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.
