Abstract :
An algorithm is presented to evaluate substations reliability, which takes into account breaker failures, blocked breaker and breaker backup protection to isolate failures in a substation. Passive and active outages and two evaluation criteria are considered. This is, substation fails if one point of load fails or substation fails if all points of load fail. The cost of the energy not supplied is used to evaluate and economically compare the substations reliability.
