| 摘 要： | 在分析故障相和非故障相的暂态电流特征的基础上,提出一种基于暂态电流的故障选相原理。该原理采用小波变换有效地提取了暂态电流特征,从而实现可靠选相。仿真结果表明,该原理不受故障类型、故障时刻、故障过渡电阻、故障位置的影响。

| Abstract: | Through analyzing transient current characters of faulted phase and non-faulted phase at fault instant, the paper presents a principle for faulted phase selection based on transient current, which uses wavelet transform for transient current characters. The simulation results prove that the principle is insensitive to fault type, fault time, transition resistance and fault location. |

| Keywords: | transient current wavelet transform faulted phase selection |
