摘要
分支线路单端测试故障定位方法要求故障测试数据准确，实际系统发生故障时数据测试偏差不仅对故障定位产生偏差，而且也将对分支线路真伪故障的识别产生影响。通过理论分析提出：起端相位测试偏差是故障定位准确性和真伪故障识别的关键。
The radial transmission line fault location method through one terminal measurement demands the fault measurement data and the line parameters are accurate. The measurement data errors in practical systems affect not only the accuracy of locating fault, but also distinguish between real and false fault in the radial transmission line. After theory analysis, this paper proposes an ideal that the phase measurement error at the initial terminal is the essential to the accuracy of the fault location and distinguish between the real and false fault.
