基于模糊综合评判的变压器套管绝缘状态评估
Insulation Condition Assessment of Transformer Bushing Based on Fuzzy Comprehensive Evaluation
摘要
Abstract
To solve the problem that overall assessment of transformer is too general, a fuzzy comprehensive evaluation model is constructed for transformer bushing insulation condition assessment. Due to the fact that constant weight may cause distorted evaluation, the variable weight is introduced to make the evaluation results close to the actual condition of transformer bushing, and the semi-trapezoid distribution function is adopted as a membership function to determine the fuzzy matrix. The ranking eigenvalue is used as a comprehensive rank to determine the condition level of transformer bushing. The case study verifies that the fuzzy comprehensive evaluation is reliable and practical for transformer bushing condition assessment.关键词
