摘要
对中性点不接地系统单相接地时零序暂态电流和零序全相电流特性进行分析。指出采用零序暂态电流选线时 ,由于存在无暂态过程的情况 ,因此有局限性 ;而采用零序基波电流选线 ,则必须在同一周波内完成采样 ,尽量增加采样点数 。
By analysising the zero sequence transient current and zero sequence total current during single phase grounding fault in power system whose neutral point does not connect to the ground, the limitation of using zero sequence transient current line selection and the question which should be noted when using zero sequence elementary wave current line selection are pointed out.
