| 摘要 |
<p>The present invention relates to a wind turbine system using solar chimney draft comprising one large diameter centrally-mounted outward radial-flow or mixedflow wind-turbine. The chimney has thin curved fins designed for smooth flow guidance at entry and tangential exit to increase suction effect due to swirling flow inside the chimney space. This gives higher power due to bigger rotor diameter, thereby increasing wheel torque even at lower wind speeds. An electricity producing single generator is centrally mounted through suitable gear ratio to generate electricity at higher frequency for gridding action.</p> |
