Abstract: This paper proposes a method of fault diagnosis of power systems based on a knowledge‐based approach. It makes use of information on relays and circuit breakers. The feature of this method is that the relay sequence is represented by a logical circuit. In this circuit the following two relations are represented; a logical relation between inputs and output of a gate and a connective relation between logical gates. These two relations are expressed by production rules in the knowledge base. When the information from relays and circuit breakers is given to the logical circuit, faulty components are pointed out.
