| 摘 要： | 提出一种用于降低风轮不平衡载荷的比例-积分-谐振独立变桨距控制策略,该控制器由比例-积分控制器和谐振控制器两部分组成,其中比例-积分控制器用于抑制不平衡载荷的1p(风轮旋转频率的倍数)分量,谐振控制器则用于抑制不平衡载荷的高频分量(2p、4p)。采用FAST软件对所提出的控制策略进行了仿真验证,仿真结果表明所提出的控制策略可以在传统比例-积分控制的基础上,进一步降低风轮所承受的高频不平衡载荷。

| Abstract: | A PI-R(Proportional-Integral-Resonance) individual pitch control strategy is proposed to reduce the unbalanced loads of wind turbine. Its controller consists of two parts: PI controller and R controller. The former is used to restrain the 1p(multiples of the rotor rotating frequency) component of the unbalanced loads while the latter the 2p and 4p components. The proposed control strategy is simulated with FAST software and the simulative results show that, the high-frequency unbalanced loads exerted on the wind turbine based on the traditional PI control is further reduced by the PI-R control. |
