巨大的深水风力资源代表了使用海上浮动风力涡轮机为世界大部分地区提供可再生能源的潜力。已经提出了许多漂浮式风力涡轮机的概念，但是需要考虑风力涡轮机的风流入、空气动力学、弹性和控制、沿着入射波、海流、流体动力学以及漂浮物的平台和系泊动力学的动力学模型来确定它们的技术和经济可行性。这项工作提出了一个全面的模拟工具的开发，模拟海上浮动风力涡轮机的耦合动态响应和验证的模拟工具，通过模型对模型的比较。完全耦合的时域气动-液压-伺服弹性仿真工具的开发具有足够的复杂性，以解决以前研究的局限性，并具有对各种转子-机舱组件、塔架、支撑平台和系泊系统配置进行载荷分析所需的功能。开发的流体动力学模块占线性静水恢复，非线性粘性阻力;增加的质量和阻尼的贡献，从线性波辐射，包括自由表面记忆效应;和在规则或不规则的海洋线性衍射的入射波激发。所开发的系泊缆模块是准静态的，并且考虑了具有海底相互作用的均匀拉紧或松弛悬链线阵列的弹性拉伸。通过与其他模型（包括频域模型）的结果进行比较，对流体动力学模块、系泊模块和整体仿真工具进行了测试。所有核查工作的有利结果为进行更彻底的分析提供了信心。版权所有（C）2009约翰威利父子有限公司
The vast deepwater wind resource represents a potential to use offshore floating wind turbines to power much of the world with renewable energy. Many floating wind turbine concepts have been proposed, but dynamics models, which account for the wind inflow, aerodynamics, elasticity and controls of the wind turbine, along with the incident waves, sea current, hydrodynamics, and platform and mooring dynamics of the floater, were needed to determine their technical and economic feasibility. This work presents the development of a comprehensive simulation tool for modelling the coupled dynamic response of offshore floating wind turbines and the verification of the simulation tool through model-to-model comparisons. The fully coupled time-domain aero-hydro-servo-elastic simulation tool was developed with enough sophistication to address limitations of previous studies and has features required to perform loads analyses for a variety of rotor-nacelle assembly, tower, support platform and mooring system configurations. The developed hydrodynamics module accounts for linear hydrostatic restoring, non-linear viscous drag; the added-mass and damping contributions from linear wave radiation, including free-surface memory effects; and the incident-wove excitation from linear diffraction in regular or irregular seas. The developed mooring line module is quasi-static and accounts for the elastic stretching of an array of homogenous taut or slack catenary lines with seabed interaction. The hydrodynamics module, the moorings module, and the overall simulation tool were tested by comparing to results of other models, including frequency domain models. The favourable results of all the verification exercises provided confidence to perform more thorough analyses. Copyright (C) 2009 John Wiley & Sons, Ltd.
