| Abstract: | In this paper,the control strategy of high-performance three-phase grid-connected device for direct-drive wind power generation is researched,the mathematical models of the three-phase voltage-source PWM inverter in three-phase stationary coordinate system and two-phase rotating coordinate system are established respectively.The feedforward decoupling control strategy is studied.The control system of the three-phase voltage-source PWM inverter is designed based on the feedforward decoupling control strategy and SVPWM method.The simulation of the sytem is carried out with the software Matlab /Simulink and the simulation results verify that this design method is feasible and the simulation model is correct. |
