提出了基于零模检测波速度与故障距离关系曲线的配电网故障测距迭代算法。针对零模检测波速度随故障距离变化较大的问题，通过分析及仿真发现了零模检测波速度随故障距离的变化规律，利用该规律给出了零模检测波速度的距离表达式。将此表达式结合基于零模行波分量和线模行波分量速度差的测距公式，给出了故障测距的迭代算法，避免了零模波速度难以确定的问题。通过 ATP 及 Matlab对该算法进行仿真，仿真结果证实了该方法的有效性和可靠性。

An iterative algorithm using the relation curve between the detected zero-mode wave velocity and fault distance in distribution network for fault location is presented. About the speed instability of detected zero-mode wave, this paper finds the variation between detected zero-mode wave velocity with the fault distance by analysis and simulation, and gives the distance expression of detected zero-mode wave velocity by using the variation. By combining the expression and fault location formula based on the difference of wave velocity between zero mode component and aerial mode component of traveling wave, it gives the iteration algorithm for fault location. The iterative algorithm avoids the problem of determining the zero-mode wave velocity. The efficiency and reliability of the algorithm are verified by ATP and Matlab.
