摘　　要： 结合广西北海市城网自动化发展前景 ,提出了一种可行的基于开关电流越限信号的配电网故障定位遗传算法。算法利用树型数据结构自动识别网络拓扑 ,并采用单一故障完全初始化、最佳保留机制、两断点交叉、可变的交叉及变异概率等机制。仿真测试表明 ,该算法能进行全局寻优求解 ,可自动识别网络拓扑的变化 ,具有很好的容错性能 ,远优于传统的故障电流判别法 。 According to the development of the urban power network automation in Beihai, Guangxi, a feasible inheritance algorithm for fault location in power distribution system is presented based on the signal of over-limit feeder current. The algorithm can identify the network's topology automatically with the tree data structure and some mechanisms such as entire initiation after single fault, the best reservation mechanism, intersection between two breaking points, changeable intersection, variable probability and so on. The simulation test shows that the algorithm can obtain the best overall result and identify the variation of the network topology. The algorithm with the good tolerance and potentiality of on-line application is better than the traditional fault-current identification method.
