摘要
本文提出一种树型电力网单一故障分支的识别方法——零泛器替代法。这种方法的特点是诊断所需要的端口变量易于测量,对于短路和断线故障都适用,测后计算量较少。适用于多分支的树型电力网单一故障分支的识别。经计算机模拟,证明了所提识别方法是有效的。
A new method is presented based on nullor substitution, which is suitablefor detecting single faulty branch with short-circuit or open-circuit on tree type power network. The required current and voltage values of each port are easy to be measured, and the proposed method needs less computations after measurement. It is feasible for single faulty-branch location on tree type powed network with several branches. Simulation by computer shows satisfactory results.
