【摘要】 以DTU 10 MW风力机为研究对象，建立OO-Star半潜式平台漂浮式风力机模型，基于叶素动量理论和辐射/绕射理论分别求解风载荷与波浪载荷，模拟不同环境载荷方向下漂浮式风力机动态响应，对比分析不同环境载荷入射角度对其响应特性的影响。结果表明：湍流风入射角度对漂浮式风力机纵荡、纵摇及艏摇运动响应影响较大，而波浪入射角度对横荡和横摇运动响应影响较大，垂荡运动响应几乎不随湍流风和波浪入射角度改变而变化。随湍流风入射角度增加，漂浮式风力机平均发电功率急剧下降，而波浪入射角度对其平均功率几乎无影响。此外，系泊系统中1号系泊拉力随湍流风和波浪入射角度增大逐渐增加，2号系泊拉力逐渐减小，而3号系泊拉力则随湍流风入射角度增加先增大再减小，随波浪入射角度增大逐渐增加。更多还原

【Abstract】 Taking the DTU 10 MW wind turbine as the research object, the OO-Star semi-submersible platform floating wind turbine model is established, based on the blade element momentum theory and the radiation/diffraction theory to solve the wind load and wave load respectively, and the dynamic response of floating wind turbines under different environmental load directions is simulated, and the impact of different environmental load incident angles on its response characteristics is compared and analyzed. The results show that the incident angle of turbulent wind has a greater influence on the response of floating wind turbines to surge, pitch and yaw, while the incident angle of wave has a great influence on the sway and roll response. The heave response hardly changes with the turbulent wind and wave incident angle. As the incident angle of turbulent wind increases, the average power of floating wind turbines drops sharply, while the incident angle of waves has almost no effect on its average power. In addition, in the mooring system, the mooring tension of No.1 increases gradually with the increase of the incident angle of turbulent wind and wave, while that of No.2 mooring decreases gradually, while that of No.3 mooring increases first and then decreases with the increase of incident angle of turbulent wind, and increases gradually with the increase of incident angle of wave.更多还原
