摘　　要： 基于片条理论建立了水平轴风力机气动性能计算模型,考虑叶尖损失、轮毂损失、叶栅理论及失速状态下动量理论的失效对片条理论进行了修正,并且考虑了风剪切、偏航、风轮的结构参数和风力机安装参数对计算模型的影响,使得理论模型更接近于实际工况中的风力机。应用所设计的气动性能计算程序对一台1.3MW的失速调节风力机进行了气动性能计算,与国外大型商业软件的计算结果取得了良好的一致性,从而验证了模型的正确性和实用性。 A horizontal axis wind turbine aerodynamic performance prediction model based on strip theory was presented for supporting the design and validation of wind turbines. To account for tip loss, hub loss, cascade effects and the invalidation of momentum theory during the operation of the wind turbine operating in stall state, the strip theory was amended. The wind shear, yawing, structural parameters and installation parameters are taken into account to make the theoretic model more close to the wind turbine in operation. The aerodynamic performance of a 1.3MW stall-regulated wind turbine was calculated using the developed program. The calculation results are in good agreement with that pbtained by commercial software “Bladed for windows”.
