| 摘 要： | 10kV配电网结构复杂、分支众多,使单相接地故障定位问题难以解决。针对配电网的特点,提出了一种基于改进的C型行波法与直流信号注入法相结合的配电网单相接地故障定位方法。该方法利用不同定位方法的互补性来提高单相接地故障定位的有效性与准确性,实现了单相接地故障点的准确定位。经理论分析和ATP仿真表明,该方法能够快速准确定位出故障点。 |

| Abstract: | 10 kV distribution network structure is complex with many branches.It is hard to find the accurate location for single phase ground fault.A new distribution network single phase ground fault location method is proposed by combining modified C travelling wave and DC signal inject method based on distribution network characteristics.The method uses the complementarity of different location methods to improve the effectiveness and accuracy of single-phase ground fault location.The validity of proposed method i... |
