中文摘要：

为了研究风力机叶片参数化集成表达的方法,基于翼型型线集成理论与Bezier曲线拟合方法,建立了风力机叶片翼型、弦长和扭角分布集成表达的控制参数模型。通过风力机气动和噪声计算模型,研究了拟合风力机叶片的气动和噪声收敛特性。结果表明,本方法所得到的控制参数对应表达的拟合风力机叶片在功率、载荷和噪声等变化曲线与原风力机吻合一致,满足收敛的精度要求。

英文摘要：

In order to study of the general method for the intergrated representation of the wind turbine bladeparameters, the integrated expression of control parameters model of airfoil, chord legnth and twist angledistribution was established based on the airfoil profile integration theory and the Bezier curve fitting method. Theconvergence properties of fitting wind turbine blade was studied by the wind turbine aerodynamic and noisecalculation model. The research shows that corresponding wind turbine of control parameters which obtained by theproposed method in the paper is in good agreement with the original one, therefore in terms of power, load andnoise meet the accuracy requirements of convergence.
