| 摘 要： | 在配电网馈线发生单一故障的情况下,其故障区段必位于两个相邻的开关之间,有故障电流和没有故障电流流过的开关其FTU 所采集的信息不相同,从而可以很方便地找到故障区域.但是,由于大部分配电网并没有实施配网自动化,使得配网运行的实时数据难以获得.基于此提出了通过模拟故障、潮流计算,寻找故障区域,并记录下为了隔离故障区域开关动作的个数,作为判断配电网网架结构的一个指标.

| Abstract: | When a single fault occurs on a distribution feeder,the faulty section is probably between two adjacent switches.Since the FTU information on switches with or without faulty current are quite different,the faulty section can be easily found out.However,most distribution network dose not realize automation,which makes it difficult to get the real-time operation data of the distribution network.To solve the above mentioned problem,it is presented that the faulty section can be identified through fault simulation and power flow calculation,and the number of switch actions can be used as an index for evaluating the distribution network. |
