A Novel Integrated Protection for VSC-HVDC Transmission Line Based on Current Limiting Reactor Power

In this paper, a novel integrated protection for VSC-HVDC transmission line is proposed. The protection scheme includes a main protection and a backup protection. The main protection is based on current limiting reactor power (CLRP), while the backup protection is based on variation tendency of current. The changing characteristics of CLRP and current are theoretically analyzed under different fau...
