Abstract

A new method based on fault-mass made up of a fault source and some non-operations is proposed to diagnose various faults that may occur in substation. The uncertainties in such problems as protective device non-operations, circuit breaker non-operations and missing signals are properly solved. Protection schemes are described as Petri-net models, from which all couples of fault-masses and symptom-masses are obtained. Candidate answers are evaluated by the fitness function, and then the optimal answers are found out. adopting the genetic algorithm. Trials prove that the developed methodology can efficiently identify not only fault-masses but also missing signals according to the known fault symptoms. It has great potential for on-line application.
