Self-Protection of HTS Cable in VSC-Based DC Power Transmission System

HTS DC cable with its low loss, large capacity, small footprint, and environmental friendliness will become the direction of great potential for the development of power technology in the future. Under normal circumstances, due to the zero-resistance characteristic of superconductor, the transmission capacity of HTS DC cable is 3-5 times of that of conventional cable. In the case of a fault in the power system, the self-protection of the HTS cable can fault-limit the DC system.
