摘要

中国海域对大型浮式风力发电机组的水深适应性、稳定性、结构完整性、动力响应特性和经济性等提出了较高的要求。本研究旨在提出10兆瓦(MW)半倾斜柱半潜平台(SPIC)中水深FWT概念,为大型FWT的概念设计提供指导。SPIC概念FWT采用部分向外倾斜的侧柱,有效地降低了触底风险,显著提高了浮动风力机的稳定性。这是通过增加水平面的惯性矩而不增加排水量或水面面积来实现的。10 MW SPIC概念FWT在较小的静倾侧角、运动振幅响应函数和波浪力传递函数方面表现出优越的性能。它还具有钢材消耗少,排水量少,稳定性好,水动力性能好,成本低的特点。实验结果验证了概念设计的合理性和数值模拟过程的准确性。研究评估了10mw SPIC概念FWT在发电、发电故障、停车状态和停车故障等不同工况下的六个自由度的极端响应,从而验证了SPIC概念的安全性。

Research on the conceptual design and performance analysis of a 10 MW SPIC concept floating wind turbine foundation in intermediate water depth
The sea area in China demands high requirements for water depth adaptability, stability, structural integrity, dynamic response characteristics, and economic performance of large-scale floating wind turbines (FWTs). The aim of the research is to propose the 10 megawatts (MW) SPIC concept (Semi-submersible platform with Partially Inclined Columns, SPIC for short) FWT in intermediate water depth, providing guidance for the concept design of large-scale FWT. The SPIC concept FWT incorporates partially tilted outward side columns, which effectively minimize the risk of bottom contact and significantly enhance the stability of the floating wind turbine. This is achieved by increasing the inertia moment of the waterplane without increasing the displaced water or water surface area. The 10 MW SPIC concept FWT exhibits superior performance in terms of smaller static heeling angle, motion amplitude response function, and wave force transfer function. It also features lower steel consumption and less displaced water, achieving good stability, hydrodynamic performance, and low cost. The rationality of the concept design and the accuracy of the numerical simulation process were validated in this study using experimental results. The study assessed the extreme responses of the 10 MW SPIC concept FWT in its six degrees of freedom (DOFs) under various scenarios, including power production, power production with faults, parked condition, and parked condition with faults, thus verifying the safety of the SPIC concept.
