Abstract
This paper describes the usefulness of new control method in HVDC link system which suffers from severe condition of weak ac system. The proposed control scheme is used for the positive feedback control which directly controlls dc current at dc link system. The object of this paper is to improve the transient response of HVDC link system in disturbances such as faults. To achieve this objective, digital time-domain simulations are employed by the Electro Magnetic Transient Program for DC system(EMTDC).
