PMSG_forWindPower_GeneratorSide
对机侧系统的仿真包括系统模型的搭建、化简和控制算法的设计。直驱式永磁同步风力发电系统的机侧模型包括风力机模型、永磁同步电机模型和机侧PWM变换器模型。永磁同步电机和机侧PWM变换器模型的数学模型可以化简在一个数学方程中，简化方框图的搭建。控制器的设计目标是控制同步电机的转速实现最大风能的跟踪。(Simulation of the machine side of the system, including structures, simplification and control algorithms designed system model. Direct-drive-side model of permanent magnet synchronous wind power generation system includes a wind turbine model, permanent magnet synchronous motor model and machine-side PWM converter model. Mathematical model of permanent magnet synchronous motors and machine-side PWM converter model can be simplified in a mathematical equation, a simplified block diagram of the building. The controller is designed to control the synchronous motor speed to achieve maximum wind power tracking.)
