基于改进熵权法和灰色关联分析的变压器故障诊断
Fault diagnosis of transformer based on improved entropy method and grey correlation analysis
摘要
Abstract
The improved entropy method and the grey correlation analysis method of transformer fault diagnosis is pro-posed to solve the problem of the incomplete data information and low accuracy in fault diagnosis .Firstly, the method standardizes the sample data of transformer fault , then, it uses the improved entropy weight method to determine the index weights of transformer fault diagnosis , and finally , the transformer fault types are determine by calculating the improved grey Euclid weighted correlation degree .The example analysis results show that the validity and feasibility of the proposed method .Comparing with the traditional entropy weight method , the index weight distribution is more rea-sonable , and it can overcome the deficiency of the traditional grey correlation analysis indicators of parity , and the ac-curacy rate of fault diagnosis is significantly higher than the IEC three ratio method and general grey relation analysis .关键词
