摘　　要：为解决分接开关故障诊断以主观经验、缺乏系统化流程以及诊断结果与分接开关实际发生故障存在偏差等问题,依据当前分接开关主要故障分类,提出基于模糊Petri网的有载分接开关故障诊断模型,并结合分接开关典型故障案例,验证模型有效性。研究结果表明:基于模糊Petri网的分接开关故障诊断模型能够有效处理故障概率中不确定性因素,具有容错性好、运行效率高等优势,研究结果可为提高分接开关故障诊断的准确性、保障电力系统安全稳定运行提供参考。Aiming at the problems that the fault diagnosis of tap changer depends on the subjective experience and lacks the systematic process,and there is the deviation between diagnosis results and actual fault of tap changer,according to the current classification on main faults of the tap changer,a fault diagnosis model of on-load tap changer(OLTC)based on fuzzy Petri net was proposed,and the validity of the model was verified by combining with the typical fault cases of tap changer.The results showed that the fault diagnosis model of tap changer based on fuzzy Petri net could effectively deal with the uncertain factors in the fault probability,and had the advantages of good fault tolerance and high operating efficiency.The research results can provide reference for further improving the accuracy and efficiency of OLTC fault diagnosis in our country.
