风力发电机叶片设计及优化研究

Research on Blade Design And Optimization Of Wind Turbine

针对占我国面积近50%地区的风能可利用区,只有发展新型适合低风速地区的风力发电技术,才能更加高效地开发利用这些广袤地域的风能,风力发电机中最重要的结构部件则是叶片,因此叶片的结构设计在风力发电技术中显得尤为关键。基于目前我国风力发电技术的初步发展和未来的良好前景,分析国内外风力发电的现状、风力机简介、风机叶片设计的空气动力学理论、风机叶片翼型及气动系数等理论体系和计算方法,进而提出风力机叶片的优化设计。

for the wind energy available area,which accounts for nearly 50%of the area of our country,only by developing a new type of wind power generation technology suitable for low wind speed areas can we develop and utilize the wind energy in these vast areas more efficiently.the most important structural component of wind turbine is the blade,so the structural design of the blade is particularly critical in wind power generation technology.Based on the preliminary development of wind power generation technology in China and the good prospect in the future,this paper analyzes the current situation of wind power generation at home and abroad,the introduction of wind turbine,the aerodynamics theory of fan blade design,the airfoil shape of fan blade and the aerodynamic coefficient,and then puts forward the wind turbine blade optimal design of the sheet.
