| 摘 要： | 在小电流系统中，利用稳态零序电流分析单相接地故障时的选线精度不够理想。针对这一问题，采用负序分量，结合小波变换技术建立了基于暂态电气量的选线方法，选线过程采用相对值建立判据。研究表明，此方法受中性点接地方式影响较小，具有较好的选线精度。

| Abstract: | In small current grounding system, the method using steady zero sequence currents is not satisfied in selecting single phase to ground faults. In this paper, techniques of wavelets and transient component are used to form the method for fault line selection, the process uses relative quantity to build judgment. Research shows that the grounding mode of neutral point has little effect on this method and it has high selecting accuracy. |
