摘　　要：通过在风力机的叶尖上添加V型平板小翼,可以提高风力机的输出功率。根据风洞实验,得到不同小翼风力机的功率特性曲线,利用WAsP软件对内蒙古6个地区10a的风能资源进行评估,模拟计算不同叶尖小翼风力机发电量,分析比较出不同小翼风力机在实际风场中的发电量的增大效果。结果表明:与无小翼风力机对比,单位面积发电量、发电量平均增加率最大的小翼为V6.8×3.2,其中该小翼在6个风场中发电量最大增加量为8%,发电量最小增加量为3%,同时该小翼也是功率放大最优小翼。An experiment of adding a V type tip vane to the blade of horizontal axis wind turbine was carried on. It can improve the output power of wind turbine. According to wind tunnel experiments, the power curves of wind tur- bine with different tip vanes were obtained. In six regions of Inner Mongolia, ten years of wind energy resource were evaluated by using the WAsP software. The power capacity of wind turbine with different tip vanes were calculated, analyzed and compared in the actual wind farm. The results showed that V6.8 × 3.2 is the tip vane which is the maximum power capacity per unit area and the average rate of increase of the maximum power capacity. Its maxi- mum power capacity increases 8% and its minimum power capacity increases 3%, while the tip vane is the best tip vane of power amplifier.
