抽象的。本文介绍了1/49比例SATH 10 MW INNWIND浮式平台波浪水槽试验活动的结果。软件在环（SiL）混合方法用于包括风力涡轮机推力和面内转子力矩My - Mz。实验结果与OpenFAST中开发的浮动风力涡轮机的数值模型进行了比较。水槽试验活动是在爱尔兰科克的Lir国家海洋TF的深海盆地试验的比例模型中进行的。Saitec采用这种浮动式下部结构设计，以支持ARCWIND项目中的10 MW INNWIND风力涡轮机，目的是承受欧洲大西洋地区的环境条件。CENER提供了专门为SATH 10 MW配置设计的风力涡轮机控制器。在这项工作中提供的实验装置，力致动器配置和数值气动参数的描述。在风和波浪载荷下的最相关的实验结果显示在时间序列和频域。文中还讨论了水下几何形状变化对俯仰固有频率的影响。本文显示了模拟的情况下，额定风速，其中被认为是倾斜的几何形状的水下子结构的流体静力学和流体动力学特性的计算。这种情况下，提供了一个更好的协议的俯仰自然频率与实验，比等效的模拟使用未移位的几何网格的计算的流体动力学和流体静力学性能。
Abstract. This paper describes the results of a wave tank test campaign of a 1/49 scaled SATH 10MW INNWIND floating platform. The Software-in-the-Loop (SiL) hybrid method was used to include the wind turbine thrust and the in-plane rotor moments My – Mz. Experimental results are compared with a numerical model developed in OpenFAST of the floating wind turbine. The tank test campaign was carried out in the scaled model tested at the Deep Ocean Basin from the Lir National Ocean TF at Cork, Ireland. This floating substructure design was adapted by Saitec to support the 10MW INNWIND wind turbine within the ARCWIND project with the aim of withstanding the environmental conditions of the European Atlantic Area region. CENER provided the wind turbine controller specially designed for the SATH 10MW configuration. A description of the experimental set up, force actuator configuration and the numeric aerodynamic parameters are provided in this work. The most relevant experimental results under wind and wave loading are showed in time series and frequency domain. The influence of the submerged geometry variations in the pitch natural frequency is discussed. The paper shows the simulation of a case with rated wind speed, where the tilted geometry for the computation of the hydrostatic and hydrodynamic properties of the submerged substructure is considered. This case provides a better agreement of the pitch natural frequency with the experiments, than a equivalent simulation using the undisplaced geometry mesh for the computation of the hydrodynamic and hydrostatic properties.
