| 摘 要： | 小电流接地系统单相接地故障时往往伴随着电弧的产生,故障电弧带来了很多高频分量,这也是目前许多选线装置不可靠的重要原因所在。利用故障电弧引起的奇异特征,用小波奇异性检测原理对故障零序电流进行大量的仿真。仿真结果表明,本小波选线算法在发生电弧故障时也能正确选出故障线路,同时也说明了此方法的准确性、可靠性以及高适应性。

| Abstract: | According to the singular character, a lot of simulations are made based on the time and frequency localization character of wavelet transform. The simulation results show that the method of wavelet analysis can select the fault line correctly when the arc-grounding fault occurs, so it has higher reliability, accuracy and adaptability. |
