The safe and stable operation of the HVDC transmission system greatly depends on the control system. The DC control system realizes a series of control strategies such as constant-current, constant-voltage, and constant-extinction angle control by controlling the trigger phase. The CIGRE Benchmark model is often used as a standard test model for research, but it is usually necessary to improve in actual project. First of all, taking the CIGRE Benchmark model as the research object, the DC control mode and basic control functions are introduced systematically. On this basis, the improved control strategy is studied. At the same time, PSCAD / EMTDC simulation software is used to build an improved control system model. The transient response of CIGRE Benchmark and improved control system is simulated and analyzed. Furthermore, the control mode conversion and control system response under different control strategies are studied.
