摘要
通过对中性点经消弧线圈接地系统单相接地时零序暂态电流的频域分析和时域分析 ,得出接地导线中零序暂态电流的峰值比健全线路中零序暂态电流的峰值大许多 ,比较峰值的大小可以识别故障线路 ,同时得出零序暂态电流的方向是不确定的 ,不宜采用零序暂态电流的方向作为选线判据。
By analysis of zero sequence transient current when single phase grounding in electric power system whose neutal point connects to the ground via arc suppression coil, that maximum of zero sequence transient current in grounding wire is much greater than in well_condition circuit is concluded. By comparing the size of maximum the malfunction circuit can be found out. At the same time it is concluded that the direction of zero sequence transient current is unknown and should not be used for the basis of line_selection.
