基于层次分析的变压器故障诊断决策支持系统

阐述了一套基于层次分析方法的变压器油色谱故障诊断决策支持系统,故障诊断模块使用改良电协研法、灰色关联熵、模糊聚类、人工神经网络等单项分析,弥补了现有诊断方法中的不足.针对每种诊断方法可能出现结论不一致的情况,系统综合分析方法采用层次分析的方法来实现,能对变压器色谱数据进行故障诊断,给出综合分析结论及建议.通过对平顶山电网中的色谱数据进行诊断及其他应用实例,验证了系统的有效性.

A fault diagnosis decision support system based on analytic hierarchy process

A fault diagnosis decision support system for power transformer based on analytic hierarchy process and its modules are introduced.In its modules,the three-ratio-method,grey relational entropy,fuzzy clustering,artificial neural network and analytic hierarchy process are used for integrated analysis,so as to perfect existing diagnosis methods.Possibly has the conclusion inconsistent situation in view of each diagnosis method;for the system synthesis analysis,the analytic hierarchy process is used.The system has realized each module function by layers;and it can diagnose fault in power transformer.The effectiveness of the system is verified by the dissolved gas analysis(DGA) data in Pingdingshan Power Grid and other DGA data.
