摘要
目前馈线故障定位算法不能满足配电网运行方式多样化和馈线保护快速性的要求,文章提出了能自动适应实时运行方式的配电网馈线描述方法,首先形成对整个网络结构的连通性描述,然后对网络描述进行分解,形成多条馈线的描述;并在此基础上提出了故障区段定位的快速算法。该算法也适用于多电源供电、多线路同时故障等复杂配电网情况。为实现馈线全线速动保护提供了理论基础。
At present the fault location algorithm for feeder cannot self-adapt to operation mode of distribution network and meet the request of quickness of relaying.A method to describe feeder in distribution network,which can self-adapt to real-time operation mode,is presented,at first the connectivity description for the whole network structure is formed,then the network description is decomposed into feeder description.Based on this description,an algorithm,which can locate the fault section of a feeder without ...
