| 摘要: |
| 提出了一种反映馈线区域和开关设备拓扑联接关系的网络关联描述矩阵模型，并给出了基于这一模型的馈线故障区域定位的新方法，可直观地定位出故障区域，且同时能确定出隔离该区域所应断开的电源侧开关，对分支末梢区域故障也同样适用。该算法程序设计简单，进一步满足了故障定位的实时性要求，并可推广至多电源复故障系统。通过算例证明了此算法的正确性。 |

| Abstract: |
| A network describing incident matrix that depicts topology connection between distribution feeder sections and switches is introduced. Based on the model an algorithm is presented to locate faulty sections in distribution feeder network. It locates faulty sections directly and decides simultaneously which switches on the power source side should be cut off to isolate them. It also works for faults at branch ends of distribution network. Its program design is simple and further meets the need of real-time fault locating. It can be applied to system with multi-power sources and complex faults, which is proved correct by examples. |
