新型离网型风力机气动特性测试与分析

摘要

在低速风洞下对两种不同翼型的水平轴风力机进行气动特性实验研究,得到风力机的功率特性曲线；利用WAsP软件对当地风能资源评估,分析计算得到风谱图；最后计算两种不同翼型的风力机在不同地区风资源的单位面积年发电量.结果表明:在实际风场中采用新翼型风力机比传统翼型风力机单位面积发电量平均提高了28.4％.%Under the low speed wind tunnel, experiments were carried out to study the aerodynamic characteristics for two horizontal axis wind turbine of different airfoil, as the result, the authors got the power curve of wind turbine. Then, WAsP software was used to evaluate local wind energy resources, orderly to obtain the wind atlas through analysis and calculation. Finally, the annual energy production per unit area was calculated for two different airfoil wind turbine in different area. The results showed that in the actual wind farm the generating capacity per unit area of the new airfoil wind turbine increased 28.4% compared with the conventional wind turbine.
