| 摘 要： | 对现代D型双端和A型单端输电线路行波故障测距原理的准确性和可靠性进行了综合评价.在此基础上,提出了基于这两种行波原理的优化组合测距思想,并成功用于实际故障暂态行波分析.与单独的D型或A型行波测距方案相比,该方案能够利用A型行波原理对D型行波原理给出的测距结果进行验证和校正,提高了测距可靠性和准确性.实际应用表明,优化组合行波测距方案是可行的,并且测距性能得到明显提高.

| Abstract: | A general appraisal is given to the modern Type D double-ended and Type A single-ended transmisison line fault location principles based on travelling waves in accuracy and reliability.Based on this,an optimal combined fault location idea is presented based on the two types of travelling wave principles,and applied to the actual fault generated transient travelling wave analysis successfully.Compared with the separate Type D or Type A travelling wave based fault lcoation scheme,the most important virtue of ... |
