摘要
分析了双馈风力发电机的工作原理,建立了两相同步旋转坐标d-q下的数学模型。运用直接在控制电压处进行补偿控制的思路,提出了双PWM变换器新型协调控制策略。MATLAB仿真表明控制策略能够满足变速恒频的运行要求。
This thesis analyses the working principle of the doubly-fed induction generator（DFIG） and establishes the mathematical model in d-q synchronous reference frame. Based on the idea to compensate the control voltage directly,a novel coordinated control strategy,dual PWM converter coordinated control strategy is proposed. The MATLAB simulations prove that the control strategy can meet the operational requirements of VSCF.
