| 摘 要： | 首先利用Wilson方法进行叶片的外形初步设计,然后以设计攻角作为变量,以额定风速下功率系数最大为优化目标,建立了1 MW变桨距风力机叶片气动外形优化模型,采用遗传算法进行了优化再设计。通过对3叶片1 MW风力机进行的气动性能评价结果表明,优化后的风力机具有更好的气动性能,说明采用该优化方法进行变桨距风力机设计具有明显的优越性。

| Abstract: | The preliminary shape of the blade was designed by Wilson method,then setting the designed attack angles as a variable,the optimization model of a 1 MW pitch-variable wind turbine blade aimed at the maximum power coefficient under rated wind speed was established.The aerodynamic blade geometry was optimized by using genetic algorithm according to the model.Through the evaluation on the aerodynamic performance of 1 MW pitch-variable wind turbine,the results showed that the optimized wind turbine had a better... |
