| Abstract: | 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). |
| Keywords: | transmission line travelling waves travelling wave protection wavelet transform |
