我们提出了一个新的优化框架开发的创新风力涡轮机叶片设计的调查。近几十年来，风力涡轮机的设计作为为风能生产提供经济上有竞争力的解决方案的持续努力的一部分而逐步发展。特别地，转子的尺寸已经增加，以便在限制安装成本的同时捕获更多的风能。同时，叶片设计者必须不断地提高叶片的结构效率，以便适应由于转子直径增大而产生的更高的极限载荷和疲劳载荷。现代风力涡轮机设计是这些渐进式改进的结果，限制了财务风险，但也限制了设计空间，并有效地减少了更激进创新的机会。在本文中，我们使更广泛的探索风力涡轮机叶片的设计空间，通过一个新的优化框架。为此，我们开发并联合收割机最先进的工具，用于风力涡轮机的气动伺服弹性分析和优化，旨在探索数十年增量变化带来的未知设计空间。我们的框架依赖于B样条曲面和层压参数的使用，以提供一个紧凑和连续的手段来描述叶片结构，还可以使用基于梯度的优化器。该结构参数化进一步与梁和壳有限元模型相结合，以进一步提高初步结构设计的可信度。本文提出并验证了所提出的框架。验证结果表明，与现代大型DTU 10 MW叶片设计的良好协议。此外，梁模型的耦合弯扭行为被发现与更高保真度的有限元模型预测吻合得很好。
We propose a new optimisation framework developed for the investigation of innovative wind turbine blade designs. The design of wind turbines has progressively evolved over recent decades as part of an ongoing effort to provide economically competitive solutions for wind energy production. In particular, rotors have increased in size so as to capture more wind energy while limiting installation costs. At the same time blade designers have had to continually improve the structural efficiency of blades in order to accommodate higher extreme and fatigue loads resulting from growing rotor diameters. Modern wind turbine designs are the result of these incremental improvements, limiting financial risks but also confining the design space and effectively reducing opportunities for more radical innovation. In this paper, we enable the wider exploration of the wind turbine blade design space by means of a new optimisation framework. For that purpose we develop and combine state-of-the-art tools for the aero-servo-elastic analysis and optimisation of wind turbines aiming to explore the uncharted design space resulting from decades of incremental changes. Our framework relies on the use of B-spline surfaces and lamination parameters to provide a compact and continuous means of describing blade structures, also enabling the use of gradient-based optimisers. This structural parameterisation is further combined with beam and shell finite element models to provide further confidence in preliminary structural designs. The proposed framework is presented and verified herein. Validation results show good agreement with the modern large scale DTU 10 MW blade design. Additionally, the coupled bend-twist behaviour of the beam model is found to agree well with higher fidelity finite element model predictions.
