摘要
概念性地设计了一种新型半潜—Spar混合浮式基础,以5 MW水平轴风机为例,研究了该新型浮式基础支撑的浮式风力机系统的动力响应。基于三维势流理论和Morison公式,应用SESAM软件建立浮式基础模型,在频域内计算了该浮式基础的水动力参数和响应算子,分析了浮式基础的运动性能。考虑叶片气动载荷和浮式基础波浪载荷,应用FAST软件对风机—浮式基础系统进行时域计算,分析风力机系统的运动性能。结果显示,该浮式基础运动幅值较小,具有良好的运动性能。
A new semisubmersible-spar floating foundation is conceptually designed. Taking the 5 MW horizontal axis wind turbine as an example,the dynamic response of the floating foundation system supported by the new floating foundation is studied. Based on the three-dimensional potential flow theory and Morison formula,with the application of SESAM software,the floating foundation model is established,the hydrodynamic parameters and response operators are calculated in the frequency domain,and the motion performance of floating foundation is analyzed. Considering the aerodynamic loads on the blade and the wave loads on the floating foundation,with the application of FAST software,the wind turbine-floating foundation system is calculated in time domain,and the motion performance of wind turbine system is analyzed. The results show that the floating foundation has small amplitude and good motion performance.
