摘要

Wind power is of increasing interest in society due to its prospects as an environment friendly source of renewable energy. Wind turbines are generally classified into two types: horizontal axis and vertical axis. The promising advantages of vertical axis wind turbines such as omni-directional, ability to take turbulent and gusty winds, and low installation and maintenance costs etc makes it suitable for small capacity domestic applications. This paper briefs about the design and development of a 1000W vertical axis wind turbine of Darrieus type. This design uses three airfoils mounted on a hub that ensues rotational symmetry. The wind power extracted by the airfoil is transmitted to the generator located at the ground through a long shaft. The analytical design shows higher safety margins (greater than 5) in the wide working ranges of wind speed 5-15 m/s.
