摘要(Abstract)：

3/2接线方式可靠性高、检修方便,在500 kV输电系统中获得了广泛的应用。在传统Petri网的基础上,结合故障的层次性与方向性原理、高斯分布系数与500 kV 3/2接线系统保护配置,设计了一种针对3/2接线系统的新型层次性变迁WFPN故障诊断模型。同时考虑到死区故障的存在,防止因死区故障而造成的误判,设计了一种新的拓扑结构。在确定故障元件后,基于模型又设计了一种反向搜索方式,能自动给出元件相关保护与断路器是否故障的简单报告。该故障诊断方法原理简单,可拓展性高,当故障发生时能快速自动得出故障报告,具有比较高的容错性。对调度端的故障判别与自愈性电网发展具有一定帮助。
