| 摘要: |
| 介绍了两种实用性较强的故障测距方法，一种利用小波变换的行波测距。另一种基于双端不同步数据的测距。着重对输电线路故障测距方法进行可行性验证，采用ATP仿真获得故障线路的电气量值，并用Matlab计算故障点的位置。 |

| Abstract: |
| Two widely applied methods of fault locating are introduced:the travelling wave fault locating with wavelet transform and the fault locating algorithm based on the unsynchronized data of two terminals. The verification of their feasibility is emphasized. The electric parameters are ac-quired by AT P simulation and the fault location is calculated with Matlab programming. |
