原始语种摘要: The mathematical model of grid-connected wave power generation system based on modular multilevel converter (MMC) is deduced with topology structure and the operation principle of the MMC analyzed in this paper. Then the corresponding current decoupling control strategy is obtained in dq coordinates. Simultaneously, averaging voltage control and voltage balancing control are used to control the MMC to solve the imbalance and the ripple of the capacitor voltage of sub-modules. Moreover, the double closed-loop control strategy is used to control the grid-side MMC. Finally, the simulation model of grid-connected wave power generation system based on MMC is built in Matlab/Simulink. The simulation is carried out to verify the effectiveness and feasibility of the proposed control strategy.
