摘要
回顾了行波保护的历史并综述了国内外研究现状 ,讨论了早期行波保护所存在的问题和原因。针对这些问题提出了相应的解决措施 ,包括利用小波变换分析行波的故障特征 ,研究行波保护新原理 ,把光互感器、DSP技术应用于行波保护系统等 。
The history of the travelling wave protection is reviewed. The status quo of the research is summarized. and themain problems existing in the protection are discussed. Against these problems, the corresponding solutions have beenproposed. The solutions include: applying the wavelet transform to the analysis of the fault feature of the travelling waves,studying new principle of the protection. and adopting the optical transducer and DSP technique in the protection system.This project is supported by National Natural Science Foundation of China (No. 59877020).
