A novel differential protection scheme for HVDC transmission lines
International Journal of Electrical Power and Energy Systems, 2018 Abstract Based on the compensation of the distributed capacitive current, a novel differential protection scheme for HVDC transmission lines was proposed in this study. According to the analysis, after voltage and current signals at both sides of the line are processed by the same low-pass filter the cut-off frequency of which is low enough, then the
