熵值法赋权的智能变电站二次设备效能模糊综合评价
Comprehensive fuzzy evaluation of effectiveness of secondary equipment in smart substation based on entropy method
摘要
Abstract
Equipment effectiveness evaluation plays an important role in improving the effectiveness of asset management,improving the operation and maintenance mode,and improving the utilization ratio of assets.In this paper,equipment performance parameters were extracted by analyzing every piece comprehensively.Based on historical operation status and equipment performance,parameters of secondary equipment,the performance evaluation index system was established.Comprehensive fuzzy evaluation algorithm was used to evaluate the performance evolution index system.Mountain shaped distribution of membership functions determined membership degrees of the indexes.Entropy method was used to determine index weight,thus effectively avoiding interference of subjective factors.Validity of the model is verified by comparing results of different state indexes of measurement and control devices.关键词
