| 摘 要： | 通过将小波变换与相模变换理论相结合，提出了电力电缆故障测距的方法，采用新的相模变换不仅可避免传统行波方法中存在受故障起始角影响的问题，而且单一模量能够反映所有故障类型．仿真结果表明，该方法有很高的测距精度，是可行的．

| Abstract: | By combining wavelet transform with the modal transform,a new method to locate the faults of a power cable is presented.The use of the new modal transform can not only avoid the influence of the breakdown outset angle existent in traditional traveling wave method,but also reflect all breakdown types by the sole module.The simulation results show that the method is feasible as it has a high accuracy in location. |
