摘　　要：内蒙古自治区偏远农牧区广泛使用的小型风力发电机无自动保护装置,发电系统可靠性差,经常发生烧毁事故。对此,以风轮吸收功率为理论研究基础,使用风向仪作为自动迎风系统的检测元件,过电压继电器为刹车系统的检测元件,提出一套控制小型风力发电机在正常风速下能够自动迎风,遇到强风自动刹车的电气控制电路,以期提高小型风力发电机发电效果,保证发电机运行可靠性。The small wind turbines widely used in Inner Mongolia Autonomous Region have no automatic protection device so that its power system reliability and frequent burnout accident often took place. In this regard, taking the wind wheel absorption power as its theoretical basis, using anemoscope detect wind direction and overvoltage relay determine whether brake, the author proposed that a set of electrical control circuit of small wind turbines can automatically windward normal wind speeds, encounter strong wind automatic braking to improve the effect of small wind generator and ensure the operation reliability of the generator.
