摘要

以IEA-15 MW风力机为对象

基于非定常叶素动量理论模型和几何精确梁理论模型研究风剪切工况下叶片气弹耦合效应对大型风力机载荷特性的影响。结果表明：在风剪切工况下

风力机载荷呈类简谐波动

且叶片的柔性形变会导致风力机载荷降低。由于动态入流效应、翼型非定常气动特性以及叶片形变共同作用导致的风力机载荷响应延迟

会加剧风轮的偏航力矩。随着风剪切系数的增大

风力机的功率、推力以及风轮俯仰力矩和偏航力矩的均值和波动幅值增大

叶片载荷响应的迟滞也更加明显。

Abstract

Based on dynamic blade element momentum and geometrically exact beam theory

the effect of aerodynamic coupling effect on the load characteristics of IEA-15 MW wind turbines under wind shear conditions are studied in this paper. The results show that the wind turbine loads are similar to simple harmonics under the wind shear condition

and the flexible deformation of the blades will lead to the reduction of the wind turbine loads. Due to the dynamic inflow effect

unsteady aerodynamic characteristics of airfoil and blade deformation

the delay of wind turbine load response will increase the yaw torque of wind turbine. With the increase of wind shear coefficient

the mean value and fluctuation amplitude of wind turbine power

thrust

wind turbine pitch moment and yaw moment increase

and the hysteresis of blade load response becomes more obvious.
