Section 2 REV615 overview

2.1 Overview

REV615 is a dedicated capacitor bank relay designed for the protection, control,measurement and supervision of capacitor banks used for compensation of reactivepower in utility substations and industrial power systems. REV615 can also be usedfor protection of harmonic filter circuits, if the highest significant harmoniccomponent is the 11th. REV615 is a member of ABB’s Relion® product family andpart of its 615 protection and control product series. The 615 series relays arecharacterized by their compactness and withdrawable-unit design.

Re-engineered from the ground up, the 615 series has been designed to unleash the fullpotential of the IEC 61850 standard for communication and interoperability betweensubstation automation devices.

The relay provides main protection for single star, double star, and H-bridgeconnected capacitor banks and harmonic filters in distribution networks.

Depending on the chosen standard configuration, the relay is adapted for theprotection of H-bridge connected or double star connected shunt capacitor banks.Once the standard configuration relay has been given the application-specific settings,it can directly be put into service.

The 615 series relays support a range of communication protocols including IEC61850 with Edition 2 support, process bus according to IEC 61850-9-2 LE, IEC60870-5-103 and Modbus®. Profibus DPV1 communication protocol is supported byusing the protocol converter SPA-ZC 302.

2.4.2 LEDs

The LHMI includes three protection indicators above the display: Ready, Start andTrip.

There are 11 matrix programmable LEDs on front of the LHMI. The LEDs can beconfigured with PCM600 and the operation mode can be selected with the LHMI,WHMI or PCM600.

2.4.3 Keypad

The LHMI keypad contains push buttons which are used to navigate in different viewsor menus. With the push buttons you can give open or close commands to objects inthe primary circuit, for example, a circuit breaker, a contactor or a disconnector. Thepush buttons are also used to acknowledge alarms, reset indications, provide help andswitch between local and remote control mode.

Figure 4: LHMI keypad with object control, navigation and command pushbuttons and RJ-45 communication port

2.5 Web HMI

The WHMI allows secure access to the protection relay via a Web browser. When theSecure Communication parameter in the protection relay is activated, the Web serveris forced to take a secured (HTTPS) connection to WHMI using TLS encryption.TheWHMI is verified with Internet Explorer 8.0, 9.0, 10.0 and 11.0.

WHMI is disabled by default.

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• Report summary

The menu tree structure on the WHMI is almost identical to the one on the LHMI.

GUID-38AF6905-4903-4C61-B22C-8509D99398E0 V1 EN

Figure 5: Example view of the WHMI

The WHMI can be accessed locally and remotely.

• Locally by connecting the laptop to the protection relay via the frontcommunication port.

• Remotely over LAN/WAN.



2.6 Authorization

Four user categories have been predefined for the LHMI and the WHMI, each withdifferent rights and default passwords.

The default passwords in the protection relay delivered from the factory can bechanged with Administrator user rights.

User authorization is disabled by default for LHMI but WHMI alwaysuses authorization.

ENGINEER • Changing settings• Clearing event list• Clearing disturbance records• Changing system settings such as IP address, serial baud rate or

disturbance recorder settings• Setting the protection relay to test mode• Selecting language

ADMINISTRATOR • All listed above• Changing password• Factory default activation

For user authorization for PCM600, see PCM600 documentation.

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.



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.

PCM600 Event Viewer can be used to view the audit trail events and process relatedevents. Audit trail events are visible through dedicated Security events view. Sinceonly 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 listtogether with process related events.

To expose the audit trail events through Event list, define theAuthority logging level parameter via Configuration/Authorization/Security. This exposes audit trail events to all users.

The protection relay supports a range of communication protocols including IEC61850, IEC 61850-9-2 LE, IEC 60870-5-103 and Modbus®. 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 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.

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 REV615 standard configurations

3.1 Standard configurations

REV615 is available with one standard configuration. 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 REV615 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 some



initially 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 Standard configuration B

3.3.1 Applications

The standard configuration offers three phase overload protection, unbalanceprotection with compensation for natural unbalance and switching resonanceprotection for capacitor banks. An integrated undercurrent function in the overloadprotection function block detects the disconnection of a capacitor bank and inhibitsthe closing of the circuit breaker as long as the capacitor bank is still partiallydischarged. A three-phase thermal overload protection is available and can be used forthe thermal protection of the reactors and resistors in the harmonic filter circuits.

The standard configuration B is pre-configured for double-Y connected capacitorbanks. A three-phase current unbalance protection is used for unbalance protection.

The second and third stage of the residual voltage protection in the standardconfiguration B can be used as voltage based unbalance protection mainly for singlestar-connected capacitor banks, with unearthed star point. A dedicated voltage inputUob is used for this purpose. This functionality needs to be configured before it canbe taken into use.

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.

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 capacitor phase currents as well as capacitor unbalance current to the protectionrelay are fed from a current transformer. The residual current to the protection relay isfed either from residually connected current transformers, an external core balanceCT, neutral CT or internally calculated.

The capacitor phase voltages to the protection relay are fed from a voltagetransformer. The residual voltage to the protection relay is fed either from residuallyconnected voltage transformers, an open delta connected VT or internally calculated.

The protection relay offers six different setting groups which can be set based on theindividual 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.

Four non-directional overcurrent stages are offered for capacitor overcurrent andshort-circuit protection.

The circuit breaker failure protection CCBRBRF1 is initiated via the START input bynumber of different protection functions available in the protection relay. The circuitbreaker failure protection function offers different operating modes associated withthe circuit breaker position and the measured phase and residual currents.

The circuit breaker failure protection function has two operating outputs: TRRET andTRBU. The TRRET operate output is used for retripping its own breaker throughTRPPTRC2_TRIP. The TRBU output is used to give a backup trip to the breakerfeeding upstream. For this purpose, the TRBU operate output signal is connected to thebinary output X100:PO2.

Thisoutput, together with the open earth-switch and non-active trip signals, activates theclose-enable signal to the circuit-breaker control function block. The open operationfor circuit breaker is always enabled.

The SYNC_ITL_BYP input can be used, for example, to always enable the closing ofthe circuit breaker when the circuit breaker truck is in the test position, despite theinterlocking conditions being active when the circuit breaker truck is closed in serviceposition.

Section 4 Requirements for measurementtransformers

4.1 Current transformers

4.1.1 Current transformer requirements for overcurrent protection

For reliable and correct operation of the overcurrent protection, the CT has to bechosen carefully. The distortion of the secondary current of a saturated CT mayendanger the operation, selectivity, and co-ordination of protection. However, whenthe 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 thenetwork fault current magnitude, desired protection objectives, and the actual CTburden. The protection settings of the protection relay should be defined in accordancewith the CT performance as well as other factors.

4.1.1.1 Current transformer accuracy class and accuracy limit factor

The rated accuracy limit factor (Fn) is the ratio of the rated accuracy limit primarycurrent to the rated primary current. For example, a protective current transformer oftype 5P10 has the accuracy class 5P and the accuracy limit factor 10. For protectivecurrent transformers, the accuracy class is designed by the highest permissiblepercentage composite error at the rated accuracy limit primary current prescribed forthe accuracy class concerned, followed by the letter "P" (meaning protection).

Table 17: Limits of errors according to IEC 60044-1 for protective current transformers

Accuracy class Current error atrated primarycurrent (%)

Phase displacement at rated primarycurrent

Composite error atrated accuracy limitprimary current (%)minutes centiradians

5P ±1 ±60 ±1.8 5

10P ±3 - - 10

The accuracy classes 5P and 10P are both suitable for non-directional overcurrentprotection. The 5P class provides a better accuracy. This should be noted also if thereare accuracy requirements for the metering functions (current metering, powermetering, and so on) of the protection relay.

The CT accuracy primary limit current describes the highest fault current magnitudeat which the CT fulfils the specified accuracy. Beyond this level, the secondary current

1MRS758955 A Section 4Requirements for measurement transformers


of the CT is distorted and it might have severe effects on the performance of theprotection relay.

In practise, the actual accuracy limit factor (Fa) differs from the rated accuracy limitfactor (Fn) and is proportional to the ratio of the rated CT burden and the actual CTburden.

The actual accuracy limit factor is calculated using the formula:

F FS S

S Sa n

in n

in

≈ ×

+

+

A071141 V1 EN

Fn the accuracy limit factor with the nominal external burden Sn

Sin the internal secondary burden of the CT

S the actual external burden

4.1.1.2 Non-directional overcurrent protection

The current transformer selectionNon-directional overcurrent protection does not set high requirements on the accuracyclass or on the actual accuracy limit factor (Fa) of the CTs. It is, however,recommended to select a CT with Fa of at least 20.

The nominal primary current I1n should be chosen in such a way that the thermal anddynamic strength of the current measuring input of the protection relay is notexceeded. This is always fulfilled when

I1n > Ikmax / 100,

Ikmax is the highest fault current.

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

Recommended start current settingsIf Ikmin is the lowest primary current at which the highest set overcurrent stage is tooperate, the start current should be set using the formula:

Current start value < 0.7 × (Ikmin / I1n)

I1n is the nominal primary current of the CT.

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

Section 4 1MRS758955 ARequirements for measurement transformers


The adequate performance of the CT should be checked when the setting of the highset stage overcurrent protection is defined. The operate time delay caused by the CTsaturation is typically small enough when the overcurrent setting is noticeably lowerthan Fa.

When defining the setting values for the low set stages, the saturation of the CT doesnot need to be taken into account and the start current setting is simply according to theformula.

Delay in operation caused by saturation of current transformersThe saturation of CT may cause a delayed protection relay operation. To ensure thetime selectivity, the delay must be taken into account when setting the operate timesof successive protection relays.

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

With inverse time mode of operation, the delay should always be considered as beingas 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 ACcomponent of the fault current should not saturate the CT less than 20 times thestarting current. Otherwise, the inverse operation time can be further prolonged.Therefore, the accuracy limit factor Fa should be chosen using the formula:

Fa > 20 × Current start value / I1n

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

4.1.1.3 Example for non-directional overcurrent protection

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

1MRS758955 A Section 4Requirements for measurement transformers


A071142 V1 EN

Figure 64: Example of three-stage overcurrent protection

The maximum three-phase fault current is 41.7 kA and the minimum three-phase shortcircuit current is 22.8 kA. The actual accuracy limit factor of the CT is calculated tobe 59.

The start current setting for low-set stage (3I>) is selected to be about twice thenominal current of the cable. The operate time is selected so that it is selective with thenext protection relay (not visible in Figure 64). The settings for the high-set stage andinstantaneous stage are defined also so that grading is ensured with the downstreamprotection. In addition, the start current settings have to be defined so that theprotection relay operates with the minimum fault current and it does not operate withthe maximum load current. The settings for all three stages are as in Figure 64.

For the application point of view, the suitable setting for instantaneous stage (I>>>) inthis example is 3 500 A (5.83 × I2n). I2n is the 1.2 multiple with nominal primarycurrent of the CT. For the CT characteristics point of view, the criteria given by thecurrent transformer selection formula is fulfilled and also the protection relay settingis considerably below the Fa. In this application, the CT rated burden could have beenselected much lower than 10 VA for economical reasons.
