【摘要】 针对VolturnUS-S半潜式平台与垂荡式波浪能转换器(WEC)集成系统,基于Orcaflex软件构建气动-水动-结构耦合数值模型,系统分析风、浪联合作用下集成系统的水动力响应与俘能特性。结合时域分析与功率输出系统阻尼优化策略,重点探讨了WEC集成对平台运动响应、系泊张力、风机动态响应及总发电功率的影响。研究表明,集成WEC显著提升了平台稳定性,并使平台总发电量最高提升6.2%; WEC集成对风机性能影响甚微,但额外捕获的波浪能可有效补充风力发电,尤其是在风机停机时提供持续电力输出。研究成果验证了风浪协同系统在增强深海能源开发稳定性与发电效率方面的潜力,为多能互补浮式平台的设计与优化提供了理论依据。更多还原

【Abstract】 This study investigates an integrated system combining the VolturnUS-S semi-submersible floating platform with heaving-type Wave Energy Converters(WECs). An integrated aero-hydro-structural coupled numerical model was developed using Orcaflex software to systematically analyze the hydrodynamic responses and energy capture characteristics of the hybrid system under combined wind and wave conditions.Employing time-domain analysis alongside Power Take-Off(PTO) damping optimization strategies, the research specifically examines the impact of WEC integration on platform motions, mooring line tensions,wind turbine dynamic responses, and total power generation. Key findings reveal that WEC integration significantly enhances platform stability and increases total power output by up to 6.2%. While the integration exerts minimal impact on wind turbine performance, the additional captured wave energy effectively supplements wind power generation. Notably, the WECs provide sustained power output during turbine shutdowns. These results validate the potential of synergistic wind-wave systems to enhance both operational stability and power generation efficiency in deep-water energy projects. The study provides an important theoretical foundation for the design and optimization of multi-source complementary floating platforms.更多还原
