Abstract

In order to assess the reliability of circuit breaker more scientificly and effectively, a method based on improved fuzzy analytic hierarchy process and genetic algorithm is presented in this paper. Firstly circuit breaker fault tree is established according to analyzing the circuit breaker failures and which make the complex circuit breaker system failures into all kinds of basic types of failures; Secondly, Improved Fuzzy Analytic Hierarchy Process(IFAHP) is designed to analyze the fault tree, it uses the relationship between the layers of fault tree to establish fuzzy judgment matrix and convert the fuzzy consistent qualification to constrained optimization problems; Then Genetic Algorithm(GA) is adopted to get the weight of each fault which can find the optimal solution quickly and accurately; Finally, according to the practical operation of circuit breaker, high voltage circuit breaker reliability evaluation model is established to assess the reliability of circuit breaker. The analytical result of practical sample verifies the accuracy of the proposed method.
