Wind Power Generation
A propeller rotates by wind and power is generated by accelerating the rotation of a propeller as fast as power can be generated by an accelerator.
There are a rotational wing that convert wind power to rotating energy, a converter that is formed with a motor, gear and generator, a tower that supports the converter and motor, a controller and a connector for additional devices inside a system.

When winds pass through a rotational wing that looks like a propeller, air flows around the upper part of the wing gets faster. Due to this, a low pressure occurs around the upper part of the wing and the difference in atmospheric pressure on the surface of the rotational wing generates aerodynamic lift forces.
Because the rotational wing is designed to move only horizontally just like the rotational axle, lift forces makes the rotational wing rotate around the rotational axle. An important issue to consider when designing the rotational wing of a wind turbine is to have the ratio of lift force and resistance.
This ratio helps decide the length of a rotational wing to gain turbine energy that is suitable for diverse wind speeds.

 

Wind power is one of the most significant renewable energy sources. Safe and inexhaustible wind power can play an important role in developing sustainable energy, and supply power to the various types of electric devices. Wind power does not cause air pollution and leave hazardous wastes.
Since it is a rotational system and generates AC power unlike photovoltaic systems or fuel cells, additional equipment such as an inverter is not required and excellent efficiency can be achieved.
