基于与或树建模的电力系统Petri网故障诊断方法
|
摘要
为进一步提高故障诊断模型的准确性,该文针对传统有色Petri网模型在主保护信号缺失情况下难以进行故障诊断的缺陷,基于与或树方法完善了诊断模型,使其对故障的描述更全面。以保护启动信号、保护出口动作信号和断路器跳闸信号为诊断依据,以主保护、远后备保护和失灵保护为基础实现诊断过程。最后以含分布式电源的典型配电系统为例验证了该模型的有效性和正确性。
In order to improve the accuracy of fault diagnosis model and for the drawback of not diagnosis with no main protection signal in initial colored Petri Net model,this paper improved diagnosis model based and/or tree,making it more comprehensive for fault description.According to protection action signal,protection export action signal and circuit breaker trips signal,based on the main protection,secondary protection and failure protection,the model realized diagnostic process.Finally,utilized typical distribution system with distributed power example verifying the effectiveness and validity of the model.
