基于 Petri网技术 ,利用电力系统实时离散事件 (保护继电器和断路器 )信息 ,探讨了一个具体变电站故障诊断的方法。主要讨论了变电站故障诊断的 Petri网建模 ,计算冗余嵌入 Petri网的错误伴随式矩阵等问题。仿真结果表明该方法计算简单 ,非常适合应用于在线实时监控系统
Based on the Petri net technology, a method of substation fault diagnosis is discussed based on real-time discrete events (protection relays and circuit breakers) information of power system. Petri net modeling of substation fault diagnosis and error adjoint matrix calculation of redundant embedded Petri nets are mainly discussed. Simulation results show that the method is simple and suitable for online real-time monitoring system
