3. Introduction
Wind turbine is a devices that convert kinetics
energy from the wind into electric power.
Wind energy is created when the atmosphere
is heated unevenly by the sun, some patches
of air become warmer than others. These warm
patches of air rise, other air rushes in to
replaces them thus, wind blows.
It works opposite of fan turbine blade spin
from the wind and make energy instead of
using energy to make wind.
The first windmill used to produced electric
energy was created in 1888 by Charles F. Brush.
The wind power programmed in India was started
during 1983-84 with the efforts of the ministry of
non-conventional energy sources.
5. Function Of Component
Foundation :- Foundation give support to wind turbine. It consists of solid
concrete assembly
Tower :- it connected rotor and foundation and raise rotor so that it can
operate at required wind. Made up of steel having tube like
structure
Rotor & rotor Blades :- it is rotating part which converts wind energy to
rotation. It made up of glass-fibre, carbon-fibre,
reinforced plastics.
Nacelle:- contains the key components of the wind turbine including the gearbox
yaw system and electric generator.
Low speed shaft :- connects the rotor hub to the gearbox.
High speed shaft :- drive the electric generator by rotating at high speed
6. Function of component
Gearbox :- the gear box converts the rotor motion of lower rpm into the
higher rpm.
Coupling :- coupling is done between the main shaft and the transmission.
Generator :- generates electricity from rotation of shaft.
Controller :- it is a self operating system used in control system. It may be
sensor ( mechanical, electrical) decision element ( relays,
microprocessor) and actuators ( hydraulic ,electric ).
Yaw mechanism :- turn the nacelle with the rotor into the wind using motors.
Anemometer and wind vane :- measure the speed and the direction of the
wind while sending signals to the controller to start
or stop the turbine.
8. Types of wind turbine
1. Horizontal axis type
A horizontal axis machine has its blades rotating on an axis parallel to
the ground
Single blade horizontal wind
turbine
Double blade horizontal wind
turbine
Three blade horizontal wind
turbine
Lower blade weight and less
cost. More vibration &
unconventional look.
Similar to single blade HAWT.
Have stability problem.
Balance of gyroscopic forces
increases gearbox costs.
9. Types of wind turbine
2. Vertical axis type
vertical axis wind turbine have the main rotor shaft arranged vertically.
VAWTs runs in any wind direction.
Good efficiency drag type turbine
Produce large torque and cyclic stress on used incase of high reliability in many things
The tower require some external power such as ventilation and anemometers.
Source to start turning. Self starting
less efficient

12. Site selection
Njj ooiiu9u99iiii
High annual average wind speed
Altitude of proposed site
Terrain and aerodynamic
Easy of transportation
Nearness to user/ centre
Local ecology & nature of ground
Off shore and sea coast (2400 kwh/m2 per year)
Mountains (1600 kwh/m2 per year)
Planes ( 750 kwh/m2 per year)
Consideration during site selection
Best site for wind turbine
13. Wind farms
A wind farm or wind park is a group of wind turbines in the same location used to produce
energy
Offshore wind farms onshore wind farms
1 wind farm located right off the coast 1. less wind power available than offshore.
or in sea using floating platform. 2. Less installation cost.
2 more wind power but more cost. 3. Usually near to user but create noise
and visual problem.
London array, united kingdom (630 MW) Jaisalmer wind park, Rajasthan ( 1064 MW )
14. Location of wind farm
worldwide there are now over two hundred thousand wind turbines operating, with a total nameplate
Capacity of 318105 MW.
Top 10 country by nameplate wind power capacity wind energy installation in state across India
15. Safety system
Emergency stop:- if a situation arise which call for the wind turbine to be
stopped immediately, it is used and wind turbine stop ion
few second by fathering the blade directly into the wind.
Computer and sensors:- the wind turbine is controlled by a computer data
from sensors which monitors the most important
gauging instrument and compare the result , if found
error wind turbine stopped.
Lightning rods:- The wind turbine system is protected from lighting by these
rod going from the tip of the blade to the ground.
Temporary rope system:- this system provide temporary fall protection during
construction , maintenance and inspection of wind
turbine
16. Advantage
Good for environment as it uses renewable sources of energy as wind.
Wind is freely available in nature.
Can be setup in remote areas where electricity through transmission wire
cannot be reached.
Clean source of energy as it does not produce any green houses gases or any
other pollution.
Once setup is completed the cost of generation electricity become less.
Can be combined with solar electricity to give reliable supply of electricity.
17. Disadvantage
Site specific i.e. suited to particular region.
Create a lot of noise disturbances.
Cause visual impact.
High initial cost.
Large requirement of land for wind farming.
Threat to wild life as it kills bird.
