摘要
综合考虑油浸电力变压器的溶解气体分析与电气试验得到的多种故障征兆,在分析大量变压器故障案例的基础上,建立了基于粗糙集的油浸电力变压器故障诊断的具体模型.针对变压器故障的复杂性以及信息的不完备性,对变压器的故障信息和故障类型进行分析总结,利用粗糙集进行约简可以得到诊断结果.实例表明该模型具有计算速度快、正判率高、结果直观等优点.
Synthetically considering various symptoms, gotton from the dissolved gases in oil analysis and some kinds of electrical tests, and the collected fault cases, a diagnosis model is established based on rough set theory. Due to the incompleteness and complexity of fault diagnosis for power transformer, the fault information and type are summarized, and the diagnostic result can be achieved by using the rough set theory. The example results show that this kind of model can get reliable conclusion in the support of incomplete information.
