摘　　要：　在介绍单端和双端行波法故障测距原理的基础上,着重讨论小波变换的基本理论及其模极大值理论在行波测距中的应用,提出故障暂态分量奇异性的基本判据和补充判据。大量的仿真表明,本方法有效且有很高的测距精度。On the basis of describing the principles of fault range finding with one and two-terminal traveling wave method, the paper mainly discusses the basic theories of wavelet transform and modulus maximal value which are applied in fault range finding of traveling wave. The elemental criteria and the additional criteria of fault generated transient components' strangeness are also put forward. Lots of simulations proves the validity and accuracy of the scheme presented in this paper.
