Research on Evaluation Method of AC Filter Circuit Breaker Based on Fuzzy Hierarchy Method

In order to improve the safe and stable operation ability of AC filter circuit breakers, an evaluation method for AC filter four-break circuit breakers based on fuzzy hierarchy method is proposed. Firstly, based on the analytic hierarchy method and gray theory, an index evaluation system based on breaking wear, time parameters and other factors is proposed. Secondly, a comprehensive evaluation model is established, and the comprehensive weights of each index are obtained by using the combined weighting method, which effectively avoids the problem that the single weight method is not objective and accurate. Then, the fuzzy evaluation algorithm is introduced into the comprehensive evaluation model of AC filter circuit breaker, and the comprehensive evaluation is realized. Finally, the evaluation results are compared with the maintenance results, which verifies the effectiveness of the evaluation method proposed in this paper.
