摘　　要：介绍了一种行波定位方法,将行波反射信号进行小波包分解与重构处理,构造特征矩阵,利用大矩阵来确定故障区段。比较故障线路和正常线路波形,使两波形相减,利用波形差第一个畸变点来确定故障距离。A kind of traveling wave fault-location method is introduced in this paper, the reflected signal of traveling wave is treated through wavelet packet decomposition and reconstruction, structuring characteristic matrix and using big matrix to determine the fault section. Contrasting the waves reflected from the fault line and the normal one, and subtracting this two waveforms, then the fault distance is determined by finding the first distortion point.
