摘    要:利用高压输电线路两端故障录波器的不同步数据,提出利用线路两侧工频相量相位差的特点进行测距;该方法不受负荷电流与过渡电阻的影响,不需要进行故障选相和判别真伪根,EMTP仿真结果表明,算法有较高的精度。

关 键 词:输电线路  故障测距  测距  算法

Abstract:The methodology utilizes the properties of phase lap between the two terminal phases to decide the fault location. It is independent of load current, fault type, fault resistance and need not choose the answer from the two soutions. It was tested by the data obtained from EMTP and the results are precise.
Keywords:transmission line  fault location  two-terminal data
