本文针对某一特定海域，设计了10 MW海上风力发电机组（OWT）的单桩结构，并开发了一种新的土-结构相互作用（SSI）框架，用于气动-伺服-水弹性代码FAST。以DTU 10 MW OWT为原型，研制了叶片式控制器，实现了对转子转速和桨距角的调节，并与DTU原控制器进行了性能比较。随后，利用非线性Winkler基础模型建立FAST的SSI分析模型，并利用GL-Bladed软件的分析结果对该模块进行了验证。此外，该10mw OWT的单桩采用北海的海洋气象数据，设计用于层状砂。本课题采用软-硬设计思想，系统的一阶固有频率为0.22 Hz，位于OWT的1P和3P频段中间。此外，采用全耦合模型对该10 MW单桩支撑OWT的动力响应和疲劳损伤进行了研究。结果表明，SSI效应和时变桨距角对单桩的动力响应和疲劳寿命有显著影响。
In this study, the monopile of a 10 MW offshore wind turbine (OWT) is designed for a specific ocean site, and a new soil-structure interaction (SSI) framework is developed for the aero-servo-hydro-elastic code FAST. Taking the DTU 10 MW OWT as the prototype, a Bladed-style controller is developed to regulate the rotor speed and blade-pitch angle, and its performance is evaluated by comparisons with the DTU original controller. Subsequently, an SSI analysis model is established for FAST using the nonlinear Winkler foundation model, and this module is verified by the analysis results obtained from GL-Bladed software. In addition, the monopile of this 10 MW OWT is designed for layered sand adopting the metocean data from the North Sea. The soft-stiff design philosophy is used in this task, and the 1st-order natural frequency of the system is 0.22 Hz lying in the middle of 1P and 3P frequency bands of OWT. Besides, the dynamic response and fatigue damage of this 10 MW monopile supported OWT are investigated using the fully coupled model. The results show that SSI effect and time-variant blade-pitch angle significantly influence the dynamic response of OWT and fatigue life of the monopile.
