集成诊断方法在变压器故障诊断中的应用

Application of Integrated Diagnosis Method to Transformer Fault Diagnosis

为了提高传统油中溶解气体分析的诊断能力,克服单一诊断方法的不足,充分利用各种诊断方法的优势,提出一种变压器智能集成故障诊断方法,建立了基于三比值法、模糊理论和线性分类器的集成诊断模型。诊断结果表明,采用集成诊断方法能有效弥补单一诊断方法的不足,提高故障诊断率。

To enhance ability of conventional dissolved gas analysis（DGA） and overcome disadvantages of single diagnosis method and take advantages of vary diagnosis method,an intelligent integrated fault diagnosis method is provided and a novel integrated diagnosis model is established based on three-ratio method,fuzzy theory and linear classifier.Experimental results are presented to verify effectiveness of method and improve fault diagnosis rate.
