Insulation Condition Assessment for Power Transformer Bushing Based on Set Pair Analysis and Comprehensive Weights
摘要
Abstract
For the complexity and uncertainty of the assessment indicators in insulation condition assessment of power transformer bushing,the set pair analysis is employed.First,indexes for bushing condition assessment are selected,assessment result is graded,and response strategies are worked out.Then,the weights of the assessment indexes are determined by using the comprehensive weighting method with combination of AHP and entropy method,mathematical expressions are estabhshed to describe the degree of association between evaluation criteria and state level,and a condition assessment model is built using set pair analysis.Example shows that the assessment model based on the set pair analysis and comprehensive weight can effectively reflect the insulation condition of transformer bushing,and the assessment results can be taken as a reference for transformer state-based maintenance.关键词
