该研究针对中国海南万宁漂浮式风电场环境条件,对一种融合了半潜式和Spar两种平台优点的新型Triple-Spar浮式风力机平台的动力响应特性进行了深入分析。基于ANSYS AQWA商业软件,建立了浮式风力机的物理数值模型,系统研究了在均匀流和剪切流两种情形下,风浪流联合作用对平台系泊系统与风力机基础运动响应的影响规律。研究结果表明,在南海风电场环境条件下,Triple-Spar平台在垂荡方向上表现出优异的运动性能,但剪切流的作用使其在垂荡和纵摇方向的响应产生显著变化,对平台的稳定性和安全性提出新的挑战。该研究为中国海上风电场的平台设计和运行提供了重要的理论参考和数据支持。
Abstract
This study conducts an in-depth analysis of the dynamic response characteristics of a novel Triple-Spar floating wind turbine platform, which integrates the advantages of both semi-submersible and Spar-type platforms, under the environmental conditions of the floating wind farm in Wanning, Hainan, China. Using the commercial software ANSYS AQWA, a numerical model of the floating wind turbine was developed to systematically investigate the effects of combined wind, wave, and current forces on the mooring system and platform motion response under both uniform and shear flow conditions. The results indicate that, under the environmental conditions of the South China Sea wind farm, the Triple-Spar platform demonstrates excellent motion performance in the heave direction. However, the presence of shear flow induces significant variations in the heave and pitch responses, posing new challenges to platform stability and safety. This study provides valuable theoretical insights and data support for the design and operation of offshore wind farms in China.
