• Results indicate that the method effectively raises the accuracy of faulty line detection for power system with small grounding current.

  结果表明，该方法有效地提高了小电流接地选线的準确性。

• The EMTDC simulations indicate that the method can find out the faulty line correctly and prove that the analysis of the angle-frequency characteristic of zero impedance of the line is correct.

  EMTDC仿真试验结果表明该方法可以準确地实现单相故障选线，并验证了文章对输电线路零序输入阻抗相频特性分析的正确性。

• The average correlation coefficient is calculated to remove the errors caused by asynchronous sampling and the faulty line selection list is sorted according to the fault probability of line.

  通过求取相关系数平均值，避免数据采集不同步引起的计算误差，得到按照发生线路故障可能性大小排列的故障选线序列。

• The other is to inject current. It selects the faulty line and realizes zero residual current based on concept of APF.

  第二种方法即有源注入的方案，该方法选出接地故障的线路，借鑒有源电力滤波的理念来实现零残流。

• First the zero sequence transient current signal sampled is enhanced, and then the signal enhanced is decomposed by using wavelet packet analysis to realize faulty line detection.

  首先对采样的零序暂态电流信号做增强处理，然后利用小波包分析方法进行故障选线。
