WIND POWER
WIND
An estimated 1% to 3% of energy from
the Sun that hits the earth is converted
into wind energy.
The principle of wind is simple. The poles
recieve less energy than the equater does
from the sun. Also land heats up and cools
down more quickly than the seas. This
difference between the seas and the land
causes a global atmospheric convection
system.
GENERAL INFORMATION ABOUT
WIND TURBINES
Producing electricity from wind power has started
100 years ago.
The petroleum crisis in the 1970s has started the
development in wind turbines.
Modern wind turbines are generally two or three
bladed.
Their rotor diameter is generally 10 to 30 meters.
Their lifetime is at least 20 years.
They are controlled by a computer system.
An economic power plant has a capacity of about
10-30MW.
Wind speed increases by height so many tirbunes
are around 30-50 meters tall.
THE PRINCIPLE OF A WIND
TURBINE
The wind power can be gained by
making it blow past the blades that
will cause the rotor to twist. The
amount of power transferred is
directly proportional to the density of
the air, the area swept out by the
rotor, and the cube of the wind
speed. It can be found out by the
following equation:
TYPES OF WIND TURBINES
1.Onshore
Onshore wind turbines are placed in hilly and
mountainous places and are at least three
kilometers away from the nearest shore.
2.Near-shore
Near-shore wind turbines are installed within
three kilometers from the nearest shore or on
water within ten kilometers from land.
3.Offshore
Offshore wind turbines’ developement zones are
at least ten kilometers away from land.
TYPES OF WIND TURBINES
4.Vertical-axis
The main difference of vertical-axis wind
turbine is that the blades are installed
vertically while other turbins’ blades are
installed horizontally.
5.Airborne
Airborne wind turbines are tethered aeral
turbines filled with helium.
WIND POWER IN TURKEY
Turkey is a eligable country at the point of
producing electricity from wind power
because,
1.It is located in the temperate zone.
2.Surrounding dinamic pressure contrasts
are very effective.
3.There are coasts on the northern,
western and southern sides of the land.
4.The position and the outstrech of the
mountains.
Wind potentials 50 meters above sea level at five different topographic situation.
Inland areas Bare lands Coasts Open seas Hills and slopes

Primary locations for
wind power in Turkey
•Where transportation is
always possible and easy,
•Near the transformer
stations.
•On top of bare hills.
•Balıkesir Şamlı
•İzmir Çeşme
•Gelibolu Fındıklı
Secondary locations for
wind power
•Where transportation is always possible and easy
•Near transformer stations
•Coasts and fields
•Bandırma – Manyas – Karabiga
•Çeşme
Tertiary locations for wind power
Where transportation is
always possible,
Near transformer stations,
Bare lands( fields).
Fourth degree locations for
wind power
• Where transportation is not always possible, so new road(s) must be
built for maintenance of the turbines.
• not near transformation stations.
• Moderately planted hills.
İzmir – Çeşme- Kocadağ
Çanakkale – Ayvacık – Bozcaada – Gelibolu
Fifth degree locations for wind power
• Where transportation is not always possible, so new road(s) must be built
for maintenance of the turbines.
•Not near transformation stations.
•Forested hills.
Balıkesir – Balya – Yenice
Çanakkale – Çan – Biga

THE USE OF BIG-ROTOR
TURBINES
Electricity produced by
big rotors get transferred
to centeral electricity
network. Some of the
electricity that’s needed
in industrial fields is
provided from wind
power.
THE USE OF SMALL-ROTOR
TURBINES
Small turbines are generally
used in the fields where
centeral electricity network
has problems providing
energy or there is no way to
reach it. Settlements at
country sides, farm houses,
telecommunication and
radio transmitters, forestry
observation towers, military
facilities, railroad
signalization, fish farms,
green houses, mines, ships
are some examples of these
fields. The electricity
produced by these turbines
get stored in generators.
ADVANTAGES AND
DISADVANTAGES OF WIND
ADVANTAGES:
POWER
1.It’s unlimited.
2.They don’t cover up a lot of space and the spaces
between are usable.
3.When the turbines become unusable they can be
disposed easily and the area left behind can be
reused.
4.Wind industry is developing speedily around the
world.
DISADVANTAGES:
1.They produce unwanted sounds.
2.They can block electromagnetic waves.
