基于博弈论和改进D-S证据理论的变压器状态模糊综合评判方法
A Fuzzy Comprehensive Judgment Method for Transformer State Based on Game Theory and Improved D-S Evidence Theory
摘要
Abstract
To address the complexities of transformer condition assessment indicators and the overreliance on expert judgment in the evaluation process,a novel method for fuzzy comprehensive assessment of transformer condition was introduced,which is based on gaming theory and an improved version of the D-S evidence theory.First,the analytic hierarchy process(AHP)and the Critic method was adopted to determine both the subjective and objective weights of the evaluation indicators.These weights are then combined using game theory,reducing the dependence on expert opinions in traditional weight determination methods.Second,instead of traditional membership functions,cloud models was employed to preserve the inherent uncertainty in fuzzy assessments.Finally,membership information at the project level was fused by using improved D-S evidence,eliminating paradoxical results that can occur when combining high-conflict evidence.Through the results of case studies,the method effectively assesses the transition probabilities of various transformer states.关键词
