IT IS A SIMPLEST PRESENTATION

2. Wind energy
By: AZHARUDDIN

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
