基于ID3算法的变压器故障诊断分析

鉴于变压器故障时,故障信息繁杂多样,加之其本身的元器件比较多,运行检修人员往往很难全面把握故障征兆从而确定可能存在故障的变压器元器件。文章应用决策树ID3算法确定浸油式变压器故障部位,该方法基于熵值理论,利用常规电气试验的结论,借鉴现场运行、诊断经验,结合变压器的外部信息,形成变压器故障诊断决策树。

Fault Diagnosis of Transformer Based on ID3 Algorithm

Various complex information and plenty of transformer elements often make an operator or maintenance personnel confused to properly handle premonition of a fault and find the faulted element when a transformer fault occurs.In this paper the decision tree ID3 algorithm is used to confirm fault position of an oil-immersed transformer.This method is used to form a decision tree of fault diagnosis of a transformer based on the entropy theory,by virtue of the practical operation and diagnosis experience,applying conclusions of the routine electric tests and using exterior information.
