In this talk, traveling wave based fault location methods are introduced. Firstly, with multi-point measurement, continuous wavelet transformation (CWT) is introduced to capture arrival time of traveling wavefronts and the location logic in complex power network is proposed. Secondly, with only local measurement, the relationship between the fault location and polarity, intensity and arrival time of traveling wave is deduced under different power network topologies. The fault location method under velocity uncertainty is proposed with such information.
Xu Yun’an received his bachelor degree in Electrical and Electronic Engineering from ShanghaiTech University in 2021. He is currently pursuing his master’s degree in Electronic Science and Technology at ShanghaiTech University. His research interests include travelling wave based fault diagnosis methods in transmission lines.
