摘要
现有的基于Petri网的配电网故障诊断方法只能找出故障区段、不能辨识出故障类型,针对此问题,提出一种基于Petri网的配电网故障模式辨识方法。同时,对基于Petri网的故障区段定位的电压判据进行了简化,使其只需要利用区段两侧的测量点信息就能进行区段定位。通过配电网的算例,验证了所提方法在故障区段定位和故障模式辨识中的有效性。
Existing fault diagnosis methods based on Petri nets can only find fault section,but can’t identify fault types.To solve this problem,a fault mode identification method based on Petri nets is proposed.At the same time,the voltage criterion of fault section location based on Petri net is simplified,as a result,only the information of measurement points on both sides of the section is needed for the section location.The validity of the proposed method in fault section location and fault mode identification is verified by an example of distribution network.
