T接输电线路故障测距的算法

Research on Fault Location Algorithm of T-connection Transmission Line

针对当前多分支输电线路故障测距的不足,结合无分支输电线路的故障测距算法,提出T接输电线路的故障分支识别,并采用集中参数线路模型和分布参数线路模型求解故障距离。

Aimed at the deficiency of multi-terminal transmission line fault location at present, combining with the fault location algorithm of transmission line which does not have branch, the author proposed the fault circuit identification method of T-connection transmission line, and solved the fault location with the lumped parameter circuit model and the distributed parameter circuit model.
