Abstract<br />

Wind energy is the fastest growing source of energy and is getting<br />

worldwide attention due to the technological advances for harnessing the<br />

wind power and its competitive cost of production compared to other<br />

traditional means. Wind turbines are used in many places of the world. In<br />

most of the cases, it is fitted with a generator to convert mechanical energy<br />

to electrical energy and batteries to store electrical energy. But lots of<br />

energy losses will occur due to conversions and also, more money is<br />

required. In order to avoid these problems, the wind power utilization is<br />

restricted to pumping of water in to a tank. But many times the tank will be<br />

full and energy will be wasted. Hence in this project, it is directly used to do<br />

mechanical work for polishing materials to get good surface finish.<br />

1. INTRODUCTION<br />

Mainly there are two types of wind turbines.<br />

i. Horizontal Axis Wind Turbine (HAWT) and<br />

ii. Vertical axis Wind turbine (VAWT)<br />

1.1 Horizontal Axis Wind Turbine:<br />

Horizontal-axis wind turbines (HAWT) have the main rotor shaft and electrical generator at<br />

the top of a tower, and must be pointed into the wind. Most have a gearbox, which turns the<br />

slow rotation of the blades into a quicker rotation that is more suitable to drive an electrical<br />

generator. Since a tower produces turbulence behind it, the turbine is usually pointed<br />

upwind of the tower. Turbine blades are made stiff to prevent the blades from being pushed<br />

into the tower by high winds. Additionally, the blades are placed a considerable distance in<br />

front of the tower and are sometimes tilted up a small amount. Downwind machines have<br />
