以风力发电项目为背景,基于三电平的电压空间矢量脉宽调制技术(SVPWM)的控制方法,对永磁同步电机进行了控制策略研究。详细讨论了建立永磁同步电机三电平SVPWM控制系统仿真模型的方法,在Matlab6.5/simulink中建立了永磁同步电机三电平SVPWM控制系统的模型,并进行了仿真实验,仿真结果表明永磁同步电机三电平SVPWM控制系统应用的正确性。

This paper, which is based on the background of the wind power generation, analyzes the theory of three-level vector control and studies the permanent magnet synchronous motor control strategy on the basis of the three-level voltage space vector PWM technology control method. Analyzes the method of establishing PMSM three-level SVPWM control system simulation and conducts the simulation experiments that the permanent magnet synchronous motor three-level SVPWM control system model was established in Matlab6.5/simulink. The simulation results show that the permanent magnet synchronous motor three-level SVPWM control system which is discussed in this paper is correct.
