摘要

消弧线圈接地配电网发生高阻接地故障的概率较大，现有的故障检测和区段定位方法存在准确度低，实现难度大等问题。文中分析了消弧线圈接地配电网发生高阻接地故障时的并联谐振过程，研究了零序暂态衰减周期分量在故障点上下游的分布特征，得出了故障点上游和下游的零序电流衰减周期分量在相位上存在较大差别的结论。提出了一种基于零序电流衰减周期分量的高阻接地故障区段定位方法。该方法由配电自动化主站收集线路中各故障区段定位终端计算的零序电流衰减周期分量相位，并利用该相位和估算的过渡电阻判断故障区段。基于实时数字仿真系统（RTDS）对所提区段定位方法进行了仿真验证，结果表明该方案具有较好的准确性和可行性。

Abstract

High impedance grounding faults occur frequently in distribution network with arc suppression coil grounding. There are some problems in existing fault detection and location methods

such as low accuracy and difficulty in implementation. Parallel resonance process is analyzed when high impedance grounding fault occurs in distribution network with arc suppression coil grounding， and the distribution characteristics and the phase differences of the declining periodic component of zero sequence current at the upstream and downstream of the fault points are also investigated. A fault section location method for a high impedance grounding fault based on the declining periodic component of zero sequence current is proposed in this paper. The main station in distribution automation collects the phases of declining periodic component of zero sequence current calculated by the fault location units of each fault section in the feeder

then the phases and estimated transition resistance are used to select the fault section. The proposed fault location method is verified by RTDS simulation

and the results show that the proposed method is accurate and feasible.
