| 摘 要： | 根据永磁同步风力发电机的运行特性,构建以输出功率为反馈量、转速为控制对象的最大风能捕获控制模型,并在永磁同步发电机d,q轴数学模型和矢量控制理论基础上,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,对风速阶跃变化时机组运行情况进行了仿真,并给出了仿真结果。实验结果验证了该控制系统的正确性与可行性。

| Abstract: | According to the operating characteristics of permanent magnet synchronous wind power generator,build the maximum speed for the control model with a power output as the feedback vector,the rotational speed as the control object,and on the basis of permanent magnet synchronous generators d,q axis mathematical model and the vector control theory,achieve the active and reactive power decoupling control by the rotor field oriented control strategy,reduce losses and better control of speed.Simulate unit operation when the step change of wind speed by Matlab/Simulink and simulation results are given.Experimental results verify the correctness and feasibility of the control system. |
