    摘要:

    针对行波故障定位方法中波速不确定性带来测距误差问题，提出一种新的避开波速和输电线路弧度的故障测距方法。首先，阐述利用多尺度小波变换对故障信号进行去噪的方法；然后，测量初始行波到达不同母线时的时间参数，进一步利用时间参数从故障距离表达式中消除输电线路波速和弧度的影响；最后，对比有/无变压器的故障定位结果。仿真结果表明，虽然有变压器时误差会偏大，但整体分析，该方法具有较高的精度和可靠性。

    Abstract:

    Aiming at the problem of fault location errors caused by the uncertainty of travelling wave velocity, this paper proposes a new fault location method that requires no wave velocity and transmission line radian information. Firstly, a denoise method through multi?scale wavelet transform for the fault signal is described. Secondly, the arrival time parameters of initial traveling wave at different buses are measured. Furthermore, the influences of wave speed and radian of transmission line are eliminated by those time parameters in fault distance expressions. In addition, this paper compares the different fault location results with and without transformers. The simulation results show that although the error will be larger when considering a transformer, this method has higher accuracy and reliability in most cases.
