运用模糊集理论实现配电网故障定位 ,根据配电网的拓扑结构 ,提出实现网络自动分层的方法 ,再在获得足够故障投诉电话信息的前提下 ,利用模糊集理论实现故障定位。详细介绍了网络的自动分层原理及其算法、故障定位中基于投诉信息的模糊集原理与应用示例。运用 VB5.0及 MSAccess实现了配电网的故障诊断应用程序 ,对实际配电网的大量仿真表明 ,该方法简单、有效 According to the topology of distribution network, a method of realizing automatic network stratification is put forward based on fuzzy set theory. On the premise of getting enough telephone complaints, the fuzzy set theory is used to realize the fault location. This paper introduces the principle of automatic layering of network and its algorithm, the principle and application of fuzzy sets based on complaint information in fault location. Using VB5.0 and MSAccess to realize the fault diagnosis application of distribution network, a large number of simulation of actual distribution network shows that the method is simple and effective
