  摘要:在介绍永磁同步发电机(PMSG)d,q轴数学模型和矢量控制理论基础上,提出在直驱式永磁同步风电系统机侧采用PWM控制方式,通过转子磁场定向控制策略.实现有功无功功率解耦控制,减小了损耗,并且较好地控制了转速。利用Matlab/Simulink进行仿真,并给出了仿真结果。同时搭建了基于TMS320F2808控制器的试验平台,对该控制策略进行了实验,实验结果验证了该控制系统的正确性与可行性。

  Abstract;The PWM control strategy of directly—driven permanent magnet synchronous wind turbine sys—

  tern in motor-side was presented,which based on the dq—axis mathematical model of PMSG and the vector con—

  trol theory,by using the strategy of rotor field oriented,the active power and reactive power can be decoupled,

  while the loss can be decreased,and the rotor speed is controlled very well.Matlab/Simulink was carried out

  tO prove the validity of the system,and the simulating results was given.An experimental system based on

  TMS320F2808 was set up to verify the validity and the feasibility.

  Key words:directly-driven permanent magnet synchronous generators;vector control;rotor field oriented
