| 摘 要： | 提出一种使故障定位算法能够应用于多电源配电网复故障情况的网络模型，该网络模型考虑了算法中与故障电流有关的量的方向性，在假定由某电源供电的功率流向为正方向之后，多电解配电网的故障定位问题实际上转化为单一电源情况下的故障定位问题，如果对每一个电源都假定一次正方向，在每一个假定正方向下都用故障定位算法求一次故障设备，那么最后就可以找到所有的故障设备。

| Abstract: | A network model is presented in the paper for the application of the fault section location arithmetic to the complex multi source power distribution system. The model takes the directions of variable related to the short circuit current into account. After the positive direction decided by the assumed power flow of some source being considered, the fault section location in the multi source distribution system is translated into the location of the single source system. The fault in all the assumed directions is located. All the faults in the multi source power distribution system can be found out. The simulation results have verified its effectiveness. |
