摘要
基于模糊逻辑数学方法建立了风力机动态失速模型,用于计算风力机翼型的非定常气动载荷。以风力机翼型S809为算例进行了非定常气动载荷的计算。计算结果表明:基于模糊逻辑的动态失速模型得到的预测结果与试验数据吻合良好,且比Leishman-Beddoes模型具有更高的预估精度,能够捕捉风力机翼型动态失速的细节特征,从而证明了该方法的正确性和有效性。
Based on the fuzzy logic method, a new wind turbine dynamic-stall model is brought forward to calculate the unsteady aerodynamic loads of wind turbine airfoil. As a numerical example, the unsteady aerodynamic loads on S809 airfoil were calculated. The results show that the fuzzy logic model reconstructs the unsteady aerodynamic loads very well, and can capture the detail features of the dynamic stall of the wind turbine airfoils. Also, the comparison results show that the prediction accuracy is better than the Leishman-Beddoes model.
