摘要：
Converter in power control mode of MMC-HVDC(Modular Multilevel Converter based High Voltage Direct Current) system generally likes a negative resistance, which could reduce the damping of system, cause DC oscillation and reduce the system stability. The system power oscillation is restrained by contro-lling the superconducting magnetic energy storage device parallel connected to DC side, and the weak dam-ping problem caused by MMC-HVDC system supplying constant power load is solved. By building the small signal model of double-terminal MMC-HVDC system, the main factors affecting the stability of MMC-HVDC system are analyzed by small signal stability analysis method, and the effectiveness of the proposed DC oscillation mitigation method is verified. A double-terminal MMC-HVDC system model is built in MATLAB/Simulink and time-domain simulation is carried out. Compared with the control strategy by changing controller's power damping, the simulative results show that the proposed control strategy can effectively supp-ress system oscillation and improve system stability. © 2020, Electric Power Automation Equipment Press.
