一种水平轴风轮叶片的气动设计方法

发展了两种先进的水平轴风轮叶片气动计算和设计方法－PROPGA和PROPID，PROPGA是基于最优化方法的遗传算法，用于最初的叶片选择和几何设计；PROPID是一种基于反问题的叶片气动设计方法，用于最后的叶片造型和性能预估。给出了两个实例，一个是以基础科学研究为目的实验探索用全新风轮，另一个则是用于商业生产的小型风轮。在实际风轮设计中的成功使用证明，PROPID和PROPGA是一种强有力的设计工具，两者的结合使用可以得到最佳的风力涡轮气动性能。

AN AERODYNAMIC DESIGN METHOD FOR HORIZONTAL AXIS WIND TURBINE BLADES

In this paper two advanced aerodynamic blade design methods were developed for horizontal axis wind turbines,namely PROPID and PROPGA.PROPGA is a genetic algorithm based on optimization method and is used for the tradeoff studies and preliminary blade designs while PROPID is based on an inverse design approach and is used for the final blade design stage and performance prediction.Two typical examples were considered in this paper,the first is a new blade set for an experimental wind turbine geared for fundamental research,the second is a commercial blade design for a small wind turbine.The successful application in design the wind turbine blades showed that the combination of PROPID and PROPGA provides an efficient technique for the aerodynamic blade design of wind turbines of any size.
