The wind power industry has witnessed a growing demand for cleaner energy resources, with an increasingly strong aspiration to provide the world with a low-cost and low carbon footprint energy source. Cost effectiveness has been the primary driving force in making wind power competitive compared to fossil fuel energy generation. Wind turbine substructures are among the most expensive and intrincate parts of the wind turbine, typically constructed using different materials such as concrete or steel. With sizes that vary depending on the specific turbine model and site conditions, substructure can extend several meters in diameter and tens of meters in height. With these substantial structures, the aerodynamic loads and structural damping becomes an increasingly critical feature to analyze. The accurate modelling then is crucial for optimizing the performance and stability of substructures in wind power systems and in order to expedite the design process, the development of surrogate models holds great importance. Surrogate models, created through data-driven and physics-based approaches, can approximate the behavior and response of substructures allowing for faster evaluations and iterations. By utilizing surrogate models, engineers can save time and resources, accelerating the design optimization and decision-making processes in wind power projects.

风电行业对清洁能源的需求不断增长，为世界提供低成本、低碳足迹能源的愿望日益强烈。与化石燃料发电相比，成本效益一直是风力发电具有竞争力的主要驱动力。风力涡轮机下部结构是风力涡轮机最昂贵、最复杂的部件之一，通常使用混凝土或钢材等不同材料建造。下部结构的尺寸根据特定涡轮机型号和现场条件而变化，其直径可以延伸数米，高度可以延伸数十米。对于这些实体结构，空气动力载荷和结构阻尼成为越来越重要的分析特征。准确的建模对于优化风力发电系统子结构的性能和稳定性至关重要，为了加快设计过程，代理模型的开发非常重要。通过数据驱动和基于物理的方法创建的替代模型可以近似子结构的行为和响应，从而实现更快的评估和迭代。通过利用替代模型，工程师可以节省时间和资源，加速风电项目的设计优化和决策过程。
