为提高输电线路故障测距的可靠性,提出一种基于改进正交匹配追踪(orthogonal matching pursuit,OMP)算法的输电线路故障测距仿真方法。通过选择EMTP仿真软件作为故障测距仿真处理软件,利用全波傅氏算法构建信号滤波器,完成对原始信号的处理。引入改进OMP算法完成故障测距,得到故障测距仿真结果。结果表明,所提方法对于输电线路多种故障类型测距、不同故障位置的仿真效果表现较好,可提高输电线路故障测距的可靠性。

In order to improve the reliability of transmission line fault location,a simulation method of transmission line fault location based on improved orthogonal matching pursuit(OMP)algorithm was proposed.By selecting the EMTP simulation software as the fault location simulation processing software,the signal filter was constructed by using the full-wave Fourier algorithm to complete the processing of the original signal.The improved orthogonal matching pursurit(OMP)algorithm was introduced to complete the fault location,and the simulation results of the fault location were obtained.The results show that the proposed method has good performance in the simulation effect of multiple fault types and different fault locations of transmission lines,and can improve the reliability of transmission line fault location.
