基于萤火虫算法的断路器可靠性分析与研究

Research of Reliability Analysis of Circuit Breaker Based on Firefly Algorithm

对断路器故障进行统计分析,建立断路器故障树,然后通过模糊层次分析法对故障树逐层定量分析,求解出各故障因素权重,同时为了提高求解精度,采用萤火虫算法对权重进行寻优。最后结合断路器实际运行情况,建立断路器可靠性评估模型,进行可靠性评估。

At first, it made a statistical analysis of circuit breaker failure to build the failure tree analysis. Then it made a analysis for the failure tree analysis with the fuzzy analytic hierarchy in order to solve the fault factor weight. And the firefly algorithm could be made for optimal to improve the factor weight precision. Finally according to the real operation of circuit breaker, it made a reliability assessment with breaker reliability evaluation model.
