摘要
输电线路行波测距装置的应用,提高了输电线路的测距精度,对线路巡线和事故抢修非常有利,但行波测距装置在使用中仍然存在着一些问题,较为突出的是测距存在误差和无有效测距报告。文章对引起行波测距装置存在问题的原因进行了分析,并提出了改进措施。
The application of line fault location based on traveling wave greatly improves the accuracy of line fault location, and makes it convenient to search fauh and make urgent repairs. However, some problems still exist in the application of line fault location based on traveling wave,and location error and non-valid report frequently occur. This paper analyses the causes of the existing problems,and puts forward some solutions.
