| 摘要: |
| 介绍了一种基于D型行波原理的T接线路故障测距方法，无需故障分支判断，计算简单。对T接线路故障时的行波过程进行了分析，直接利用故障时刻产生的初始波头到达T接线路三端的时刻，基于D型行波原理，进行两次双端故障测距，然后选择两次双端测距结果中的较大值作为最终故障测距结果。用ATP仿真软件和MATLAB软件对该方法进行了仿真分析。仿真结果表明，在T接线路发生故障时，此方法能够利用故障初期很短时间内的行波信号实现快速、准确的故障测距。 |

| Abstract: |
| On the basis of D-type traveling wave theory, a fault location method for T-connection lines is presented which doesn’t need judge fault branch and the calculation is simple. Wave progress in T-connection lines is studied, and based on D-type traveling wave theory, two double-terminal results are calculated by using the time that the first traveling wave head generated during the fault reaches the ends of the three-terminal power lines. Various situations are simulated and analyzed by ATP simulation software and MATLAB software. The simulation results show that this method takes advantage of the initial traveling waves within a short time to achieve fault location fast and accurately. |
