摘要
在介绍了单端和双端行波法故障测距原理的基础上 ,着重讨论了诸如母线、行波源、过渡电阻等因素对行波测距的影响 ,并在理论上对每种算法的测距误差进行了分析。最后根据小波变换模极大值理论实现了行波测距 ,大量仿真表明 。
First, the theory of traveling wave fault location using one- and two-terminal data is introduced in this paper. Then many facts such as bus, source of traveling wave and transient resistance are taken into account in fault location. And the error of every location is calculated in the theory. Finally, a traveling wave fault location method is presented by using the theory of wavelet transform modulus maxima. Lots of tests show that the method is accurate.
