为了开发深海风能资源,研究浮基风电平台在波浪中的响应特性,设计了一种半潜式浮基风电平台。应用ADINA软件,采用边界造波方法、ALE动网格方法以及网格变疏增大数值黏性的消波方法构建了数值波浪水池,对ITTC半潜式平台在规则波作用下动力响应进行了数值模拟,通过与该平台的模型试验数据进行比较,验证了数值模拟方法的准确性。而后对一种新型的浮基风电平台在波浪中的运动进行了数值研究,给出了风电浮基平台在不同水深、不同波高波浪周期情况下横摇、纵摇时程曲线。数值计算结果将有助于了解浮基风电平台塔架顶端的运动、位移和受力,为海上风机系统的设计提供合理的荷载参数。

In order to develop the deep sea wind power resources, the response characteristics of floating wind power platforms in waves are studied, and a semi-submersible type wind power platform is designed. Based on the ADINA software, the numerical wave tank is constructed through the boundary wave generation method, the ALD dynamic gird method and the wave absorption method of increasing numerical fluid viscosity through grid interval increasing. Numerical simulations on the dynamic responses of ITTC semi-submersible platform in regular waves are performed, and the accuracy of the numerical simulation method is validated through comparisons with model experimental result. Then, numerical studies are performed on the motions of a new typed floating wind power platform in waves, and the roll and pitch time histories of the platform in different water depth and different wave height-wave period combinations are presented. The numerical results will help understand the motions, displacements and forces of the tower top of the floating wind power platform, and provide reasonable load parameters for the design of offshore wind turbine systems.
