摘　　要：线路发生故障时,通过输电线路故障测距找到故障位置对输电系统的运行稳定性起到关键作用。为解决故障测距中不稳定的故障行波波速和较难识别的故障波头问题,提出基于Teager能量算子优化小波算法的输电线路故障测距方法。在MATLAB中搭建输电线路仿真模型,仿真结果证明了所提算法测距的准确性。When a fault occurs on a transmission line,locating the fault location through fault distance measurement plays a crucial role in the operational stability of the transmission system.To solve the problem of unstable fault traveling wave velocity and difficult to identify fault wave heads in fault location,a transmission line fault location method based on Teager energy operator optimized wavelet algorithm is proposed.Build a simulation model of transmission lines in MATLAB,and the results show the accuracy of the proposed algorithm for distance measurement.
