Wind power is generated when the earth orbits the sun daily, it receives light and heat.

Across the earth there are areas with different temperatures, so this heat transfers from one area to another area. Due to heat differences wind is created. In warmer regions of the earth, the air is hot and is therefore at a high pressure, compared with the air in colder regions, where there will be a low pressure. Wind is the movement of the air from high pressure to low pressure. From this the idea of generating power from wind came to action. When compared with conventional sources, wind energy offers great potential to generate electricity without the causing any pollution problems.

Mechanical energy in wind has been used for thousands of years for numerous applications like in milling, pumping water and other mechanical power applications. But the use of wind energy as an electrical supply with free pollution what makes it attractive and takes more interest and used on a significant scale. Wind Energy Conversion System (WECS) includes either an induction type or a synchronous generator within its structure. The permanent magnet synchronous generator is considered as best choice for wind turbines due to its simplicity of its generating mechanism and good power density.
