变速变桨距风力发电机气动特性研究
Study on aerodynamic characteristics of variable-speed pitch-regulated wind turbine
摘要
Abstract
Based on the momentum-blade element theory,the influences of tip loss,taper angle,axial and tangential induced factor corrections are taken into account,then a iterative computational formula of velocity induced factor is deduced.Considered several factors that affect aerodynamic performance,a wind turbine computation model is established.Referring to the real turbine computation,the included factor,the force acting on blade distribution along the blade's outspreading direction and the effect of parameter variation such as pitch angle,rotate speed and tip speed ratio on aerodynamic performance are analyzed.On that basis,the methods of improving efficiency of wind energy and reducing load fluctuation are analyzed,and the foundation of dynamic design and operating characteristic analysis of wind turbine are laid.关键词
