At present, there are few literatures about the coordinated control of STATCOM and HVDC. A coordinated control strategy is proposed to balance the system stable and transient characteristics of STATCOM and HVDC. The control strategy includes steady-state voltage control, steady state constant reactive power control, transient control and interlocking control of 4 modes, and further inhibit the commutation failure of additional control transient control mode. Based on the actual engineering control logic and parameters, the HVDC PSCAD/EMTDC model with STATCOM on the inverter side is constructed. And the coordinated control strategy is simulated and verified under various conditions. Research shows that in the steady state conditions, the coordinated control strategy can reduce the voltage fluctuation, improving the system of voltage control accuracy. In the transient conditions, the coordinated control strategy can restrain commutation failure, improving the system recovery characteristics. And the dditional control can further play its positive role.
