This document discusses wind energy and the parts of a wind turbine. It begins by describing a wind energy company that generates electricity from wind turbines it manufactures and maintains. There are typically two types of wind turbine foundations and towers made of steel and concrete. The main parts of a wind turbine are the blades, rotor, generator, gearbox, and controller. Blades capture the wind and spin the rotor, which turns the gearbox and generator to produce electricity. The controller monitors wind speed and orientation to operate the turbine safely and efficiently.

3.  The Origen 0f our story begin in 1994
 Our wind farms today straddle seven high potential
states
 This company not only generate electricity from wind
turbine but also it manufacture the turbine and
maintenance also
 This company is ISO 9001:2008 certified For
manufacturing , installation , and service

4. In terms of business result the turnover of this company
is increasing through the year
Our Success Power:
Concept to commissioning to life time care solution
Superior product offering

5. WHAT IS WIND
Wind is the flow of gases on a large scale on the surface of
the earth
and in general it consist of the bulk movement of air
CAUSES OF WIND
It is caused by different in the atmospheric pressure.
When a difference in atmospheric pressure exist the air
moves from high o low pressure

6. THERE ARE MAINLY 13 PART

7. FOUNDATION
There are mainly two type of foundation
i. Shallow flat disk: 40ft diameter and 3ft thick
ii. Deeper cylinder: 15ft diameter and16ft deep
And it is made of concrete reinforced with steel bars

8. Typically two type of tower exist
1. Floating tower
2. Land base tower
It is made of steel
And the height of tower is 212ft & 262ft
The weight of tower is 71 & 220tone

9. Other parts

11. Blades:
Lifts and rotates when wind is blown over them, causing the rotor
to spin. Most turbines have either two or three blades.

12. Rotor:
Blades and hub together form the rotor.

13. Pitch:
Turns (or pitches) blades out of the wind to control the rotor
speed, and to keep the rotor from turning in winds that are too

14. Brake:
Stops the rotor mechanically, electrically, or hydraulically, in

15. Low-speed shaft:
Turns the low-speed shaft at about 30-60 rpm.

16. Gear box:
Connects the low-speed shaft to the high-speed shaft and
increases the rotational speeds from about 30-60 rotations per
minute (rpm), to about 1,000-1,800 rpm; this is the rotational speed
required by most generators to produce electricity. The gear box
is a costly (and heavy) part of the wind turbine and engineers are
exploring "direct-drive" generators that operate at lower rotational
speeds and don't need gear boxes.

17. High-speed shaft:
Drives the generator.

18. Generator:
Produces 50-cycle AC electricity.
Fixed speed
generators:
don't need to be
corrected, but aren't
as able to take
advantage of
fluctuations in wind
speed.
Variable speed
generators:
produce electricity
at a varying
frequency, which
must be corrected
to 60 (50 in Egypt)
cycles per
second(Hz) before it
is fed onto the grid.

19. Wind vane:
Measures wind direction and communicates with the yaw drive to
orient the turbine properly with respect to the wind.

20. Anemometer:
Measures the wind speed and transmits wind speed data to the

21. Controller:
Starts up the machine at wind speeds of about 8 to 16 miles per
hour (mph)(5-10)km/h and shuts off the machine at about 55
mph(34 km/h). Turbines do not operate at wind speeds above

22. Yaw drive:
Orients upwind turbines to keep them facing the wind when the
direction changes. Downwind turbines don't require a yaw drive
because the wind manually blows the rotor away from it.

23. How Does a Wind Turbine
Generate Electricity?
Blades and rotor: Converts the wind power (kinetic
energy)to a rotational mechanical
power.
Gear box: Wind turbines rotate typically between
30
rpm and 60 rpm. Generators typically
rotates at 1,000 to 1,800 rpm. Most wind
turbines require a step-up gear-box for
efficient generator operation (electricity
production).
Generator: Converts the rotational mechanical power
to electrical power.
If a specially developed multi-pole ring (direct-drive)
generator is used, the gearbox is no longer required
