| 摘 要： | 谐振接地电网发生单相接地故障时，从故障初始行波产生原理入手，进行了初始行波的模量分析。并推导了初始行波在母线处的传播特性。与健全线路相比，故障所在线路初始零模电流行波幅值最大且极性相反。据此能检测故障线路。ATP仿真验证了其正确性。

Analysis of Single-phase Ground Fault Initial Traveling Waves of Resonant Grounded Grid |
| |
| Abstract: | As resonant grounded grid occur singl-phase ground fault, initial zero-mode current traveling waves are analysed, starting from the generation principle, with traveling wave propagation characteristics on the bus. Compared with healthy lines, the amplitude of zero＇mode current traveling wave of fault line is the biggest and has the opposite polarity. So, the fault line can be detected. ATP simulations prove the traveling wave analysis is correct. |
