Condition Assessment Method for Transmission Line with Multiple Outputs Based on Variable Weight Principle and Fuzzy Comprehensive Evaluation
摘要
Abstract
In order to improve the accuracy of transmission line condition assessment,a condition assessment method of transmission line with multiple outputs based on variable weight principle and fuzzy comprehensive evaluation was proposed.The key evaluation factors of the transmission line state were selected,and model with multiple outputs classified as tower section units,tower sections,line units and whole operation state of the line was obtained.Based on variable weight principle,a balanced function was introduced to adjust the weight coefficient of various evaluation factors determined by analytic hierarchy process.The results show that the improved membership function can be applied to express the distribution of evaluation factors more accurately and the balanced function improves the situation that the serious deviation of evaluation index from the normal value under constant weight coefficient does not affect the result.The practical engineering calculation and comparative analysis with other methods show that the condition assessment method of transmission line established in this paper has good practical prospective.关键词
