考虑气动弹性的风力机叶片外形优化设计
Shape optimization design of a wind turbine blade considering aeroelastic effect
摘要
Abstract
In this paper, we establish a novel aerodynamic model that considers the influence of aeroelasticity. In this model, we introduce a new quantity-the twisting angle of a loaded blade. We also propose an optimization mod⁃el that maximizes the wind power coefficient at the wind speed is proposed for the pitch regulation wind turbine. We defined the chord length and twist angle distributions as design variables, and then established the mathematical op⁃timization model for considering aeroelasticity for an 850 kW wind turbine blade. Lastly, we designed a wind tur⁃bine blade using a genetic algorithm. The optimization results show that, compared with the reference blade, the maximum power coefficient of the optimized blade was improved, and the output power of the optimized blade in⁃creased at most by 23 kW while reducing the mass. This proposed design method provides a theoretical foundation for designing high⁃performance and low⁃cost wind turbine blades.关键词
