EMTDC/PSCAD software simulations show that the novel algorithm is independent of fault inception angle, insensitive with the source-line impedance ratios and able to measure the fault impedance at the condition of different load current and diverse fault resistance.
EMTDC/PSCAD仿真表明,新算法与故障起始角度无关,对电源线路阻抗比值不敏感,能准确地测量不同负荷电流和不同过渡电阻情况下单相接地的故障阻抗。

The analysis shows that the measured impedance at the head of the line is not proportional to the fault distance when a three-phase fault occurs at the end of the line.
分析表明，线路末端三相故障时，线路首端的测量阻抗不与故障距离成正比。
Because the impedance fault location method is easily influenced by the factor such as fault resistance, transformer error and asymmetrical line configuration, the fault location accuracy is lower.
由于阻抗法易受过渡电阻、互感器误差、线路结构不对称等因素的影响，所以测距精度不高。
Especially it solves the identification problem of high impedance fault well.
