【摘要】：针对高压断路器状态评估因素具有模糊性和灰色性的特点,将灰色模糊理论应用到高压断路器的状态评估中。基于试点工程,建立考虑高压断路器运行机理的递阶层次评估模型;采用层次分析法计算各层次评估因素权重集的模部,结合信息充裕程度及专家经验,确定相应评估因素权重集的灰部;综合定性分析与定量分析,以隶属度描述评估因素与状态等级间的模糊关系,并引入点灰度描述模糊关系的不可信程度,建立灰色模糊判别矩阵,进而对高压断路器运行状态进行综合评估。实际算例表明,所提模型能够客观有效地评估高压断路器的状态。
[Abstract]:The grey fuzzy theory is applied to the state evaluation of high voltage circuit breakers in view of the fuzzy and grey characteristics of the state evaluation factors of high voltage circuit breakers. Based on the pilot project, a hierarchical evaluation model considering the operation mechanism of high voltage circuit breakers is established, and the model part of the weight set of each hierarchy assessment factor is calculated by AHP, combining the information adequacy degree and expert experience. Determining the grey part of the weight set of the corresponding evaluation factors, synthesizing qualitative analysis and quantitative analysis, describing the fuzzy relation between the evaluation factor and the state grade by the membership degree, and introducing the point gray level to describe the fuzzy degree of the fuzzy relation. The grey fuzzy discriminant matrix is established and the operation state of high voltage circuit breaker is evaluated synthetically. Practical examples show that the proposed model can objectively and effectively evaluate the state of high voltage circuit breakers.
