Section 2 REF615 overview

2.1 Overview

REF615 is a dedicated feeder IED (intelligent electronic device) designed for theprotection, control, measurement and supervision of utility substations and industrialpower systems. REF615 is a member of ABB’s Relion® product family and part of its615 protection and control product series. The 615 series IEDs are characterized bytheir compactness and withdrawable 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 IED provides main protection for overhead lines and cable feeders in distributionnetworks. The IED is also used as back-up protection in applications, where anindependent and redundant protection system is required.

Depending on the chosen standard configuration, the IED is adapted for the protectionof overhead line and cable feeders in isolated neutral, resistance earthed, compensatedand solidly earthed networks. Once the standard configuration IED has been given theapplication-specific settings, it can directly be put into service.

The 615 series IEDs support a range of communication protocols including IEC 61850with GOOSE messaging, Modbus® and DNP3.

2.7 Communication

The IED supports different communication protocols: IEC 61850, Modbus® and DNP3.0 Level 2 - all using TCP/IP. DNP3 and Modbus also support serial communication.Operational information and controls are available through these protocols. However,some communication functionality, for example, horizontal peer-to-peercommunication between the IEDs and parameters setting, is only enabled by the IEC61850 communication protocol.

The IEC 61850 communication implementation supports all monitoring and controlfunctions. Additionally, parameter setting and DFR records can be accessed using theIEC 61850 protocol. Oscillographic files are available to any Ethernet-basedapplication in the standard COMTRADE format. Further, the IED can send andreceive binary signals from other IEDs (so called horizontal communication) using theIEC61850-8-1 GOOSE profile, where the highest performance class with a total



transmission time of 3 ms is supported. The IED meets the GOOSE performancerequirements for tripping applications in distribution substations, as defined by the IEC61850 standard. The IED can simultaneously report events to five different clients onthe station bus.

All communication connectors, except for the front port connector, are placed onintegrated optional communication modules. The IED can be connected to Ethernet-based communication systems via the RJ-45 connector (100BASE-TX) or the fiber-optic LC connector (100BASE-FX). An optional serial interface is available forRS-232/RS-485 communication.



Section 3 REF615 variants

3.1 REF615 variant list

REF615 is intended for protection and control mainly in MV feeder applications. Theproduct has two standard configurations covering a wide range of primary circuitconfigurations in distribution networks based on different system grounding methods.

Some of the functions included in the IED's standard configurations are optional at thetime of placing the order. The description of standard configurations covers the fullfunctionality including options, presenting the functionality, flexibility and externalconnections of REF615 with a specific configuration as delivered from the factory.

3.2 Presentation of standard configurations

Functional diagramsThe functional diagrams describe the IED's functionality from the protection,measuring, condition monitoring, recording, control and interlocking perspective.Diagrams show the default functionality with simple symbol logics forming principlediagrams. The external connections to primary devices are also shown, stating thedefault connections to measuring transformers. The positive measuring direction istowards the outgoing feeder, away from the bus bar.

The functional diagrams are divided into sections with each section constituting onefunctional entity. The external connections are also divided into sections. Only therelevant connections for a particular functional entity are presented in each section.

Protection function blocks are part of the functional diagram. They are identified basedon their ANSI function number/acronym, but the IEC based symbol and the IEC 61850names are also included. Some function blocks are used several times in theconfiguration. To separate the blocks from each other, the IEC 61850 name and ANSIfunction number are appended with a running number, that is an instance number, fromone upwards. The IED’s internal functionality and the external connections areseparated with a dashed line presenting the IED’s physical casing.

1MAC109554 C Section 3REF615 variants


Signal MatrixWith Signal Matrix in PCM600 the user can modify the standard configurationaccording to the actual needs. The IED is delivered from the factory with defaultconnections described in the functional diagrams for BI's, BO's, function to functionconnections and alarm LEDs. Signal Matrix has a number of different page views,designated as follows:

• Binary input• Binary output• Functions

There are four IED variant-specific setting groups. Parameters can be set independentlyfor each setting group.

The active setting group (1...4) can be changed with a parameter. The active settinggroup can also be changed via a binary input if the binary input is enabled for this. Toenable the change of the active setting group via a binary input, connect a free binaryinput with PCM600 to the ActSG input of the SGCB-block.

Table 6: Binary input states and corresponding active setting groups

BI state Active setting groupOFF 1

3.3 Standard Configuration FA01: Current inputs only

3.3.1 ApplicationsThe standard configuration FA01 is meant for current inputs only. It is mainly intendedfor cable and overhead-line feeder applications in directly or resistance groundeddistribution networks.

The IED with this standard configuration is delivered from the factory with the defaultsettings and parameters. The end-user flexibility for incoming, outgoing and internalsignal designation within the IED enables this configuration to be further adapted todifferent primary circuit layouts and the related functionality needs by modifying theinternal functionality using PCM600. As a security measure, all functions except 51Pare disabled.

3.3.3 Functional diagramsThe functional diagrams describe the default input, output, alarm LED and function tofunction connections. The default connections can be viewed with the Signal Matrixtool and changed according to the application requirements, if necessary.

The analog channels, measurements from CTs, have fixed connections to the differentfunction blocks inside the IED’s standard configuration.

The analog channels are assigned to different functions as shown in the functionaldiagrams. The common signal marked with IA, IB, IC represents the three phasecurrents. The signal IG represents the measured ground current.



3.3.3.1 Functional diagrams for protection

The following functional diagrams describe the IED’s protection functionality in detailand according to the factory set default connections in the Signal Matrix tool.

Five overcurrent stages are offered for phase overcurrent and short-circuit protection.The inrush detection block’s (INR) output BLK2H provides the possibility to eitherblock the function or multiply the active settings for any of the shown protectionfunction blocks.

Figure 8: Phase overcurrent protection

The neutral overcurrent protections 51N, 50N-1/2 can be blocked by energizing thebinary input 1 (X120:1-2). Two negative sequence overcurrent stages (46-1 and 46-2)are included for phase unbalance protection along with a separate phase discontinuityprotection. The phase discontinuity protection (46PD) provides protection forinterruptions in the normal three-phase load supply, like in downed conductorsituations. Two separate cold load timers are provided with seconds and minutes



ranges to provide utmost flexibility in cold-load inrush protection. Any functions canbe selected to be blocked during the cold load timers pickup duration using the SignalMatrix tool.

All trip signals are connected to the Master Trip Logic and also to the alarm LEDs.

The breaker failure protection (50BF) is initiated via the pickup input by a number ofdifferent protection stages in the IED. The breaker failure protection function offersdifferent operating modes associated with circuit breaker position and the measuredphase and residual currents. The breaker failure protection has two operating outputs:TRRET and TRBU. The TRRET output is used for retripping its own breaker throughthe Master Trip. The TRBU output is used to give a back-up trip to the breakersassociated with the faulty breaker. For this purpose the TRBU trip output signal isconnected to output PO2 (X100: 8-9).

Figure 21: Circuit breaker control and interlocking

The ENA_CLOSE input, which enables closing the circuit breaker, in the breakercontrol function block 52-1, is a combination of the status of the Master Trip Logics.The open operation is always enabled.

If the ENA_CLOSE signal is completely removed from the breakercontrol function block 52-1 with the Signal Matrix tool, the functionassumes that the breaker close commands are allowed continuously.

The circuit-breaker condition monitoring function (52CM) supervises the circuitbreaker status based on the binary input information connected and measured currentlevels. The function introduces various supervision methods. The correspondingsupervision alarm signals are routed to LED 8.

The signal outputs from the IED are connected to give dedicated information onpickups and trips.

The autoreclosing function can be blocked with the INHIBIT_RECL input. As adefault, the operation of some selected protection functions are connected to this input.A control command to the circuit breaker, either local or remote, will also block theautoreclose function via the 52-1-selected signal.

The circuit breaker availability for the autoreclosure sequence is expressed with theCB_RDY input in 79. In the configuration, this signal is not connected to any of thebinary inputs. As a result, the function assumes that the breaker is available all the time.

Figure 28: High impedance fault detection

The sensitive earth-fault protection (50SEF) and high impedance fault detection (HIZ)provide protection against high impedance faults. If the load unbalance is high, 50SEFneeds to be set high to avoid misoperations which renders 50SEF ineffective for suchapplications. In those cases, HIZ can provide detection which would otherwise beundetected.

3.4 Standard configuration FA02: Current and voltageinputs

3.4.1 ApplicationsThe standard configuration FA02 is meant for voltage and current inputs, intended forcable and overhead-line feeder applications in directly or resistance groundeddistribution networks where directional application is a requirement.

The IED with this standard configuration is delivered from the factory with defaultsettings and parameters. The end-user flexibility for incoming, outgoing and internalsignal designation within the IED enables this configuration to be further adapted todifferent primary circuit layouts and the related functionality needs by modifying theinternal functionality using PCM600.



As a security measure, all functions except 51P are disabled.

3.4.3 Functional diagramsThe functional diagrams describe the default input, output, alarm LED and function tofunction connections. The default connections can be viewed with the Signal Matrixtool and changed according to the application requirements, if necessary.

The analog channels, measurements from CTs, have fixed connections to the differentfunction blocks inside the IED’s standard configuration.

The analog channels are assigned to different functions as shown in the functionaldiagrams. The common signal marked with IA, IB, IC represents the three phasecurrents. The signal IG represents the measured ground current.

3.4.3.1 Functional diagrams for protection

The following functional diagrams describe the IED’s protection functionality in detailand according to the factory set default connections in the Signal Matrix tool.

Five overcurrent stages are offered for phase overcurrent and short-circuit protection.The inrush detection block’s (INR) output BLK2H provides the possibility to eitherblock the function or multiply the active settings for any of the shown protectionfunction blocks. Three of the overcurrent protections have directional feature and thesedirectional protections can also be used as non-directional protection with settingchanges.

Figure 29: Phase overcurrent protection

The neutral overcurrent protection 51N can be blocked by energizing the binary input 1(X120:1-2). In addition, there are three more directional protection for ground faults.Two negative sequence overcurrent stages (46-1 and 46-2) are included for phaseunbalance protection along with a separate phase discontinuity protection. The phasediscontinuity protection (46PD) provides protection for interruptions in the normal three-phase load supply, like in downed conductor situations. Two separate cold load timersare provided with seconds and minutes ranges to provide utmost flexibility in cold-loadinrush protection. Any functions can be selected to be blocked during the cold loadtimers pickup duration using the Signal Matrix tool.

The thermal overload protection (49F) provides indication of overload situations.

The breaker failure protection (50BF) is initiated via the pickup input by a number ofdifferent protection stages in the IED. The breaker failure protection function offersdifferent operating modes associated with circuit breaker position and the measuredphase and residual currents. The breaker failure protection has two operating outputs:TRRET and TRBU. The TRRET output is used for retripping its own breaker throughthe Master Trip. The TRBU output is used to give a back-up trip to the breakersassociated with the faulty breaker. For this purpose the TRBU trip output signal isconnected to output PO2 (X100: 8-9).

The sensitive earth-fault protection (50SEF) and high impedance fault detection (HIZ)provide protection against high impedance faults. If the load unbalance is high, 50SEFneeds to be set high to avoid misoperations which renders 50SEF ineffective for suchapplications. In those cases, HIZ can provide detection which would otherwise beundetected.

Section 4 Requirements for measurementtransformers

4.1 Current transformers

4.1.1 Current transformer requirements for non-directionalovercurrent protectionFor 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, when theCT 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 IED should be defined in accordance with theCT performance as well as other factors.

Appropriate 'C' class CT should be used based on the total resistances of the CTsecondary circuit. If other accuracy class CTs are used then refer the followingdiscussions.

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 22: 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

1MAC109554 C Section 4Requirements for measurement transformers


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 IED.

The CT accuracy primary limit current describes the highest fault current magnitude atwhich the CT fulfils the specified accuracy. Beyond this level, the secondary current ofthe CT is distorted and it might have severe effects on the performance of theprotection IED.

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 CT burden.

The actual accuracy limit factor is calculated using the formula:

+

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 IED is not exceeded. This isalways 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 theIED. For that reason, in practice, even a few times smaller nominal primary current canbe used than given by the formula.

Section 4 1MAC109554 CRequirements for measurement transformers


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

Current pickup value < 0.7 x (Ikmin / I1n)

I1n is the nominal primary current of the CT.

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

The adequate performance of the CT should be checked when the setting of the highset stage overcurrent protection is defined. The trip 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 pickup current setting is simply according tothe formula.

Delay in operation caused by saturation of current transformersThe saturation of CT may cause a delayed IED operation. To ensure the timeselectivity, the delay must be taken into account when setting the trip times ofsuccessive IEDs.

With definite time mode of operation, the saturation of CT may cause a delay that is aslong as the time the constant of the DC component of the fault current, when thecurrent is only slightly higher than the pickup current. This depends on the accuracylimit factor of the CT, on the remanence flux of the core of the CT, and on the trip 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 the pickupcurrent. Otherwise, the inverse operation time can be further prolonged. Therefore, theaccuracy limit factor Fa should be chosen using the formula:

Fa > 20*Current pickup value / I1n

The Current pickup value is the primary pickup current setting of the IED.

1MAC109554 C Section 4Requirements for measurement transformers


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.

A071142-ANSI V2 EN

Figure 52: 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 to be59.

The pickup current setting for low-set stage (51P) is selected to be about twice thenominal current of the cable. The trip time is selected so that it is selective with thenext IED (not visible in the figure above). The settings for the high-set stage andinstantaneous stage are defined also so that grading is ensured with the downstreamprotection. In addition, the pickup current settings have to be defined so that the IEDoperates with the minimum fault current and it does not trip with the maximum loadcurrent. The settings for all three stages are as in the figure above.

For the application point of view, the suitable setting for instantaneous stage (50P-3) inthis example is 3 500 A (5.83 x I2n). For the CT characteristics point of view, thecriteria given by the current transformer selection formula is fulfilled and also the IEDsetting is considerably below the Fa. In this application, the CT rated burden couldhave been selected much lower than 10 VA for economical reasons.
