摘要
论文就我国高压线路的故障测距方法进行了分析比较,最后确定采用基于双端的行波测距法。由于现用的行波测距法在实际使用中存在一些制约因素,提出了使用小波变换技术及行波测距装置校验仪使问题得以改善。综合经济性、可实现性等因素,行波测距方法具有可靠性强、测距精度高等特点,完全不受故障类型、过渡电阻和系统参数的影响。
In this paper, the fauk ranging methods of China＇s high voltage transmission line are analyzed and compared, finally determined the method based on double terminal traveling wave fault ranging. As a resuk of the traveling wave fault ranging method has some restricting factors in practical application, put forward to use wavelet transform technique and travelling wave fault ranging device tester to improve the problem.From the view of economy and realization,the method of traveling wave fault ranging has the advantages of high reliability, accurate, unaffected by the type of fault, transition resistance and system parameters completely.
