Voltage source converter based high voltage direct current (VSC-HVDC) system technique has been widely applied in the field of power transmission, system control strategy of VSC-HVDC system based on active disturbance rejection control (ADRC) is proposed aiming at low stability precision and weak anti-jamming capability issues of traditional PI control. The structure diagram of system control is designed according to mathematical model of VSC-HVDC system built, of which ADRC strategy is adopted in sending system and receiving system. The external loop of sending system adopts Fal function control and inner loop adopts PI control; the external loop of receiving system adopts DC voltage control and inner loop adopts current and reactive power control. At last, simulation experiment is conducted on controller designed through Matlab/Simulink, experimental results show that ADRC based controller, which has a better control performance, reaches stable state before 0.2~0.3 second compared with traditional controller.
