摘要
为了最大限度地利用风能,提高风电机组的运行效率,在分析双馈发电机基本数学模型及其定子磁链定向的矢量控制技术的基础上,提出了一种实现双馈风电机组最大风能追踪的最优控制算法。利用Matlab/Simulink对不同风速下机组的运行状况进行了分析,仿真结果验证了该控制策略的正确性和可行性。
In order to most effectively utilize the wind energy and improve the efficiency of wind generation system,based on the analysis of the mathematic model of doubly fed induction generator(DFIG) and the vector control technology of stator flux linkage in DFIG, an optimal control algorithm was presented, realized maximum power point tracking. The operation of the system with wind speed variation were analyzed by using Matlab/Simulink. The results show the correctness and feasibility of the proposed control strategy.
