摘要
随着深远海风电开发的推进,漂浮式风机在位安装技术因其适应深水环境和经济性优势而备受关注。聚焦于在位安装过程中漂浮式风机基础的运动响应,研究波高、波浪周期和迎浪角对其运动幅值的影响,旨在为作业窗口的优化提供科学依据。采用基于AQWA数值模拟方法,结合JONSWAP谱模拟不规则波浪,系统分析27种工况下叶轮中心的水平和垂向运动响应。结果表明:波高和波浪周期是影响风机运动响应的主要因素,水平和垂向运动幅值随波高增加而线性增大,随波浪周期接近固有周期而显著放大;迎浪角和系泊链张力对运动响应影响较小。基于施工经验设定的运动阈值(水平运动≤0.5 m,垂向运动≤0.15 m),识别出适宜的波浪条件为波高≤1.25 m且周期≤7 s或波高≤1.5 m且周期≤6 s。研究为漂浮式风机在位安装工程实践提供理论指导,未来可结合风载耦合效应和试验验证进一步优化。
With the advancement of deep-sea wind power development,the in-situ installation technology for floating wind turbines has gained significant attention due to its adaptability to deep-water environments and economic advantages.The motion response of floating foundations during the in-situ installation process was analyzed in this paper,with the effects of wave height,wave period,and wave angle on motion amplitude being examined to provide a scientific basis for optimizing operational windows.A numerical simulation method based on AQWA,combined with the JONSWAP spectrum to model irregular waves,was employed to systematically analyze the horizontal and vertical motion responses at the rotor center under 27 operating conditions.The results indicate that wave height and wave period are the dominant factors influencing motion response,with both horizontal and vertical motion amplitudes increasing linearly with wave height and amplifying significantly when the wave period approaches the natural period of the system.In contrast,wave angle and mooring chain tension have a relatively minor impact on motion response.Based on motion thresholds derived from construction experience(horizontal motion≤0.5 m,vertical motion≤0.15 m),suitable wave conditions for installation are identified as wave height≤1.25 m with a period≤7 s,or wave height≤1.5 m with a period≤6 s.The research provides theoretical guidance for the engineering practice of in-situ installation of floating wind turbines.Future research could further enhance these findings by incorporating coupled wind load effects and experimental validation.
