The 620 series supports IEC 61850 process bus with sampled values of analog currents and voltages. The measured values are transferred as sampled values using the IEC 61850-9-2 LE protocol which uses the same physical Ethernet network as the IEC 61850-8-1 station bus. The intended application for sampled values is sharing the measured voltages from one 620 series protection relay to other devices with phase voltage based functions and 9-2 support.
The 620 series protection relays with process bus based applications use IEEE 1588 v2 Precision Time Protocol (PTP) according to IEEE C37.238-2011 Power Profile for high accuracy time synchronization. With IEEE 1588 v2, the cabling infrastructure requirement is reduced by allowing time synchronization information to be transported over the same Ethernet network as the data communications.

1588 v2 support (COM0031...COM0034 or COM0037). See the IEC 61850 engineering guide for detailed system requirements and configuration details.
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.

Default configuration
The 620 series relays are configured with default configurations, which can be used as examples of the 620 series engineering with different function blocks. The default configurations are not aimed to be used as real end-user applications. The end-users always need to create their own application configuration with the configuration tool. However, the default configuration can be used as a starting point by modifying it according to the requirements.
REM620 is available in two alternative default configurations: configuration A with traditional current and voltage measurement transducers and configuration B with current and voltage sensors. The default configuration can be altered by means of the graphical signal matrix or the graphical application functionality of the
Protection and Control IED Manager PCM600. Furthermore, the application configuration functionality of the PCM600 supports the creation of multi-layer logic functions using various logical elements including timers and flip-flops. By combining protection functions with logic function blocks, the relay configuration can be adapted to user-specific application requirements.

Addition of control functions for primary devices and the use of binary inputs and outputs
If extra control functions intended for controllable primary devices are added to the configuration, additional binary inputs and/or outputs are needed to complement the default configuration.
If the number of inputs and/or outputs in a default configuration is not sufficient, it is possible either to modify the chosen default configuration in order to release some binary inputs or binary outputs which have originally been configured for other purposes, or to connect an external input/output module, for example
RIO600, to the protection relay.
The external I/O module’s binary inputs and outputs can be used for the less timecritical binary signals of the application. The integration enables releasing some initially reserved binary inputs and outputs of the protection relay’s default configuration.
The suitability of the protection relay’s binary outputs which have been selected for primary device control should be carefully verified, for example make and carry and breaking capacity. If the requirements for the primary device control circuit are not met, using external auxiliary relays should be considered.
LED functionality
The protection relay has dynamic programmable LEDs. The presentation of the
LEDs in this manual differs from the actual function blocks in the configurations.

Presentation of default configurations
Functional diagrams
The functional diagrams describe the IED's functionality from the protection, measuring, condition monitoring, disturbance recording, control and interlocking perspective. Diagrams show the default functionality with simple symbol logics forming principle diagrams. The external connections to primary devices are also shown, stating the default connections to measuring transformers.The positive measuring direction of directional protection functions is towards the outgoing feeder.
The functional diagrams are divided into sections with each section constituting one functional entity. The external connections are also divided into sections. Only the relevant connections for a particular functional entity are presented in each section.
Protection function blocks are part of the functional diagram. They are identified based on their IEC 61850 name but the IEC based symbol and the ANSI function number are also included. Some function blocks, such as PHHPTOC, are used several times in the configuration. To separate the blocks from each other, the IEC 61850 name, IEC symbol and ANSI function number are appended with a running number, that is an instance number, from one upwards.
Signal Matrix and Application Configuration
With Signal Matrix and Application Configuration in PCM600, it is possible to modify the default configuration according to the actual needs. The IED is delivered from the factory with default connections described in the functional diagrams for binary inputs, binary outputs, function-to-function connections and alarm LEDs.
The Signal Matrix tool is used for GOOSE signal input engineering and for making cross-references between the physical I/O signals and the function blocks. The
Signal Matrix tool cannot be used for adding or removing function blocks, for example, GOOSE receiving function blocks. The Application Configuration tool is used for these kind of operations. If a function block is removed with Application
Configuration, the function-related data disappears from the menus as well as from the 61850 data model, with the exception of some basic functions (61850 logical nodes), which are mandatory and thus cannot be removed from the IED configuration by removing them from Application Configuration.

3.5.1
Default configuration A
Applications
The default configuration is designed for differential protection and mainly intended for comprehensive protection and control functionality of circuit breaker controlled asynchronous motors. With minor modifications this default configuration can be applied also for contactor controlled motors.
The IED with a default configuration is delivered from the factory with default settings and parameters. The end-user flexibility for incoming, outgoing and internal signal designation within the IED enables this configuration to be further adapted to different primary circuit layouts and the related functionality needs by modifying the internal functionality using PCM600.
The default configuration can also be used with double bus arrangements. If the voltages are measured from the bus side in a double busbar configuration, an external voltage switch is needed to bring the right voltage set to the IED.
The configuration can also be modified to be used with several different start connection schemes by utilizing the available controllable blocks.

Description
The analog channel is assigned to the function by default.
The function can be set to use residual voltage or current calculated based on the three-phase input. Only applicable for functions which need residual voltage or current as input.
The analog channel is dedicated to the function. When the corresponding function is taken into use, other functions cannot use this analog channel any more. The other functions can be set to use calculated values instead of physical measured value or select an alternative operation mode not requiring this physical measured channel. However, some functions might not have such operation modes and might become unusable in the configuration. All functions marked to use the same HW channel under the same column should be checked to make sure the functions work.

Functional diagrams
The functional diagrams describe the default input, output, programmable LED, and function-to-function connections of default configuration. The default connections can be viewed and changed with PCM600 according to the application requirements, if necessary.
The analog channels, measurements from CTs and VTs have fixed connections to the different function blocks inside the relay. Exceptions from this rule are the 12 analog channels available for the disturbance recorder function. These channels are freely selectable and a part of the disturbance recorder’s parameter settings.
The signal marked with 3I represents the three phase currents from the terminal side of the motor. The signal marked with 3IB represents the three phase currents from the neutral side of the motor. The signal Io represents the measured residual current, fed from either residually connected CTs or an external core balance CT or neutral CT, depending on application.
The signal marked with 3U represents the three phase system voltages on the bus.
These inputs are connected in Delta, which are typically fed from open-delta (V
REM620
Application Manual
1MRS757655 E REM620 default configurations
REM620
Application Manual connected) VTs from the system. When star connected VT is available in the system, the VT inputs in the IED are star connected and configuration setting is suitably changed. In addition, the signal marked with Uo represents the measured residual voltage via open-delta connected VTs.
The signal marked Usyn is measured from the VT on the terminal side of the motor.
This signal is used to check synchronizing.
The relay offers six different settings groups which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in the relay.
There are 16 programmable push buttons offered in the front panel of the unit. The relay offers six different settings groups which can be set based on individual needs.
Each group can then, be activated or deactivated by using a programmable button.
In addition to this, the programmable button can be also used for emergency start and emergency stop, manual trigger of disturbance recorder, master trip lockout reset, circuit breaker control interlocking bypass, restart inhibit, and so on.

Figure 23: Overcurrent and motor jam protection
Seven overcurrent stages in total are offered for overcurrent and short-circuit protection. Three stages are for directional functionality DPHxPDOC, while the others are only for non-directional overcurrent protection PHxPTOC.
PHLPTOC1 can be used for overcurrent protection, and PHIPTOC1 for the shortcircuit protection. The operation of PHIPTOC1 is not blocked as default by any functionality and it should be set over the motor start current level to avoid unnecessary operation.
The motor load jam protection JAMPTOC1 is used for protecting the motor in stall or mechanical jam situations during the running state. The motor jam protection function JAMPTOC1 is blocked by the motor start-up protection function.
The OPERATE outputs are connected to the Master Trip. The OPERATE outputs are also connected to the alarm LED 4, except for PHIPTOC1, which is connected to the alarm LED 3. LED 3 is used for short-circuit protection alarm indication; LED 4 is used for combined protection alarm indication, including overcurrent protection, earth-fault protection, phase unbalance protection, voltage protection, motor jam protection, loss of load protection and frequency protection.

Figure 24: Earth-fault protection
Three stage non-directional earth-fault protection EFxPTOC is offered to detect phase-to-earth faults that may be a result of, for example, insulation ageing. In addition, there are two directional protection stages DEFxPDEF which can also be used as non-directional earth-fault protection without residual voltage requirement. However, the residual voltage can help to detect earth faults at a low fault current level selectively and to discriminate the apparent residual current caused, for example, by partial current transformer saturation at motor start-up.
The earth-fault protection is blocked when the short-circuit protection PHIPTOC1 is started. The OPERATE outputs of the earth-fault protection functions are connected to the Master Trip and alarm LED 4.

Figure 28: Emergency start and restart inhibit
The emergency start function ESMGAPC1 allows motor start-ups, although the calculated thermal level or cumulative start-up time counter is blocking the restart.
The emergency start is enabled for ten minutes after the selected binary input
X105- BI2 is energized. On the rising edge of the emergency start signal, various events occur.
• The calculated thermal level in MPTTR1 is set slightly below the restart inhibit level to allow at least one motor start-up
• The value of the cumulative start-up time counter STTPMSU1 is set slightly below the set restart inhibit value to allow at least one motor start-up
• Set start value of the MAPGAPC1 function is increased (or decreased) depending on the Start value Add setting
• Alarm LED 10 is activated
A new emergency start cannot be made until the emergency start signal has been reset and the emergency start time of ten 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 breaker when the machine is overloaded, the emergency start request removes this blocking and enables the restarting of the motor. The OPERATE output of MPTTR1 is connected to alarm LED 5, which is used for thermal overload protection alarm indication. The ALARM output of MPTTR1 is connected to output X115-SO3 via generic timer TPGAPC2.
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

Figure 29: Motor startup supervision
With the motor start-up supervision function STTPMSU1, the starting of the motor is supervised by monitoring three-phase currents or the status of the energizing circuit breaker of the motor.
When the emergency start request is activated by ESMGAPC1 and STTPMSU1 is in lockout state, the lockout LOCK_START is deactivated and emergency start is available. The MOT_START output of STTPMSU1 is connected to output X115-SO1 via generic timer TPGAPC2.
The motor running time counter MDSOPT1 provides history data since last commissioning. The counter counts the total number of motor running hours and is incremented when the energizing circuit breaker is closed. The alarm of the runtime counter is connected to alarm LED 9. LED 9 is used for general supervision of trip circuit, current measurement circuit, voltage measurement circuit and motor operation time.

Figure 30: Phase unbalance and loss of load 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 phase reversal protection PREVPTOC1 is based on the calculated negative phase-sequence current. It detects too high NPS current values during motor startup, caused by incorrectly connected phases, which in turn causes the motor to rotate in the opposite direction.
The negative-sequence protection and phase reversal protection are blocked if the current circuit supervision detects failure in the current measuring circuit. The binary input X105-BI1, which indicates the motor rotation direction, is also used to block these functions by default.
Two stages LOFLPTUC1 and LOFLPTUC2 are offered for loss of load situation protection. The loss of load situation can happen, for example, if there is damaged pump or a broken conveyor.
The OPERATE outputs of above protections are connected to the Master Trip and alarm LED 4.

It is assumed that there is no external resistor in the circuit breaker tripping coil circuit connected in parallel with the circuit breaker normally open auxiliary contact.
Parameters for TCSSCBR1 need to be properly set.
Failures in current measuring circuits are detected by CCSPVC1. When a failure is detected, blocking signal is activated in current protection functions that are measuring calculated sequence component currents, and unnecessary operation can be avoided. The alarm signal is also connected to the alarm LED 9.
The fuse failure supervision SEQSPVC1 detects failures in voltage measurement circuits. Failures, such as an open miniature circuit breaker, are detected and the alarm is also connected to the alarm LED 9.

Figure 37: Synchronism and energizing check
The main purpose of the synchronism and energizing check SECRSYN1 is to provide control over the closing of the circuit breakers in power networks and prevent the closing if the conditions for synchronism are not fulfilled. The energizing function allows closing, for example, when one side of the breaker is dead.
SECRSYN1 measures the bus and motor terminal voltages and compares them to set conditions. When all the measured quantities are within set limits, the SYNC_OK output is activated for allowing closing or closing the circuit breaker. The SYNC_OK output signal is connected to the ENA_CLOSE input of CBXCBR1 through control.
To ensure the validity of the measured voltages on both sides, Bus MCB Open

There are two types of disconnector and earthing switch blocks available.
DCSXSWI1...4 and ESSXSWI1...3 are status-only type, and DCXSWI1...4 and ESXSWI1…
3 are controllable type. By default, the status-only blocks are connected in the standard configuration logic. If a controllable operation is preferred, the controllable type of disconnector and earthing switch blocks can be used, instead of the status-only type. The connection and configuration of the control blocks can be made using PCM600.
The binary inputs 1 and 2 of the card X130 are used for busbar disconnector 1
DCSXSWI1 position indication. The binary inputs 3 and 4 of the card X130 are used for busbar disconnector 2 DCSXSWI2 position indication.

The circuit breaker closing is enabled when the ENA_CLOSE input is activated. The input can be activated by the configuration logic, which is a combination of the position statuses of related primary equipment (disconnector and earthing switch), the condition of the circuit breaker (CB gas pressure alarm, CB spring charged), and the Master Trip logics. The OKPOS output from the DCSXSWI block defines if the disconnector is definitely either open or close. This, together with non-active trip signal activates the ENA_CLOSE signal to the circuit breaker control function block.
The open operation is always enabled.
The circuit breaker closing is blocked when the BKL_CLOSE input is activated, which is connected to motor restart inhibit logic. When all conditions of the circuit breaker closing are fulfilled, the CLOSE_ENAD output of the CBXCBR1 is activated and PO1 output X100-PO1 is closed.
Emergency stop signal to AU_OPEN input of CBXCBR1 via MVGAPC1 is used to open the breaker by one push button through SPCGAPC1_O8 or by a binary input X105-
BI5. Emergency start signal to AU_CLOSE input of CBXCBR1 via MVGAPC1 is used to

1MRS757655 E close the breaker by one push button through SPCGAPC1_O16 or by a binary input
X105-BI6.
One push button can be used through SPCGAPC1_O11, which is connected to
SYNC_ITL_BYP input of the CBXCBR1, to ignore the status of ENA_CLOSE input
However, the BKL_CLOSE input signals are not bypassed with the interlocking bypass functionality as they always have a higher priority.
If the ENA_CLOSE signal is completely removed from the breaker control function block CBXCBR1 with PCM600, the function assumes that the breaker-closing commands are allowed continuously.
The circuit breaker condition monitoring function SSCBR1 supervises the circuit breaker status based on the binary input information connected and the measured current levels. SSCBR introduces various supervision methods. The corresponding supervision alarm signals are routed to LED 8.

Application configuration of SMV receiver
This chapter describes how to configure configuration A as an SMV receiver. For overall information about SMV engineering, see the IEC
61850 engineering guide.
This configuration includes three TVTR function blocks. If no SMV receiver is defined, all TVTRs receive voltage inputs from physical channels and provide the value to different functions.

The SMV receiver application configuration is done with the Application
Configuration tool in PCM600. Which physical voltage input channel is replaced by sample value voltage can be defined by connecting the SMVRCV output to different
TVTR function inputs.
The IEC 61850-9-2 LE stream always contains UL1, UL2, UL3 and Uo. Thus, when the IEDs are used as senders, and the three phase-tophase voltages and Uo are connected to the hardware channels, the three phase-to-earth voltages are calculated from the input and sent through
IEC 61850-9-2 LE.
The IEC 61850-9-2 LE configuration has to be done only according to the examples in this section, otherwise an engineering failure might follow.

Default configuration B
Applications
The default configuration is designed for motor protection with current and voltage based protection and measurement functions and is mainly intended for comprehensive protection and control of circuit breaker controlled asynchronous motors. With minor modifications this default configuration can be applied also for contactor controlled motors. There is also an option for mA/RTD measurement and protection.
The IED with a default configuration is delivered from the factory with default settings and parameters. The end-user flexibility for incoming, outgoing and internal signal designation within the IED enables this configuration to be further adapted to different primary circuit layouts and the related functionality needs by modifying the internal functionality using PCM600.

in this configuration are listed in Table 31 . Meaning of the symbols is explained in
Table 30: Explanations of symbols in the physical analog channel table
Symbol Description x
C
D
The analog channel is assigned to the function by default.
The function can be set to use residual voltage or current calculated based on the three-phase input. Only applicable for functions which need residual voltage or current as input.
The analog channel is dedicated to the function. When the corresponding function is taken into use, other functions cannot use this analog channel any more.
The other functions can be set to use calculated values instead of physical measured value or select an alternative operation mode not requiring this physical measured channel. However, some functions might not have such operation modes and might become unusable in the configuration. All functions marked to use the same HW channel under the same column should be checked to make sure the functions work.

Functional diagrams
The functional diagrams describe the default input, output, programmable LED, and function-to-function connections of default configuration. The default connections can be viewed and changed with PCM600 according to the application requirements, if necessary.
The analog channels, measurements from CTs and VTs have fixed connections towards the different function blocks inside the relay's default configuration.
Exceptions from this rule are the 12 analog channels available for the disturbance recorder function. These channels are freely selectable and a part of the disturbance recorder’s parameter settings.
The phase currents to the relay are fed from Rogowski or combi sensors. The residual current to the relay is fed from either residually connected CTs, an external core balance CT, neutral CT or internally calculated. The phase voltages to the relay are fed from combi sensors. The residual voltage is internally calculated.
The relay offers six different setting groups which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in the relay.
As there is no dedicated physical channel to measure the residual voltage, for all functions which need the residual voltage as input, it is forced to use the calculated residual voltage.
There are 16 programmable push buttons offered in the front panel of the unit. The relay offers six different setting groups which can be set based on individual needs.
Each group can then be activated or deactivated by using a programmable button.
In addition to this, the programmable button can also be used, for example, for the manual trigger of disturbance recorder, enabling/disabling the autoreclosing function, circuit breaker control interlocking bypass or master trip lockout reset.

Seven overcurrent stages in total are offered for overcurrent and short-circuit protection. Three stages are for directional functionality DPHxPDOC, while the others are only for non-directional overcurrent protection PHxPTOC.
PHLPTOC1 can be used for overcurrent protection and PHIPTOC1 for the shortcircuit protection. The operation of PHIPTOC1 is not blocked as default by any functionality and it should be set over the motor start current level to avoid unnecessary operation.
The motor load jam protection JAMPTOC1 is used for protecting the motor in stall or mechanical jam situations during the running state. The motor jam protection function JAMPTOC1 is blocked by the motor start-up protection function.
The OPERATE outputs are connected to the Master Trip. The OPERATE outputs are also connected to the alarm LED 4, except for PHIPTOC1, which is connected to the alarm LED 1. LED 1 is used for short-circuit protection alarm indication, and LED 4 is used for combined protection alarm indication, including overcurrent protection,

Figure 61: Earth-fault protection
Three stage non-directional earth-fault protection EFxPTOC are offered to detect phase-to-earth faults that may be a result of, for example, insulation ageing. In addition, there are two directional protection stages DEFxPDEF which can also be used as non-directional earth-fault protection without residual voltage requirement. However, the residual voltage can help to detect earth faults at a low fault current level selectively and to discriminate the apparent residual current caused, for example, by partial current transformer saturation at motor start-up.
The earth-fault protection is blocked when the short-circuit protection PHIPTOC1 is started. The OPERATE outputs of the earth-fault protection functions are connected to the Master Trip and alarm LED 2.

Figure 65: Emergency start and restart inhibit
The emergency start function ESMGAPC1 allows motor start-ups although the calculated thermal level or cumulative start-up time counter is blocking the restart.
The emergency start is enabled for ten minutes after the selected binary input
X105- BI2 is energized. On the rising edge of the emergency start signal, various events occur.
• The calculated thermal level in MPTTR1 is set slightly below the restart inhibit level to allow at least one motor start-up
• The value of the cumulative start-up time counter STTPMSU1 is set slightly below the set restart inhibit value to allow at least one motor start-up
• Alarm LED 10 is activated
A new emergency start cannot be made until the emergency start signal has been reset and the emergency start time of ten 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 breaker when the machine is overloaded, the emergency start request removes this blocking and enables the restarting of the motor. The OPERATE output of MPTTR1 is connected to alarm LED 5, which is used for thermal overload protection alarm indication. The ALARM output of MPTTR1 is connected to output X115-SO3 via generic timer TPGAPC2.
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 alarm
LED 6 is used for restart inhibit alarm indication.
The restart inhibit is also activated when one of the conditions is met.

Figure 66: Motor start-up supervision
With the motor start-up supervision function STTPMSU1 the starting of the motor is supervised by monitoring three-phase currents or the status of the energizing circuit breaker of the motor.
When the emergency start request is activated by ESMGAPC1 and STTPMSU1 is in lockout state, the lockout LOCK_START is deactivated and emergency starting is available. The MOT_START output of STTPMSU1 is connected to output X115-SO1 via generic timer TPGAPC2.
The motor running time counter MDSOPT1 provides history data since last commissioning. The counter counts the total number of motor running hours and is incremented when the energizing circuit breaker is closed. The alarm of the runtime counter is connected to alarm LED 9. LED 9 is used for general supervision of trip circuit, current measurement circuit, voltage measurement circuit and motor operation time.

Figure 67: Phase unbalance and loss of load protection
Two negative-sequence overcurrent stages MNSPTOC1/2 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 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.
The negative-sequence protection and phase reversal protection are blocked if the current circuit supervision detects failure in the current measuring circuit. The binary input X105-BI1, which indicates the motor rotation direction, is also used to block these functions by default.
Two stages LOFLPTUC1/2 are offered for loss of load situation protection. The loss of load situation can happen, for example, if there is damaged pump or a broken conveyor.
The OPERATE outputs of above protections are connected to the Master Trip and alarm LED 4.

There are two types of disconnector and earthing switch blocks available.
DCSXSWI1...4 and ESSXSWI1...3 are status only type, and DCXSWI1...4 and ESXSWI1…
3 are controllable type. By default, the status only blocks are connected in standard configuration logic. If controllable operation is preferred, the controllable type of disconnector and earthing switch blocks can be used instead of the status only type. The connection and configuration of the control blocks can be done using
PCM600.
The binary inputs 1 and 2 of the card X130 are used for busbar disconnector 1
DCSXSWI1 position indication. The binary inputs 3 and 4 of the card X130 are used for busbar disconnector 2 DCSXSWI2 position indication.

The circuit breaker closing is enabled when the ENA_CLOSE input is activated. The input can be activated by the configuration logic, which is a combination of the position statuses of related primary equipment (disconnector and earthing switch), the condition of the circuit breaker (CB gas pressure alarm, CB spring charged), and the Master Trip logics. The OKPOS output from the DCSXSWI block defines if the disconnector is definitely either open or close. This, together with non-active trip signal activates the ENA_CLOSE signal to the circuit breaker control function block.
The open operation is always enabled.
The circuit breaker closing is blocked when the BKL_CLOSE input is activated, which is connected to motor restart inhibit logic. When all conditions of the circuit breaker closing are fulfilled, the CLOSE_ENAD output of the CBXCBR1 is activated and PO1 output X100-PO1 is closed.
Emergency stop signal to AU_OPEN input of CBXCBR1 via MVGAPC1 is used to open the breaker by one push button through SPCGAPC1_O8 or by a binary input X105-
BI5. Emergency start signal to AU_CLOSE input of CBXCBR1 via MVGAPC1 is used to close the breaker by one push button through SPCGAPC1_O16 or by a binary input
X105-BI6.
One push button can be used through SPCGAPC1_O11, which is connected to
SYNC_ITL_BYP input of CBXCBR1, to ignore the status of ENA_CLOSE input.
However, the BLK_CLOSE input signals is not bypassed with the interlocking bypass functionality as they always have the higher priority.
If the ENA_CLOSE signal is completely removed from the breaker control function block CBXCBR1 with PCM600, the function assumes that the breaker close commands are allowed continuously.
The circuit breaker condition monitoring function SSCBR1 supervises the circuit breaker status based on the binary input information connected and measured current levels. The function introduces various supervision methods. The corresponding supervision alarm signals are routed to LED 8.

These functions can be used in the common point of coupling of utility grid and distributed energy resource, depending on the selected setting to disconnect the distributed power generation to support utility grid stability and to detect islanding. They can also be used to disconnect the distributed generator from common point of coupling. A failure in the voltage measuring circuit detected by the fuse failure function can be used to block
LVRTPTUV1…3 and DQPTUV1 protection. These interconnection functions can be engineered to work together with basic functions in relay default configuration to cover different needs placed for relay operation in different grid codes.

This configuration includes two TVTR function blocks. If no SMV receiver is defined,
ULTVTR1 receives three phase voltage inputs from the sensor and provides the value to different functions. ULTVTR2 is dedicated for IEC 61850-9-2 LE receiving only. SECRSYN1 and VAMMXU2 cannot be used if a IEC 61850-9-2 LE sample value is not configured to be received by ULTVTR2.

The SMV receiver application configuration is done with the Application
Configuration tool in PCM600. Which physical voltage input channel is replaced by sample value voltage can be defined by connecting the SMVRCV output to different
TVTR function inputs.
The IEC 61850-9-2 LE stream always contains UL1, UL2, UL3 and Uo. Thus, when the IEDs are used as senders, and the three phase-tophase voltages and the residual voltage are connected to the hardware channels, the three phase-to-earth voltages are calculated from the input and sent through IEC 61850-9-2 LE.
The IEC 61850-9-2 LE configuration has to be done only according to the examples in this section, otherwise an engineering failure might follow.

When SMVRCV is connected to ULTVTR1 in the Application Configuration tool,
ULTVTR1 is disconnected from the physical channels U1, U2 and U3 and uses three phase voltages from the received IEC 61850-9-2 LE sample value. All functions which have 3U input begin working with the IEC 61850-9-2 LE sample value.
All three signals UL1, UL2 and UL3 must be connected between SMVRCV and ULTVTR1 in the Application Configuration tool.
ULTVTR2, SECRSYN1 and VAMMUX2 cannot be used in this configuration.
