摘　　要：以叶素动量理论为基础,设计了传统3叶片式、加速装置3叶片式和加速装置4叶片式风力机3种构型,并获得3种风力机的气动和结构参数.提出了加速装置下风力机气动和结构参数设计方法.建立了3种构型风力机的空气动力学模型,计算得到其功率分布和年发电量分布.分析结果显示:在相同额定功率和年发电量的条件下,加速装置风力机风轮尺寸相对传统风力机减少了35%,风能利用系数提高1倍以上.得到了一种工作在加速装置下的高效风力机,为风力机的设计和开发提供了新思路和可靠的理论依据.Based on the blade element momentum（BEM）,three type wind turbines are designed. They are 3-blade traditional wind turbine,3-blade and 4-blade wind turbine under the wind velocity acceleration equipment（WTWVA）. Their aerodynamic and configuration parameters are obtained. The previously developed design technique is further developed for aerodynamic and structural parameters of WTWVA. Aerodynamic model is established for 3 type wind turbines. Power distribution and annual energy output are also calculated for analysis. The analysis results show that under the same condition of power and annual energy output,the radius size is reduced by 35% of new WTWVA and power coefficient is increased more than 1 time. Finally,an efficient wind turbine device is designed. Theoretical basis is reliable for design and development of new efficient wind turbine.
