Background (Introduction)

• Circuit breaker failure is the condition that happen when the circuit breaker fail to trip or open the circuit during the fault.

• The circuit breaker failure protection scheme is used as a back-up protection that initiate tripping to all adjacent circuit beakers that connected to the feeder of the fault circuit breaker.



• It is an important back-up protection scheme that can minimize the damages of circuit breaker and the system equipments due to the long fault duration that fail to be interrupted.

• It can prevent large cascading tripping which can disturb the healthy circuit or line.



Background (Existing Scheme)

• In the existing system, the breaker failure scheme deployed hardwired connection for transmitting the signal from the relay of the failed breaker bay to the adjacent bay that interconnected with it.

Background



Background (Problem Statement)

• Before any transformation from hardwire communication of breaker failure protection scheme to IEC 61850 GOOSE message, TNB need to analyze and evaluate the performance of this scheme in terms of:– Reliability of the IEC 61850 GOOSE message for breaker

failure protection scheme– Selectivity of the breaker failure tripping with the IEC 61850

GOOSE message– Speed of the IEC 61850 GOOSE message for transmitting the

Project Organization



Problem Statement

• TNB didn’t employ the breaker failure protection scheme in 132kV substation due to– Expensive: current scheme use a dedicated relay.

So only the important substation (500kV, 275kV and 132kV GIS substation) have this function.

– Competency issues: the current breaker failure scheme require a complex scheme and complicated wiring. This required a higher competency level (staff) to perform maintenance and trouble shooting work.
