Abstract

Wavelet transform has received greater attention in fault analysis due to its ability in analyzing the travelling waves than conventional methods of analysis. In this paper, the method using wavelet transforms for detecting a HVDC transmission line faults is proposed after simulating the HVDC system for various faults. The simulation results show that the application of wavelet technique leads to a more reliable solution for recognition of faults and provides a good basis for the new protection scheme for the HVDC lines.
