摘　　要：针对二极管箝位式3电平PWM整流电路拓扑结构和直驱型风力发电系统的特点,介绍了3电平空间矢量脉宽调制(SVPWM)的基本原理,建立了3电平永磁同步发电机在旋转坐标系下的数学模型,分析了电流转速双闭环控制策略,并对3电平整流器控制系统及SVPWM调制脉冲的产生进行了仿真.结果表明:3电平永磁同步电机SVPWM整流技术能够有效地控制转速,稳定系统直流电压.In view of the applications of diode-clamped three-level PWM rectifier in the permanent magnet direct drive wind power system are presented,and this rectifier topology and direct drive wind power system characteristics are introduced.The basic principles of the three-level space vector pulse width modulation（SVPWM） are described,the mathematical model of three level permanent magnet synchronous generator in rotating coordinate system is established to analyze the current speed double closed-loop control strategy,and three-level PWM rectifier model and its modulation current pulse generation are simulated.The results show that the technology of permanent magnet synchronous motor based on the three-level PWM rectifier can control the speed,stabilize the direct current voltage of power system effectively.
