摘  要:
垂直轴风力机风能利用率低的原因,是其在顺风一侧获得的能量,在逆风一侧又被消耗掉一部分。本定向高效垂直轴风力机的叶片在叶轮转动过程中也自转,通过调整叶片的迎风角度,在逆风一侧同样也能获得能量。使得定向高效垂直轴风力机的风能利用率提高到50%以上。通过定向机构,可确保叶片在风向改变时始终保持设计工况。定向高效垂直轴风力机风洞模型试验中,在风速5m/s时,无负荷时转速为300r/min。加负荷后,启动风速为5.2m/s,转速为90r/min。

摘  要:
The reason for the low wind energy utilization of vertical axis wind turbine is that the energy gained at the downwind side is partly consumed at the upwind side.The blade of the directional efficient vertical axis wind turbine rotates with the rotation of impeller.The energy can also be gained at the upwind side by adjusting the blade windward angle,and the utilization of wind energy is improved more than 50%.Through directional structure,the blade can keep design conditions when the wind changes.In the wind tunnel test for directional efficient vertical axis wind turbine,no-load rotate speed is 300 r/min when wind speed is 5m/s.With-load rotate speed is 90 r/min when wind speed is 5.2m/s.
