3. INTRODUCTION
 A "wind farm" is a group of wind turbines in the same location used for
production of electric power.
 Individual turbines are interconnected with a medium voltage power
collection system.
 At a substation, this medium-voltage electrical current is increased in
voltage with a transformer for connection to the high voltage transmission
system.
 A large wind farm may consist of a few dozen to several hundred
individual wind turbines, and cover an extended area of hundreds of
square miles (square kilometres), but the land between the turbines may
be used for agricultural or other purposes.

4. TYPES OF WIND FARMS
 On-Shore
 Off-Shore
 Near-Shore
 Air borne

5. Off-shoreOn-shore

6. Near shore Air borne

7. ON-SHORE WIND FARM
It Converts kinetic energy-mechanical energy-
electrical energy.
Wind turbines operate on a simple principle i.e
The energy in the wind turns three propeller-like
blades around a rotor. The rotor is connected to the
main shaft, which spins a generator to create
electricity.
 Wind turbines are mounted on a tower to capture
the most energy. At 30 meters or more above
ground, they can take advantage of faster and less
turbulent wind.
 Early turbines were small by today's standards,
with capacities of 20-30 kW each. Since then, they
have increased greatly in size delivering up to 7
MW.

8. OFF-SHORE WIND FARM
 Off shore wind farms is also called as
floating wind parks.
 Floating wind parks are wind farms that
site several floating wind turbines closely
together to take advantage of common
infrastructure such as power
transmission facilities.
 A floating wind turbine is an
offshore wind turbine mounted on
a floating structure that allows
the turbine to generate electricity.

9. TYPES OF WIND TURBINES
Most common industrial design
today.
HAWT have the main rotor shaft
and generator at the top of a tower
and must be pointed into the wind.
HAWT, where wind velocities are
high.
Able to increase height of tower to
harness higher wind velocities at
higher altitudes.Horizontal Axis Wind Turbine Design
 Horizontal Axis Wind Turbine

10. Vertical Axis Wind Turbine Design
VAWT have the main rotor shaft
arranged vertically .The
generator and gear box placed
near the ground.
Utilizes wind flow in all
directions (360°).
Constructed on buildings to
avoid ground level turbulence.

12. COMPARISON TO OTHER ENERGY
SOURCES
 Environmentally friendly.
 Large resource supply.
 Cheap operating costs.
 Wind – 55.80/ MWh
Coal – 53.10/ MWh Natural
Gas – 52.50/ MWh

13. Safe & Pollution free.
Inexhaustible.
Inexpensive after installation.
It is cheaper to put more coal into an
existing power station than to build a new
wind farm.

Factors Affecting Wind Farms

16. CONCLUSION
Nowadays, wind energy is developing rapidly all around the
world. There are many options of wind power generation and
collection system configuration.
Wind energy has matured to a level of development where it is
ready to become a generally accepted utility generation
technology ,a brief discussion of this development is
presented.
