The design reliability project will compare the reliability and availability for different substation arrangements based on historical switchgear and protection performance. The impact of various fault scenarios will be examined, to identify the appropriateness of substations for extensions or development. This will form a strategy for new connections, extensions or asset replacement decisions. This will also be used to examine alternative substation configurations (double breaker or one and a half breaker systems) and new technologies such as integrated or hybrid switchgear (such as disconnecting circuit breakers or compact units) can be used to make the network more effective.
The purpose of this work is to establish a generic assessment model to compare performance and reliability between different substation configurations under various fault and operational contingencies.
