Load Control Under Yawed Condition for Wind Turbine

  • 摘要: 随着低风速风场的不断开发,低风速型风电机组面临叶轮尺寸不断增加和风况更加多变的情况。叶轮尺寸的不断增大带来了叶片柔性的增加,需要更加准确的仿真模型。而风况的多变导致机组长期处于偏航状态,进而导致叶片载荷波动的加剧,对机组寿命产生较大的影响。基于非线性耦合模型,提出了一种独立变桨载荷控制方法。非线性耦合模型采用了几何精确梁和自由涡尾迹方法,更适用于大尺寸叶轮的流固耦合效应的仿真。结果显示,提出的独立变桨控制方法不需要复杂的控制系统和额外的传感系统,即可以获得较好的降载效果。
