摘要
在分析灰色关联度应用于故障诊断的基础上,提出了电力变压器故障的灰色关联度诊断法,从变压器的油中气体中提取特征参数,讨论了特征参数的无量纲化处理方法。通过仿真实验表明该方法具有良好的诊断果果。
On analyzing the features of applying gray relations to fault diagnosis,a diagnostic method of gray relation for electric transformer fault diagnosis is presented in this paper.Some characteristic parameters are abstracted from gas of transformer oil and the dimensionless processing of the parameters is also discussed.Experiment on transformer confirms a good result of this diagnostic method.
