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.

6
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.

THE WIND POWER DISTRIBUTION FOR EACH REGION IN
TURKEY
10
Primary locations for wind power in Turkey

• Where transportation is always possible and easy,
• Near the transformer stations.
• On top of bare hills.

• Balikesir Samli
• Izmir Çesme
• Gelibolu Findikli

11
Secondary locations for wind power

• Where transportation is always possible and easy
• Near transformer stations
• Coasts and fields

• Bandirma Manyas Karabiga
• Çesme

12
Tertiary locations for wind power
Where transportation is always possible, Near
transformer stations, Bare lands( fields).
13
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.

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.

THE USE OF BIG-ROTOR TURBINES

• Electricity produced by big rotors get
  transferred to centeral electricity network. Some
  of the electricity thats needed in industrial
  fields is provided from wind power.

16
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 POWER

• ADVANTAGES
• 1.Its unlimited.
• 2.They dont 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.
