风力机运行过程中气动载荷变化工程分析
Variation of aerodynamic load engineering analysis during wind turbine run
摘要
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.关键词
