摘要
基于模式分析和分布参数电路理论，借助多频激励诊断方法，提出树型配电线路两相短路、单相接地和两相接地的模分量解耦分析法故障测距，利用树网单端信息完成故障分支识别、故障定位和过渡电阻定值。大量故障测距的计算机模拟和于故障模型仿真线上的故障测距试验表明，该方法有效。
On the basis of model analysis, distributed parameter circuit theory and multifrequency excited diagNosis metXod, a new algorithm of line-to-line, line-to-ground and 2-line-to-ground fault location for tree-type distribution system is proposed in order to complete (1) fault branch iddntification; (2) fault location; (3) fault value, so what is called separated mode component algorithm. A lot of the simulation of fault diagnosis by computer and tests on the fault model simulation lines demonstrate that the algorithm is effective.
