摘要
在对大型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、悬垂距离等参数对风速计算模型的影响,对一台2MW风力机空气动力载荷进行计算和对比分析,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 was obtained, based on analysing wind shear and tower shadow for three-bladed upwind horizontal axis wind turbine. The aerodynamic data, the blade geometry parameter, the hub height, the wind speed at hub height, the wind shear exponent, the blade radial distance, the tower radius and the overhang distance were taken into account, and the aerodynamic load was calculated and analysed for 2MW 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.
