| 摘 要： | 通过分析变速恒频风力发电系统风速与风力机功率的数学关系,提出了一种变速恒频风力发电最大功率捕获方法,并编写了风力机最优转速的设定程序,通过仿真验证了该方法的可行性和有效性。然后研究了变速恒频风力发电系统双馈电机励磁电流和转矩电流的解耦控制、最大风能捕捉与对双馈电机控制的要求,并针对双馈发电机的数学模型,建立了基于定子磁链定向矢量控制的变速恒频双馈风力发电系统最大功率捕获系统模型。

| Abstract: | A new simple control strategy of tracking the maximum power point in variable speed constant frequency(VSCF)wind-power generation system was proposed,through the analysis on the relationship between wind speed and power output of wind turbine.Then,the program of this method was designed.By this program,the feasibility of this strategy was testified.At last,a stator-flux oriented vector control model and a control system for tracking the maximum power point was built based on the investigation of the decoupling between the excited current and the torque current and the requirements on the doubly-fed induction generator control for tracking the maximum power point in variable speed constant frequency(VSCF)wind-power generation system. |
