2.6.1 Audit trail
The protection relay offers a large set of event-logging functions. Critical system andprotection relay security-related events are logged to a separate nonvolatile audit trailfor the administrator.
Audit trail is a chronological record of system activities that allows the reconstructionand examination of the sequence of system and security-related events and changes inthe protection relay. Both audit trail events and process related events can beexamined and analyzed in a consistent method with the help of Event List in LHMIand WHMI and Event Viewer in PCM600.
Section 2 1MRS758128 BREU615 overview
16 REU615Application Manual
-
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 audittrail and event list work according to the FIFO principle. Nonvolatile memory is basedon a memory type which does not need battery backup nor regular component changeto maintain the memory storage.
Audit trail events related to user authorization (login, logout, violation remote andviolation local) are defined according to the selected set of requirements from IEEE1686. The logging is based on predefined user names or user categories. The user audittrail events are accessible with IEC 61850-8-1, PCM600, LHMI and WHMI.

2.7 Communication
The protection relay supports a range of communication protocols including IEC61850, IEC 61850-9-2 LE, IEC 60870-5-103 and Modbus®. Profibus DPV1
Section 2 1MRS758128 BREU615 overview

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 betweenthe protection relays, is only enabled by the IEC 61850 communication protocol.
The IEC 61850 communication implementation supports all monitoring and controlfunctions. Additionally, parameter settings, disturbance recordings and fault recordscan be accessed using the IEC 61850 protocol. Disturbance recordings are availableto any Ethernet-based application in the IEC 60255-24 standard COMTRADE fileformat. 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 issupported. Furthermore, the protection relay supports sending and receiving of analogvalues using GOOSE messaging. The protection relay meets the GOOSEperformance requirements for tripping applications in distribution substations, asdefined by the IEC 61850 standard.
The protection relay can support five simultaneous clients. If PCM600 reserves oneclient connection, only four client connections are left, for example, for IEC 61850and Modbus.
All communication connectors, except for the front port connector, are placed onintegrated optional communication modules. The protection relay can be connected toEthernet-based communication systems via the RJ-45 connector (100Base-TX) or thefiber-optic LC connector (100Base-FX).
2.7.1 Self-healing Ethernet ring
For the correct operation of self-healing loop topology, it is essential that the externalswitches in the network support the RSTP protocol and that it is enabled in theswitches. Otherwise, connecting the loop topology can cause problems to thenetwork. 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 link-up/link-down events can cause temporary breaks in communication. For a betterperformance of the self-healing loop, it is recommended that the external switchfurthest 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 linksof the protection relay loop can be attached to the same external switch or to twoadjacent external switches. A self-healing Ethernet ring requires a communicationmodule 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 30protection relays. If more than 30 protection relays are to beconnected, it is recommended that the network is split into severalrings with no more than 30 protection relays per ring. Each protectionrelay has a 50-μs store-and-forward delay, and to fulfil theperformance requirements for fast horizontal communication, thering size is limited to 30 protection relays.
2.7.2 Ethernet redundancy
IEC 61850 specifies a network redundancy scheme that improves the systemavailability for substation communication. It is based on two complementaryprotocols defined in the IEC 62439-3:2012 standard: parallel redundancy protocolPRP and high-availability seamless redundancy HSR protocol. Both protocols rely onthe duplication of all transmitted information via two Ethernet ports for one logicalnetwork connection. Therefore, both are able to overcome the failure of a link orswitch with a zero-switchover time, thus fulfilling the stringent real-timerequirements for the substation automation horizontal communication and timesynchronization.
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 cost-effective redundancy. Thus, each device incorporates a switch element that forwardsframes from port to port. The HSR/PRP option is available for all 615 series protectionrelays. However, RED615 supports this option only over fiber optics.

IEC 62439-3:2012 cancels and replaces the first edition published in2010. These standard versions are also referred to as IEC 62439-3Edition 1 and IEC 62439-3 Edition 2. The protection relay supportsIEC 62439-3:2012 and it is not compatible with IEC 62439-3:2010.
PRPEach PRP node, called a double attached node with PRP (DAN), is attached to twoindependent LANs operated in parallel. These parallel networks in PRP are calledLAN A and LAN B. The networks are completely separated to ensure failureindependence, and they can have different topologies. Both networks operate inparallel, thus providing zero-time recovery and continuous checking of redundancy toavoid communication failures. Non-PRP nodes, called single attached nodes (SANs),are either attached to one network only (and can therefore communicate only withDANs and SANs attached to the same network), or are attached through a redundancybox, 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 PRPnetworks, LAN A or LAN B, it is recommended to use a redundancy box device or anEthernet switch with similar functionality between the PRP network and SAN toremove additional PRP information from the Ethernet frames. In some cases, defaultPC workstation adapters are not able to handle the maximum-length Ethernet frameswith the PRP trailer.
There are different alternative ways to connect a laptop or a workstation as SAN to aPRP network.

• Via an external redundancy box (RedBox) or a switch capable of connecting toPRP 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
HSRHSR applies the PRP principle of parallel operation to a single ring, treating the twodirections 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 eachnode forwards the frames it receives, from one port to the other. When the originatingnode receives a frame sent to itself, it discards that to avoid loops; therefore, no ringprotocol 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 redundancybox.

2.7.3 Process bus
Process bus IEC 61850-9-2 defines the transmission of Sampled Measured Valueswithin the substation automation system. International Users Group created aguideline IEC 61850-9-2 LE that defines an application profile of IEC 61850-9-2 tofacilitate implementation and enable interoperability. Process bus is used fordistributing process data from the primary circuit to all process bus compatibledevices in the local network in a real-time manner. The data can then be processed byany protection relay to perform different protection, automation and control functions.

UniGear Digital switchgear concept relies on the process bus together with currentand voltage sensors. The process bus enables several advantages for the UniGearDigital like simplicity with reduced wiring, flexibility with data availability to alldevices, improved diagnostics and longer maintenance cycles.
With process bus the galvanic interpanel wiring for sharing busbar voltage value canbe replaced with Ethernet communication. Transmitting measurement samples overprocess bus brings also higher error detection because the signal transmission isautomatically supervised. Additional contribution to the higher availability is thepossibility to use redundant Ethernet network for transmitting SMV signals.

Figure 9: Process bus application of voltage sharing and synchrocheck
The 615 series supports IEC 61850 process bus with sampled values of analogcurrents and voltages. The measured values are transferred as sampled values usingthe IEC 61850-9-2 LE protocol which uses the same physical Ethernet network as theIEC 61850-8-1 station bus. The intended application for sampled values is sharing themeasured voltages from one 615 series protection relay to other devices with phasevoltage based functions and 9-2 support.
The 615 series protection relays with process bus based applications use IEEE 1588 v2Precision Time Protocol (PTP) according to IEEE C37.238-2011 Power Profile forhigh accuracy time synchronization. With IEEE 1588 v2, the cabling infrastructurerequirement is reduced by allowing time synchronization information to betransported over the same Ethernet network as the data communications.

The process bus option is available for all 615 series protection relays equipped withphase voltage inputs. Another requirement is a communication card with IEEE 1588v2 support (COM0031...COM0037). However, RED615 supports this option onlywith the communication card variant having fiber optic station bus ports. See the IEC61850 engineering guide for detailed system requirements and configuration details.
2.7.4 Secure communication
The protection relay supports secure communication for WHMI and file transferprotocol. If the Secure Communication parameter is activated, protocols require TLSbased encryption method support from the clients. In this case WHMI must beconnected from a Web browser using the HTTPS protocol and in case of file transferthe client must use FTPS.

Section 3 REU615 standard configurations
3.1 Standard configurations
REU615 is available with two standard configurations. The standard signalconfiguration can be altered by means of the signal matrix or the graphical applicationfunctionality of the Protection and Control IED Manager PCM600. Further, theapplication configuration functionality of 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 configurationcan be adapted to user-specific application requirements.
The relay is delivered from the factory with default connections described in thefunctional diagrams for binary inputs, binary outputs, function-to-functionconnections and alarm LEDs. Some of the supported functions in REU615 must beadded with the Application Configuration tool to be available in the Signal Matrix tooland in the relay. The positive measuring direction of directional protection functionsis towards the outgoing feeder.

3.1.1 Addition of control functions for primary devices and the useof binary inputs and outputs
If extra control functions intended for controllable primary devices are added to theconfiguration, additional binary inputs and/or outputs are needed to complement thestandard configuration.
If the number of inputs and/or outputs in a standard configuration is not sufficient, itis possible either to modify the chosen standard configuration in order to release somebinary inputs or binary outputs which have originally been configured for otherpurposes, or to integrate an external input/output module, for example RIO600, to theprotection relay.
The external I/O module’s binary inputs and outputs can be used for the less time-critical binary signals of the application. The integration enables releasing someinitially reserved binary inputs and outputs of the protection relay’s standardconfiguration.
The suitability of the protection relay’s binary outputs which have been selected forprimary device control should be carefully verified, for example make and carry andbreaking capacity. If the requirements for the primary device control circuit are notmet, using external auxiliary relays should be considered.

3.3.3 Functional diagrams
The functional diagrams describe the default input, output, alarm LED and function-to-function connections. The default connections can be viewed and changed withPCM600 according to the application requirements.
The analog channels have fixed connections to the different function blocks inside theprotection relay’s standard configuration. However, the 12 analog channels availablefor the disturbance recorder function are freely selectable as a part of the disturbancerecorder’s parameter settings.
The phase and bus voltages to the protection relay are fed from voltage transformer.The residual voltage to the protection relay is fed from either residually connectedVTs or an open delta connected VT or internally calculated.
The protection relay offers six different setting groups which can be set based onindividual needs. Each group can be activated or deactivated using the setting groupsettings available in the protection relay.
Depending on the communication protocol the required function block needs to beinstantiated in the configuration.
3.3.3.1 Functional diagrams for protection
The functional diagrams describe the protection relay's protection functionality indetail and according to the factory set default connections.
Three overvoltage and undervoltage protection stages PHPTOV and PHPTUV offerprotection against abnormal phase voltage conditions. The undervoltage protectionstage is blocked, if fuse failure is detected in voltage transformer. The information isavailable through the binary input X130:BI1.

The selectable underfrequency or overfrequency protection FRPFRQ preventsdamage to network components under unwanted frequency conditions. The functionalso contains a selectable rate of change of the frequency (gradient) protection todetect an increase or decrease in the fast power system frequency at an early stage.This can be used as an early indication of a disturbance in the system.

Five load-shedding and restoration stages are offered in the standard configuration.The load-shedding and restoration function LSHDPFRQ is capable of shedding loadbased on underfrequency and rate of change of frequency. The load that is shed duringthe frequency disturbance can be restored once the frequency is stabilized to thenormal level. The manual restore commands can be given through the binary inputs.In the configuration, two restore stages are implemented with manual restorecommand. Depending on application needs, it is possible to take other stages into use.

Three arc protection stages ARCSARC1...3 are included as optional functions. Thearc protection offers individual function blocks for three arc sensors that can beconnected to the protection relay. The arc protection in this standard configurationdetects an arc flash and supplies the information for the operating arc protection unit,which de-energizes the faulty area by opening the circuit breaker. For example, fastGOOSE communication is used to route the detected information to the circuitbreaker.
If the protection relay is ordered with high speed binary outputs, individual arcdetection from ARCSARC1...3 are connected to the dedicated high speed outputsX110:HSO1, X110:HSO2 and X110:HSO3.

phase non-directional overcurrent protection, three-phase under- and overvoltageprotection. The configuration also incorporates a thermal overload protectionfunction, which supervises the thermal stress of the transformer windings to preventpremature aging of the winding’s insulation.
The RTD/mA input module is optional in the configuration. While using the RTD/mAinput module, it is possible to have the tap changer position indication as an mA signal.Ambient temperature of the power transformer can be used in thermal protection andthe multi-purpose protection functions are also available. The multi-purposeprotection function enables protection based on analog values from the IEDsRTD/mA input module or from other IEDs using analog horizontal GOOSEmessaging.
The protection relay with a standard configuration is delivered from the factory withdefault settings and parameters. The end-user flexibility for incoming, outgoing andinternal signal designation within the protection relay enables this configuration to befurther adapted to different primary circuit layouts and the related functionality needsby modifying the internal functionality using PCM600.
