To effectively suppress the overvoltage of HVDC receiving end system caused by the fault elimination, a coordinated control strategy of synchronous condenser and inverter side extinction angle is proposed. A reactive power regulator (QPC) is added to the conventional control system with a fixed extinction angle at the inverter side for realizing the reactive power control of the converter station by adjusting extinction angle at the inverter side, and at the same time coordinating the reactive power regulator parameters of both the synchronous condenser and the DC control system. The numerical simulation model of HVDC system with the synchronous condenser is built based on the PSCAD/EMTDC environment. The simulation results show that the coordinated control method can effectively reduce the overvoltage of HVDC receiving end system after the accident occurrence and speed up the recovery time of the AC system voltage.
