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。
Based on the deep analysis of the wind shear and tower shadow effects of the three-blade windward horizontal axis wind turbine, the wind speed dynamic model of the entire wind turbine swept surface is obtained. The influences of hub height, hub wind speed, wind shear coefficient, blade radius, tower radius and overhanging distance on the calculation model are considered. A 2MW wind turbine is calculated and compared. In order to further study the influence of wind turbine Independent pitch, power control, fatigue, dynamic stability laid the foundation.
