浓缩风能型风力发电机的整体模型风洞实验（第Ⅲ报）——发电对比实验

A Wind Tunnel Test on the Entirety Model of Concentrated Wind Energy Turbine (Report No.3)——The generated output power comparative test

摘要: 低速风洞内进行的实验结果表明：当风速为５．５０ｍ／ｓ时，浓缩风能型风力发电机模型的输出功率为１００Ｗ，是直径相等的普通型风力发电机（风力机和发电机的总机械效率为０．３３２时）的输出功率的３．８倍；其输出功率相当于目前我国草原上使用的小型风力发电机输出功率的６倍；并且该机组的起动风速比相同叶轮普通型风力发电机模型的起动风速低

Abstract: The test was carried out on the FD-09 low speed wind tunnel of the Beijing Institute of Aerodynamics. When the wind speed in tunnel is 5.50 m/s, the output power of the concentrated wind energy turbine model is 100 W which is 3.8 times of the output power of the ordinary wind energy turbine with same diameter and 6 times of the output power of the small sized wind energy electric generator commonly used in the prairie in China at present. And its starting wind speed required is lower than that required for the ordinary wind energy turbine equipped with same blades.
