输电线路故障行波的研究

Study on fault traveling wave of transmission line

本文首先介绍了输电线路行波的基本概念,产生原理,相关参量的计算方法。接着对输电线路行波进行仿真,利用Matlab/Simulink建立了系统仿真模型,得出故障点的三相电压电流波形。最后进行故障行波的提取,得到仿真后得到提取后的正向行波和反向行波的波形。

This paper introduces the basic concept of transmission line traveling wave, generation principle, calculation method of related pa- rameters.Then the transmission line traveling wave is simulated, and the system simulation model is established by using Matlab/Simulink.Finally, the fault traveling wave is extracted, and the forward and backward traveling wave waveforms are obtained after simulation.
