输电线路双端行波故障测距新算法的仿真研究

New Fault Location Algorithm Based on Double Terminal Traveling Wave for Transmission Lines

常规双端行波故障测距原理简单,但受行波波速不确定因素的影响,容易出现较大的定位误差。在常规双端行波故障测距原理的基础上,推导出一种不受波速影响的双端行波故障测距新算法。M atlab仿真结果验证了该算法具有较高的定位精度。

The double terminal fault location method of traveling waves is simple, but the result is not accurate enough, which is caused by the uncertainty of wave speed. Based on the conventional double terminal fault location method, a double terminal fault location method avoiding wave speed influence is presented. The simulation results suggest that it has high accuracy.
