摘　　要：在对三桨叶上风向水平轴风力机的风剪切和塔影效应深入分析的基础上,得到了整个风轮扫掠面上的风速动态模型。并考虑了轮毂高度、轮毂风速、风剪切系数、叶片半径、塔架半径、悬垂距离等参数对计算模型的影响,对一台2MW风力机进行了计算和对比分析,为深入研究风力机的独立变桨、功率控制、疲劳、动力稳定性等奠定了基础。The wind speed dyanmics model in the whole rotor disk area is obtained , based on analysing wind shear and tower shadow for three-bladed upwind horizontal axis wind turbine. The hub height, the wind speed at hub height, the wind shear exponent, the blade radial distance, the tower radius and the overhang distance are taken into account, and the model is calculated and analysed for two megawatt wind turbine. These works lay foundation for the further study of the individual pitch, the power control, the fatigue and the dynamical stability for wind turbine.
