Introduces the master control method and establishes transient mathematical model for VSC-MTDC. Designes the DC voltage controller and power controller based on the theory of auto-disturbance-rejection control , and realizes the purposes of full decoupling of active power and reactive power. The simulation results using MATLAB/Simulink show that changes of voltage in the AC system, short circuit faults and DC system active power or reactive power changes, DC power transmission system can achieve stable operation.
