【目的】研究不共线风浪对于浮式风机基础水动力性能的影响。【方法】利用OrcaFlex软件搭建10 MW风力机、半潜式浮式风机基础和系泊系统的全耦合模型，针对不同风浪夹角下的浮式风机进行数值模拟。【结果与结论】风向角变化对浮式风机基础运动影响较大，浪流角度的变化对风力机运动影响较小。风向角由0°变化到30°、60°、90°，风机发电效率分别降低11.61%、58.27%、81.69%；浪流角由0°变化到30°、60°、90°，风机发电效率分别降低0.23%、0.69%、0.91%，表明风向角变化会导致浮式风机发电效率明显减弱。
【Objective】To study the influence of non-collinear wind and wave on the hydrodynamic performance of floating fan foundation. 【Method】OrcaFlex software is used to build a fully coupled model of 10 MW wind turbine, semi-submersible floating fan foundation and mooring system; numerical simulation of floating fans under different wind and wave angles is carried out. 【Result and Conclusion】 The change of wind direction has great influence on the movement of floating fan foundation, and the change of wave and flow angle has little influence on the movement response of wind turbine. When the wind angle changes from 0° to 30° , 60° and 90° , the power generation efficiency of the fan decreases by 11.61%, 58.27% and 81.69%, respectively;When the wave angle and flow angle change from 0° to 30°, 60° and 90°, the power-generating efficiency of the fan decreases by 0.23%, 0.69% and 0.91% respectively. It shows that the change of wind angle will weaken the power generation efficiency of floating fan obviously.
