| 摘 要： | 针对中性点不接地和经消弧线圈接地小电流系统选线不准确的问题,从零序暂态电流特性入手分析了零序暂态电流呈容性的特征频带SFB,提出利用小波变换提取SFB频段内暂态零序电流电压,实现小电流接地系统单相接地故障线路判别。

| Abstract: | In view of the circuit selection error in the little current grounding power system with neutral not grounding or neutral grounding via peterson coil,and based on the characteristic of zero phase transient current,the special frequency band(SFB) of which zero sequence transient current is of capacitance was analyzed,and presented a method by picking up transient zero phase current and voltage of SFB with wavelet to identify the single phase grounding fault circuit in little current grounding system. |

| Keywords: | wavelet-transform capacitance single phase grounding fault |
