摘　　要： 风力发电机叶轮设计通常分为设计计算与性能验证两部分.对大功率风电机,在得到叶片的几何数据后,必须进行叶轮的气动性能验证计算.建立理论计算模型,以具体1.2MW风电机叶轮为对象,进行了理论计算和实际数据测试,并建立了仿真验证模型.结果显示,依据理论模型进行设计计算和验证计算时,要适当增大修正系数,保证理论设计与实际运行结果更加接近.在建立大功率叶轮仿真模型时要综合轮毂和叶尖损失,重视摩擦等因素的影响,使模型的仿真验证功能更强.大功率叶轮设计时必须将理论计算与仿真和试验验证相结合,保证设计结果更加符合运行实际. The design on wind turbine generator rotor is usually divided into two parts： design calculation and capability validation. The high-power wind generator must be given the validation of aerodynamic capability after the geometry data of the blade was obtained. Based on the theoretically calculated model, the theory calculation and practically data testing of 1.2 MW turbine rotor has been made. And simulation model was established. As a showing result, it is necessary to enlarge the amendatory coefficient properly and ensure the theory design reliability during the theoretically calculating and validating. The factors on losses of the hub and tip, the effect of friction, etc is synthesized to make the function of simulation and validation better. The theory calculation and simulation must be combined with the testing in the design processes of rotor to ensure the design result much more in accord with the running fact.
