| 摘 要： | 考虑了风速的威布尔(Weibull)分布,以年发电量最大为目标函数,运用遗传算法对某1.5 MW风力发电机叶片的气动性能进行了优化设计:将叶片沿展向分为13段,以每段的功率作为遗传算法的适应度函数.优化所得的气动外形参数体现了比Wilson方法和额定风速下的遗传算法更为合理的结果,弦长和扭角更趋于流线型分布,且扭角整体呈减小的趋势.

| Abstract: | The model based on genetic algorithm is applied to optimize the aerodynamic performance of a 1.5 MW wind turbine blades,and the objective function is annual energy production under the wind speed of Weibull distribution.The wind turbine blade is divided into 13 segments along the spanwise,and the power of each segment is used as the fitness function of genetic algorithm.The optimized aerodynamic parameters are more reasonable than those of the Wilson method and Genetic algorithm under rated wind speed,and chord length and torsion angle present a more streamline distribution and the torsion angle decreases overall. |
