中文摘要：
研制了风力机专用试验平台并进行了验证试验,在此基础上,将该试验平台应用于1.5MW大型风力机1/16缩尺模型在12m×16m低速风洞的气动性能试验研究。通过对试验结果的分析,研究获得了桨距角对风能利用系数的影响规律,分析了不同叶尖速比下风轮转速急升和骤停现象与NH系列翼型气动特性的关系。论文还将试验结果与GH B laded软件计算结果进行了综合比较分析。研究表明,该风力机最大风能利用系数高于0.492。
英文摘要：
The wind turbine test platform was developed in the CARDC 12m×16m low speed wind twnnel and its dependability has been validated by test.Using this plat form the experimental investigation on the aerodynamic performance of a 1/16 scaled model of 1.5MW wind turbine was conducted.And aerodynamic performance of the full scale wind turbine was calculated by GH Bladed software.The influence of pitch angle on Cp and the relationship between the rapid raise and sudden stop phenomenon of turbine and the aerodynamic performance of NH airfoils are analyzed through the test data,which are also compared with the results calculated using GH Bladed.The test results show that the maximun power coefficient of the test model is 0.492 and this value should be higher for the full-scale wind turbine by consideration of the Reynolds number.
