试论基于层次分析与熵权法的高压断路器运行状态模糊综合评估

为了使高压断路器运行状态的评估更准确可靠,提高其诊断精确度,提出了运用层次分析法、熵权理论与模糊综合评判相结合的高压断路器运行状态的评估方法。该方法由模糊数学确定各因素的隶属函数,通过层次分析法、熵权理论确定高压断路器运行参数指标的综合权重,结合指标权重与评判矩阵进行模糊运算得到高压断路器的综合运行状态;以SF6高压断路器为例,验证该方法合理有效。

Discussion on the Fuzzy Comprehensive Evaluation on the Operating Conditions of High-voltage Circuit Breaker Based on AHP (Analytic Hierarchy Process) and Entropy Method

In order to make the evaluation on the operating conditions of high-voltage circuit breaker more accurate and more reliable for improving its diagnostic accuracy,this paper advances a new method for evaluating the operating conditions of high-voltage circuit breaker that is combined with AHP,entropy theory and fuzzy comprehensive evaluation,the concrete procedures of which are as following:first,identifying membership function of each factor by fuzzy mathematics;second,determining the comprehensive weights ...
