6. Control

Te relay ofers status and control o one or two breakers, depending on the standard conguration selected, with a set o push-buttons on the ront panel local human machine interace (LHMI) or

opening and closing a breaker. Flexible remote breaker control o select-beore-trip (SBO) or direct trip is also available with each o the supported DNP3.0 Level 2+, Modbus and IEC 61850 communication protocols. Interlocking schemes required by the

application are congured with the signal matrix tool in PCM600 by the application are congured with the Signal Matrix ool (SM) o the REF615 user tool PCM600.

7. Measurements

Te relay continuously measures the phase currents, the sequence components o the currents and the residual current. I the relay includes the ground ct option, it also measures the ground current, IG. In addition, the relay calculates the demand and minimum and maximum demand currents over a user-selectable pre-set time rame, the thermal overload o the protected object, and the phase unbalance value as a ratio between the negative sequence and positive sequence currents. With V inputs options, voltage, power and energy (single-phase and three-phase

quantities), power actor and requency measurements and minimum and maximum demand watts and vars are available.

Te values measured can be accessed locally via the user interace on the relay ront panel or remotely via the communication interace o the relay. Te values can also be accessed locally or remotely using the web-browser based user interace.

8. Digital fault recorder

Te relay is provided with a digital ault recorder (DFR) eaturing up to our analog and 64 binary signal channels. Te analog channels record either the waveorm or the trend o the currents measured.

Te analog channels can be set to trigger the recording unction when the measured value alls below or exceeds the set values. Te binary signal channels can be set to start a recording on the rising or the alling edge o the binary signal or both.

By deault, the binary channels are set to record external or internal relay signals, e.g. the pickup or trip signals o the relay stages, or external blocking or control signals. Binary relay signals such as a protection pickup or trip signal, or an external relay control signal over a binary input can be set to trigger the recording. With the V  option, phase and ground voltage waveorms would be available or inclusion in each digital recording.

9. Events recorder

Te IED includes a sequence o events recorder (SER) that logs important event activity. Te relay has the capacity to store in non-volatile memory the most recent 1024 events in a rst-in-rst-out (FIFO) bufer with each event date and time stamped to 1 ms resolution. Te event log acilitates detailed pre- and post-ault analyses o eeder aults and disturbances.

Te SER inormation can be accessed locally via the user interace on the relay ront panel or remotely via the communication interace o the relay. Te inormation can urther be accessed, either locally or remotely, using the web-browser based user interace.

(18)

10. Recorded data

Te relay has the capacity to store in non-volatile memory the most recent 128 ault records or user post-ault analysis. Each record includes the current values, the Pickup times o the protection blocks, time

stamp, etc. Te ault recording can be triggered by the pickup signal or the trip signal o a protection block,

or by both. Te available measurement modes include DF, RMS and peak-to-peak. All 128 ault records are retrievable and viewable via all protocols, the local HMI, web-based HMI and user tool PCM600.

Demand and minimum and maximum demand currents, watts and vars with date and time stamp are stored as separate recorded data. Te power demand values include single-phase and three-phase quantities with wye- connected Vs and three-phase quantities with delta-connected Vs.

Additionally, or congurations A, C and D, a Load Prole eature is included standard. Tis eature records demand currents, watts and vars and bus voltage quantities, depending on the specic conguration, that present a clear view o bus stability and eeder loading. Such load prole is quite useul or system planners. Te Load Prole data recording rate is set by the demand time interval setting and stored in non-volatile memory. For a demand time interval o 15 minutes, approximately 40 days o data is recordable in a rst-in rst-out (FIFO) bufer. Te prole data is retrievable via the relay user tool PCM600 and viewable through its COMRADE viewing tool Wavewin.

11. Circuit-breaker

condition monitoring

For continuous knowledge o the operational

availability o the REF615 eatures, a comprehensive set o monitoring unctions to supervise the relay health, the trip circuit and the circuit breaker health is included. Te breaker monitoring can include checking the wear and tear o the circuit breaker, the spring charging time o the breaker operating mechanism and the gas pressure o the breaker chambers. Te relay also monitors the breaker travel time and the number o circuit breaker (CB) operations to provide basic inormation or scheduling CB maintenance. For standard congurations “B” and “E”, there is a condition monitoring eature or each o the two breakers supported.

12. Trip-circuit

monitoring

Te trip-circuit monitoring continuously supervises the availability and operability o the trip circuit. It provides open-circuit monitoring both when the circuit breaker is in its closed and in its open position. It also detects loss o circuit-breaker control voltage. Local and remote indication are programmable to ensure immediate notication so the necessary steps can be established to correct beore the next ault event occurs.

13. Self-diagnostics

Te relay’s built-in sel-diagnostics system

continuously monitors the state o the relay hardware and the operation o the relay soware. Any ault or malunction detected will be used or alerting the operator. A permanent relay ault will block the protection unctions o the relay to prevent incorrect

(19)

17. Power quality

Te ability to monitor and detect current and voltage harmonics and short duration system disturbances with the REF615 is possible through the optional power quality (P) unction. Tis unction enables

studying system quality conditions, documenting cases and implementing new procedures to improve reliability o service. Te P unctions include these eatures per the IEEE 1159 standard:

• Current total demand distortion (DD) • Voltage total harmonic distortion (HD) • Sags(Dips), Swells and Interrupts

18. Single-line diagram

(SLD)

Te relay includes the ability or the user to design a unique single line diagram (SLD) view in the ront panel LHMI LCD. An applicable deault SLD view

is provided or each standard conguration. Te SLD exible programming allows or showing a one-line drawing o the relay application, metering values and text strings speciying, e.g., specic eeder and breaker inormation. Tis reduces signicantly time the substation personnel need to obtain this relevant inormation rom smaller LCDs.

14. Fuse failure

protection

Depending on the chosen standard conguration, the IED includes use ailure supervision unctionality. Te use ailure supervision detects ailures between the voltage measurement circuit and the IED. Te ailures are detected by the negative sequence based algorithm or by the delta voltage and delta current algorithm. Upon the detection o a ailure the use ailure supervision unction activates an alarm and blocks voltage-dependent protection unctions rom unintended operation.

15. Current circuit

supervision

Depending on the chosen standard conguration, the IED includes current circuit supervision. Current circuit supervision is used or detecting an open in the current transormer secondary circuits. On detecting an opening circuit, the current circuit supervision unction activates an alarm LED and blocks certain protection unctions to avoid unintended operation.

Te current circuit supervision unction calculates the sum o the phase currents rom the protection cores and compares the sum with the measured single reerence current rom a core balance current transormer or rom separate cores in the phase current transormers.

16. Load pro

ﬁ

recording

Te relay includes a load prole recording eature in all standard congurations. Te load prole records, at least, stored demand current values and, with the V inputs option, demand watts and vars values at a rate

(20)

20. Access control

o protect the IED rom unauthorized access and to maintain inormation integrity, the IED is provided with a our-level, role-based authentication system with

administrator programmable individual passwords or the viewer, operator, engineer and administrator level. Te access control applies to the rontpanel user interace, the web-browser based user interace and the PCM600 tool.

21. Inputs and outputs

Te availability o current (ct) and voltage (vt) analog inputs depends upon the standard conguration ordered. Standard and optional binary inputs and outputs (I/O) also depend upon the selected IED conguration. able 4 details the analog inputs and I/O available or each conguration and analog inputs order code characters.

Te phase-current inputs are user programmable or 5 A or 1 A ct secondary nominal rating. Te ground ct option is programmable or 5/1 A nominal rating, the SEF/HIZ ct option has a xed 0.2 A nominal rating. Te sensitive earth ault ct option provides SEF protection and includes a separate, independent HIZ protective unction or detecting downed conductors.

Te phase-current and ground current nominal rating o 5 A or 1 A are selected in the relay soware. Te nominal secondary voltage o the three-phase and ground V inputs are user programmable.

Te binary input turn-on thresholds are programmable rom 18…176 V DC by adjusting the relay’s parameter settings.

All binary input and output contacts are reely

programmable with the signal matrix tool in PCM600 soware user tool.

Relay analog input and binary input/output overview: • Tree phase-current inputs

• Optional ground current or SEF/HIZ ct current input • Optional three-phase, synch check and ground V inputs

• wo NO outputs with trip circuit monitoring • One Form C output

• One Form C sel-check alarm output • Additional binary inputs and outputs optional • High-speed outputs (1 ms operate time) optional

19. Cable fault detection

(CFD)

Te REF615 ofers an option eeder cable ault detection (CFD) unction that is able to real-time detect extremely short duration overhead and

underground aults in eeders. Tis dedicated unction is programmable to monitor and detect sel-clearing and use-cleared aults. Tese short duration aults are typically undetectable by conventional protection where there is no operation o their substation

breaker or eeder recloser. Where dispatchers gain knowledge o these events rom customer calls, this real-time detection provides immediate indication to the dispatcher prior to the rst customer call. Overall outage restoration times may be reduced having knowledge o such eeder event as soon as they happen improving a utility’s reliability metrics.

22. Communications

Te relay (IED) supports a range o communication proto-cols including IEC 61850, Modbus® and DNP3.0 Level 2. Operational inormation and controls are available through these protocols. Certain communication unctionality, e.g., horizontal communication between relays, is only enabled by the IEC 61850 communication protocol.

Te IEC 61850 communication implementation supports all monitoring and control unctions. Additionally, parameter settings, disturbance recordings and ault records

can be accessed using the IEC 61850 protocol. Disturbance recordings are available to any Ethernet-based application in the standard COMRADE le ormat. Te IED supports simultaneous event reporting to ve diferent clients

on the communication network bus.

Te IED can send binary signals to other IEDs (so cal led horizontal communication) using the IEC 61850-8-1 GOOSE (Generic Object Oriented Substation Event) prole. Binary GOOSE messaging can, e.g., be employed

or protection and interlocking-based protection schemes. Te relay meets the GOOSE perormance requirements or tripping applications in distribution substations, as dened by the IEC 61850 standard. Also, the IED supports the sending and receiving o analog values using GOOSE messaging. Analog GOOSE messaging enables ast transer o analog measurement values over the network bus, thus acilitating, or example, sharing o RD input values, such as surrounding temperature values, to other IED applica-tions.

Te IED ofers an optional second Ethernet bus to enable the creation o a sel-healing Ethernet ring topology. Te IED communication module options include both galvanic and ber-optic Ethernet combinations. Te communica-tion module including one ber-optic LC port and two galvanic RJ-45 ports is used when the ring between the IEDs is built using CA5 SP cables. Te LC port can in this case be used or connecting the IED to communication ports outside the switchgear. Te communication module

including three RJ-45 ports is used when the whole substa-tion network bus is based on CA5 SP cabling.

Te sel-healing Ethernet ring solution enables a cost-efec-tive communication ring solution controlled by a managed switch with rapid spanning tree protocol (RSP) support to be created. Te managed switch controls the consistency o the loop, routes the data and corrects the data ow in case o a communication disturbance. Te IEDs in the ring topology act as unmanaged switches orwarding

unrelated data tra c. Te Ethernet ring solution supports the connection o up to 30 ABB 615 series relays. I more than 30 IEDs are to be connected, it is recommended that the network is split into several rings with no more than 30 IEDs per ring. Te sel-healing Ethernet ring solution avoids single point o ailure concerns and improves the reliability o the communication. Te solution can be applied or the Ethernet-based IEC 61850, Modbus and DNP3.0 Level 2 protocols.

All communication connectors, except or the ront port connector, are placed on integrated optional communica-tion modules. Te IED can be connected to Ethernet-based communication systems via the RJ-45 connector (100Base-X) or the ber-optic LC connector (100Base-FX). I connection to a serial bus is required, the 10-pin RS-485 screw-terminal or the ber-optic S connector can be used. Modbus implementation supports RU, ASCII and CP modes. Besides standard Modbus unctionality, the IED supports retrieval o time-stamped events, changing the ac-tive setting group and uploading o the latest ault records. I a Modbus CP connection is used, ve clients can be connected to the IED simultaneously. Further, Modbus serial and Modbus CP can be used in parallel, and i required both IEC 61850 and Modbus protocols can b e run simultaneously.

DNP3.0 Level 2 supports both serial and CP modes or connection to one master. Additionally, changing o the active setting group is supported.

When the IED uses the RS-485 bus or the serial com-munication, both two- and our wire connections are supported. ermination and pull-up/down resistors can be congured with jumpers on the communication card so external resistors are not needed.

Te IED supports the ollowing time synchronization methods with a time-stamping resolution o 1 ms: Ethernet-based:

• SNP (Simple Network ime Protocol) – primary and secondary SNP servers supported

With special time synchronization wiring: • IRIG-B (Inter-Range Instrumentation Group - ime Code Format B)

In addition, the IED supports time synchronization via the ollowing serial communication protocols:

• Modbus
