    摘要:

    为了最大限度地利用风能,提高风力发电系统的效率,在分析变速恒频风力发电系统最大风能捕获原理的基础上,研究了一种不需要检测风速的最大风能补获功率控制策略,这种控制策略既可以实现双馈发电机系统低于额定风速下的最大风能捕获控制又可以实现变速恒频双馈风力发电机的有功、无功功率的前馈解耦控制。最后,利用Matlab/Simulink对不同风速下双馈发电机系统的运行性能进行了分析和比较,结果验证了该控制策略的正确性和可行性。

    Abstract:

    In order to utilize the wind energy most effectively and improve the efficiency of wind generation system, based on analyzing the control strategy of maximum wind energy capture for variable speed constant frequency wind turbines, a new control strategy is studied, which do not need to detect wind speed and can not only capture the largest wind energy beyond the maximum wind allowed, but also can realize decoupled control of the active power and reactive power of DIFG. Finally, the operational performances of the wind turbine system with DFIG with wind speed variation were analyzed and compared by using Matlab/Simulink. The results have shown the correctness and feasibility of the proposed control strategy. Keywords: VSCF wind energy generation system; maximum wind energy capture; power conditioning; decoupled control
