Aerodynamic Outline Designing and Aerodynamic Performance Evaluation for 1.5MW Horizontal Axis Wind Turbine

基于片条理论,建立了水平轴风力机的气动参数和性能计算模型,并考虑了叶尖损失、叶根损失、叶栅影响和重载荷下对片条理论参数的修正。以此为基础设计完成了某1.5 MW水平轴风力机叶片的气动外形,并对其气动性能进行了评估,结果表明该风力机叶片气动性能达到设计要求,具有较佳的风能利用系数和运转特性。

In this paper, the aerodynamic parameters and performance calculation model of a 1.5 MW horizontal axis wind turbine are set up based on the strip theory with necessary consideration to the necessary amendments to the theory due to the tip loss, the huh loss, cascade effects and the heavy load exerted. On the basis of the aforesaid work, the aerodynamic outline of the turbine blade is designed and its performance is evaluated. The result of the evaluation shows the performance meets the design requirements with a better availability coefficient and better operation features.
