摘　　要：本文考虑实际环境中风能方向集中的特性,提出一种偏心型半潜式基础,采用AQWA-Fast软件建立风机全耦合分析模型,对比分析对称型风机和偏心型风机在不同风浪入射角下的运动响应特性。结果表明:波浪入射角变化几乎不影响漂浮式风机平均运动响应值和平均发电功率;当风浪入射角相同时,偏心型平台横荡、横摇和艏摇自由度运动性能更优,并在一定程度上降低了系泊张力;当波浪入射角不断变化时,偏心型设计将改善横荡、横摇、纵摇和艏摇运动性能;此外,偏心型风机综合发电性能更好。An eccentric semi-submersible foundation was proposed considering the characteristic of wind energy direction concentration in actual environment.AQWA-Fast software was used to establish the floating wind coupling analysis model,and the kinematic response characteristics of symmetric and eccentric wind turbine were compared and analyzed under different incident angles of wind waves.The results show that the variation of wave incidence angle hardly affects the average motion response value and average power generation of the floating wind turbine.When the incident angles of wind and wave are the same,the eccentric platform has better motion performance in terms of sway,roll,and yaw degrees of freedom,and to some extent the mooring tension is reduced.When the wave incidence angle constantly changes,the eccentric design will improve the motion performance in terms of sway,roll,pitch,and yaw degrees of freedom.In addition,the eccentric floating wind turbine has better comprehensive power generation performance.
