摘　　要： 为提高风力发电机组的运行效率,最大限度地将风能转换为电功率输出,风力发电机组必须变速运行。分析了无刷双馈电机的变速恒频风力发电机控制系统的模型,将自抗扰控制(ADRC)策略引入最大风能捕获控制,并在无刷双馈发电机有功与无功功率的解耦控制中,采用模糊控制器整定ADRC中非线性控制参数。仿真结果证明了ADRC具有比PID控制更小的超调量和更快的响应速度,验证了该控制方法具有很强的适应性和鲁棒性。 In order to improve the efficiency of wind generator and convert wind energy into output electrical power in maximum limit,wind generator must operate in variable speed mode. The model of variable speed constant frequency wind power generation control system with brushless doubly-fed generator（BDFG） was analyzed. The active-disturbance rejection control （ADRC） strategy was introduced to capture the maximal wind energy and realize decoupling control of active and reactive power of brushless doubly-fed wind power generation system. The nonlinear parameters of ADRC were designed with fuzzy control. Simulation showed that the system with ADRC has better dynamic performances,small overshoot and fast response than PI control system. The effectiveness,robustness and correctness of the proposed control strategy were verified.
