INTRODUCTION

Wind energy, as a clean and

renewable energy, is now

being widely developed to

reduce the production of

carbon dioxide from fossil

fuels and mitigate the energy

crisis. The urgent needs for

wind energy motivate larger

generators with lower cost,

lower weight, and higher

reliability and new

technologies to make it a

frontrunner.

HISTORY OF WIND USE

Man’s harnessing of the wind goes back thousands of years

Sail Boats

Wind Mills

Wind Turbines

HOW DOES IT WORK???

Wind turbines convert wind energy to electricity for distribution. Conventional horizontal axis turbines can be divided into three components:

The rotor component

The generator component

The structural support component

TYPES OF WIND TURBINES

Wind turbines can rotate

about either a horizontal

or a vertical axis.

♣ Horizontal-axis wind

turbines (HAWT)

♣ Vertical-axis wind

turbines (VAWTs)

WIND TURBINE GENERATORS

WTG’s are of following

types:

DC Generators

AC Synchronous

Generators

They may be of:

1. Fixed Speed Type

2. Variable Speed Type

SCOPE OF WIND POWER IN INDIA

CONCLUSION

The installed power in wind energy has grown rapidly in many years. Today more than 45000 MW are installed globally with recently an annual market of 8000 MW. The expectations for the future are also very positive as many countries have progressive plans.

Of course there are problems associated with wind farms
