Research on a new scheme of LCC‐HVDC line protection
The Journal of Engineering, 2017 High‐performance protection scheme of the transmission line is very important for the safe and reliable operation of line commutated converter‐based high‐voltage direct current (HVDC) system. The transmission line protection scheme applied in existing projects is lack of reliability, rapidity and incomplete in theory.
