摘 要:油色谱在线监测是电力变压器在线监测领域常用的方法之一。变压器故障诊断的结果将直接作为变压器是否需要检修的决策依据,鉴于变压器故障原因的复杂性,仅靠单一的故障诊断方法很难满足故障诊断的要求,故将传统故障诊断方法与BP神经网络方法通过Borda模型相结合,以提高变压器故障诊断的准确率,最后用C#语言设计开发了故障诊断系统。该系统改变了以往的定期试验模式,实现了变压器状态在线监测和分析。

Abstract: Oil chromatography monitoring is one of the commonly used methods in the online monitoring field of power transformers. The results of fault diagnosis for a transformer will provide a direct basis for determining whether the transformer needs an overhaul. Due to the complex reasons of transformer faults, it is difficult for a single diagnosis method to meet the requirements of fault diagnosis. In order to improve the accuracy of fault diagnosis, this paper combined the traditional fault diagnosis method with the back propagation (BP) neural network method by the Borda model. The fault diagnosis system developed by C# language improved the traditional mode of routine test and achieved online monitoring and analysis for the state of power transformers.
Key words: transformer online monitoring; fault diagnosis; back propagation neural network; Borda model; C# language
