摘要
论述了基于Petri网络理论进行电网故障诊断的方法,描述了故障元件、保护、开关之间内在的动作关系,提出了运用简单的矩阵计算进行诊断的方法,与传统的专家系统相比,大大减少了诊断时间,提高了准确度,适用于各种网络拓扑.网络测试表明:该方法快速、准确,适于在线运行.
This paper describes a new method for power system fault diagnosis using Petri nets theory. Petri nets represents causality between the faults and actions of both protections and circuit breakers. Conventional expert systems applied to fault diagnosis need to manually build complicated knowledge databases and not satisfy real -time demand. The method is very simple and clear. Because it only uses simple matrix calculation for to diagrosis using Petri nets theory, fast and accurate results are obtained. The method is more able than conventional methods to adapt to changing network configurations. Finally this method is tested using a network, it is proved that this method is very fast and accurate and is very suitable for online applications.
