This paper proposes an approach to fault diagnosis com bining fuzzy sets and fuzzy inference with expert system in the light of large num ber of uncertainties existing in power system fault diagnosis PSFD . Moreover,an attempt applying the distributed problem solving m ethod to PSFD is also made and a distributed PSFD expert system based on fuzzy inference is developed simultaneously. In particular,the practical test in a certain distribution power grid is carried out and the results have shown that the scheme presented in the paper is accurate and practical.
