This paper presents the simulator study of a two-terminal HVDC system. The various AC system faults to which the study system is subjected are a) remote-three-phase ground fault, b)single-phase-ground fault and three phase ground faults. These faults are applied both at the rectifier and inverter ends. The results of the simulator study are presented to demonstrate the controller performance in the recovery of HVDC link following AC system faults.
