Research on the Weight of Transformer Evaluation Index Based on Fuzzy Analytic Hierarchy Process
The reliability analysis of the transformer affects the safety and economic benefits of the power system. This paper first divided the transformer operation status levels into:good,normal,attention,abnormal and serious. Then,according to the on-line monitoring data of transformer,the evaluation index system of transformer running state was constructed,and the weight matrix of evaluation index was analyzed based on fuzzy hierarchy method. The weight matrix comprehensively considers the expert opinions and the actual operation parameters of the transformer,which is closer to the actual state of the transformer,providing technical support for monitoring the operation state of the transformer.
