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.

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.
