摘　　要：600W浓缩风能型风力发电机利用聚能装置把稀薄不稳定的自然风浓缩和均匀化之后发电,现已在内蒙古西部地区应用.通过对600W浓缩风能型风力发电机运行特性进行分析,结果表明:该机在自然风速为9.4m/s时达到额定转速,机组功率达到了794.08 W,年发电量是普通型风力发电机的1.98倍,风能利用系数为0.571.与普通发电机组相比,具有风轮直径较小,起动风速低,噪音低,风能利用系数较高和能够自动限速等特点.该机组导向平稳,运行安全可靠,应用前景广阔.The 600W concentrated wind-driven power generator utilizes an energy-gathering unit to concentrate and uniform thin and unstable natural wind for generating power, now the equipment has been applied in the west of the inner mongolia autonomous region. The operation characteristics of such power generator were analyzed, the result shows that, the generator reached the rated rotational speed when the natural wind speed became 9.4 m/s, the unit power reached 794.08 W, the annual power output is 1.98 times of that of ordinary type and the wind utilization co- efficient is 0.571. Compared to the ordinary type, the concentrated wind-driven power generator has the following merits ： smaller rotor diameter, lower starting speed, lower noise, higher wind power utilization coefficient and auto- matic speed limit etc. The guide of the generator set is steady, the operation is safe and reliable, the application prospect is broad.
