摘　　要：研究了一种用于直驱式风力发电系统的并网控制策略,建立了三相电压型PWM逆变器在三相静止坐标系和两相旋转坐标系下的数学模型,研究了其前馈解耦控制策略。在此基础上结合空间矢量调制(SVPWM)的算法,设计了三相电压型PWM逆变器控制系统,并在Matlab的Simulink中进行了系统仿真。仿真结果表明,设计方法可行,仿真模型正确。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.
