摘要

为适应复杂多变的海上环境,高效利用风资源、减少用钢成本,开展漂浮式风电机组塔筒的结构优化设计。以船载风电机组为研究对象,引入漂浮式基础的动态响应,作为影响塔筒弯曲变形的重要约束条件。在保证风电机组稳定功率输出的前提下,以质量最轻为优化目标,以塔筒构造要求和规范为基本约束条件,建立漂浮式基础风电机组塔筒的数值优化模型,并利用遗传算法完成了模型优化。结果显示,在保证风电机组稳定性和正常功率输出要求下,塔筒的质量降低了35%,刚度提高了25%。

Abstract

To adapt to the complex and changeable offshore environment, optimize the tower structure of the floating wind turbine unit to efficiently utilize wind resources and reduce steel costs. Taking a ship-mounted wind turbine as the research object, the dynamic response of the floating platform is introduced as an important constraint condition that affects the bending deformation of the tower. The numerical optimization model of the floating platform wind turbine tower is established to achieve the goal of optimizing minimum weight, with tower construction requirements and regulations as basic constraint conditions, and the genetic algorithm is used to optimize the model. The optimization results show that the optimized results reduce the mass of the tower by 35 % and increase the stiffness by 25% under the premise of ensuring stable power output.
