摘要
首先分析了灰色关联分析方法的基本理论,在此基础上提出把灰色关联理论用于变压器的故障诊断,分析了大量故障变压器的油中溶解气体(DGA)数据,并以DGA数据为基础建立了变压器故障诊断灰关联模型,事实证明该方法能很好地诊断并预测变压器的故障类型。
Analyzed the basic theory of gray relational diagnosis methods. Given the method which using the gray relational theory on transformer fault diagnosis . Analyzed the DGA data of many transformer's faults and founded the gray relational transformer fault diagnosis model based on the data of DGA. It is proved by the fact that this method can correctly diagnose and predict the transformer's fault.
