| 摘 要： | 分析了一种利用输电线路双端电气量进行精确故障定位的测距方法,该方法采用输电线路的分布参数模型,将线路故障看为正常运行状态和故障附加状态的叠加,基于等效序网,通过对称分量法求得故障附加状态下的各序故障分量,利用负序故障分量(三相对称故障采用正序故障分量)进行故障测距.在算法实现的关键环节分析了全波傅氏滤波算法.利用MAT...

| Abstract: | Analysis was made to a kind of distance measuring method to locate fault accurately using transmission line two-terminal electrical quantities.This method adopted distributed parameter model of transmission line,the fault state divided into normal operation and fault additional state.Based on transmission line's equivalent sequence network,the fault components of every sequence at the fault additional state were got through symmetrical component method.The negative sequence fault components(positive sequenc... |
