Standardized communication

REF615 supports the new IEC 61850 standard for in

ter-device communication in substations. The relay

also supports the industry standard DNP3.0 and Mod

bus® protocols. The implementation of the IEC 61850

substation communication standard in REF615 en

compasses both vertical and horizontal communica

tion, including GOOSE messaging and parameter set

ting according to IEC 61850-8-1. The substation

configuration language enables the use of engi

neering tools for automated configuration, com

missioning, and maintenance of substation devices.

Pre-emptive condition monitoring

For continuous knowledge of the operational avail

ability of the REF615 features, a comprehensive set

of monitoring functions to supervise the relay

health, the trip circuit, and the circuit breaker

health is included. The breaker monitoring can in

clude checking the wear and tear of the circuit

breaker, the spring charging time of the breaker

operating mechanism and the gas pressure of the

breaker chambers. The relay also monitors the

breaker travel time and the number of circuit

breaker operations to provide basic information

for scheduling breaker maintenance.

Bus protection via GOOSE

The IEC 61850 implementation in REF615 also in

cludes fast peer-to-peer communication, over the

substation bus. Use GOOSE communication be

tween REF615 IEDs of the incoming and outgoing

feeders of a substation cooperate to form a stable,

reliable, and high-speed busbar protection system.

The cost-effective GOOSE-based busbar protec

tion is obtained by configuring the IEDs and the

operational availability of the protection is assured

by continuous supervision of the protection IEDs

and their GOOSE messaging over the station bus.

No separate hard-wiring is needed for the horizon

tal communication between the switchgear cubicles.

The REF615 is a dedicated feeder protection and control relay perfectly

aligned for the protection, control,measurement and supervision of

utility substations and industrialpower systems.

REF615 is a member of ABB’s Relion® family and a part

of its 615 protection and control product series. The

615 series protection and control relays are character

ized by their compactness and withdrawable design.

Engineered from the ground up, the 615 series has

been designed to unleash the full potential of the IEC

61850 standard for communication and interoperabil

ity of substation automation devices.

Application

The REF615 provides main protection for overhead

lines, cable feeders, and busbar systems of distribu

tion substations. It can be applied for protection and

control of grounded and ungrounded distribution sys

tems. Flexible order coding allows for choosing cur

rent-only or current-and-voltage configurations to

best fit your distribution feeder application needs.

Protection and control

The REF615 is the most powerful, advanced and sim

plest feeder protection relay in its class, perfectly of

fering time and instantaneous overcurrent, negative

sequence overcurrent, phase discontinuity, breaker

failure, thermal overload, and voltage metering and

protection. The relay also features optional high im

pedance fault (HIZ) protection for grounded and un

grounded distribution systems. Also, the relay incor

porates a flexible three-phase multi-shot auto-reclose

function for automatic feeder restoration in tempo

rary faults on overhead lines.

Enhanced with safety options, the relay offers a

three-channel arc-fault detection system for supervi

sion of the switchgear.

The REF615 also integrates basic control functionality,

which facilitates the control of one circuit breaker via

the relay’s front panel human machine interface (HMI)

or remote control system. To protect the relay from

unauthorized access and to maintain the integrity of

information, the relay has been provided with a four

level, role-based user authentication system, with in

dividual passwords for the viewer, operator, engineer,

and administrator levels. The access control system

applies to the front panel HMI, embedded web

browser based HMI, and the PCM600 relay setting and

configuration tool.

Bus protection via GOOSE

The IEC 61850 implementation in REF615R includes

fast peer-to-peer communication, over the substation bus.

Use GOOSE communication between REF615R IEDs of the

incoming and outgoing feeders of a substation to form a stable,

reliable, and high-speed busbar protection system. The cost-ef

fective GOOSE-based busbar protection is obtained by config

uring the IEDs and the operational availability of the protection

is assured by continuous supervision of the protection IEDs

and their GOOSE messaging over the station bus. No separate

hard-wiring is needed for the horizontal communication between

the switchgear cubicles.

S800 I/O is a comprehensive, distributed and modular process I/O system

that communicates with parent controllers over industry-standard field buses.

Thanks to its broad connectivity it fits a wide range

of process controllers from ABB and other vendors.

By permitting installation in the field, close to sensors and

actuators, S800 I/O reduces the installation cost by reducing

the cost of cabling. And thanks to features such as “hot swap”

of modules, “on-line” reconfiguration and redundancy options,

it contributes to keeping production – and thereby profits – up.
