Abstract

一种提高低流速的动力装置，尤其涉及一种提高低风速和潮汐流速的动力装置，可应用于低风速风力发电和潮汐流发电，属于动力或发电设备技术领域。提高低流速的动力装置含有至少两个风轮，风轮之间设置风挡装置(F1,F2,F3)，风挡装置(F1,F2,F3)两侧的风轮互为反向旋转且转向设置成使叶片(2)的出力方位区域在靠近风挡装置(F1,F2,F3)的一侧；其效果是风挡装置(F1,F2,F3)提高了流经叶片(2)出力方位区域的风速，从而提高了风轮的功率，显著提高了低风速的Cp。测试结果是低风速(2－10m/s)的风能利用系数Cp平均提高22％。提高低流速的动力装置结合低流速高效FW叶片(2)应用于风力发电，其低风速的发电量比现有技术的高3－4倍。
