摘要: 为提高风力发电机组设计可靠性,需得到风力机在实际运行过程中叶片气动载荷的计算方法.从工程角度出发,对风力发电机使用的NACA专用翼型进行分析,结合薄翼理论推导出攻角变化特点,并依据风切变理论和塔影效应得到风力机实际运行时叶片在各个位置点的气动载荷.依据实际情况对风轮受力平面进行工程简化,得到风力机叶片气动载荷的计算方法.将此方法计算出的气动载荷与试验测量结果进行比对,吻合度较好.

Abstract: To improve design reliability of wind turbine, it needs the calculating method of aerodynamic load during wind turbine run. NACA special airfoil of wind turbine was analyzed based on the project. Combined with thin theory, airfoil angle of attack variation was deduced, meanwhile wind turbine actual force was calculated in each blade location point when blade of wind turbine was running based on wind shear theory and tower shadow effect. According to actual condition calculation method was engineering simplified, aerodynamic load calculation method of wind turbine blade was obtained. By this method aerodynamic load which was calculated match with experiment result, it fits better.
Key words: downwash velocity    thin-ting theory    equivalent angle of attack    wind turbine    aerodynamic load    tower shadow effect
