摘　　要：浓缩风能型风力发电机提高了风能的品位,改善了风能的不稳定性,其能量转换规律具有特殊性。通过采用车载法对200W浓缩风能型风力发电机相似模型的流场进行测试,运用皮托管和数字压力计测试了各断面特征点的总压和静压,获取了能量转换特性。实验表明:在自然风场风速为10m/s,12m/s和14m/s时,中央圆筒的3个断面的能量分别增至相同面积的前方来流风能的2.49倍、2.27倍和2.20倍。The Concentrated Wind Energy Turbine heightens the quality of the wind energy and improves the instability of the wind energy. Its energy conversion has special characteristic. The flow field of resembled model of 200W ,concentrated wind energy turbine was tested outside in truck and the static pressure and total pressure of.special point in each section was tested by Pitot and Digital pressure gauge, and the characteristics of energy conWrsion was obtained. The test result showed that when the wind speed in nature flow field was 10m/s, 12m/s, 14m/s, the energy in three sections of center cylinder increased to 2.49, 2.27, 2.20 times respect of the equal area of natural wind flow.
