This document describes the design and components of a wind turbine generator. It contains sections on the basic components of a wind turbine - the DC motor, blades, and tower. It explains that a DC motor is used to convert the kinetic energy of the wind into mechanical energy. Common wind turbine designs use either two or three blades attached to a hub. The tower raises the rotor and blades to heights with higher wind speeds. Diagrams and specifications are provided for a sample 3-foot wind turbine design, including dimensions, a gearbox ratio, and intended applications for power generation.

Hybrid power generation by and solar –windUday Wankar
With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind
energy. This kind of system is usually called windsolar
hybrid power generation system significantly
In this presentation a brief introduction is given on parts of wind turbine, classification of wind turbines, importance of wind turbines, current status like installed capacity (annual and cumulative) . Then there is a explanation on theory behind the design of wind turbine blades i.e, AERODYNAMICS OF WIND TURBINES which includes explanation about shape of an aerofoil, its different parameters, lift force, drag force, different equations about lift drag force, NACA profiles, Blade Element Momentum Theory, etc.

Renewable energy is generally electricity supplied from sources, such as wind power, solar power,
geothermal energy, hydro power and various forms of biomass. The popularity of renewable energy
has experienced a significant upsurge in recent times due to the exhaustion of conventional power
generation methods and increasing realization of its adverse effects on the environment. Wind energy
has been harnessed for centuries but it has only emerged as a major part of our energy solution quite
recently and this report focus on utilizing wind energy by using vertical axis wind turbine.

Design of PVC Bladed Horizontal Axis Wind Turbine for Low Wind Speed RegionIJERA Editor
The Project is aimed at designing a wind turbine that can be able to build by Laypersons, using readily available material which is feasible & affordable to provide much needed electricity. Since most of the high wind power density regions in the zone of high wind speed are already being tapped by large scale wind turbine and so it required creating a large scope for the development of low wind speed turbines. Our study focuses primarily on designing the blade for tapping power in the regions of low wind power density. The aerodynamic profiles of wind turbine blades have major influence on aerodynamic efficiency of wind turbine. This can be achieved by comparing the effectiveness of a crude blade fashioned from a different Size, Material & standard of PVC drainage pipe which are easily available in market. It can be evaluated by performing experimental analysis, data collection & its evaluation on different type & size of PVC Pipe & preparing an analytical tool for best Design.
Wind power or wind energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping. Wind power is a sustainable and renewable energy, and has a much smaller impact on the environment compared to burning fossil fuels.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. What is wind turbine/wind mill
Wind turbine is a device that converts kinetic energy into
mechanical energy
If the mechanical energy is used to produce electricity, the
device may be called a wind turbine
If the mechanical energy is used to drive machinery, such as
for grinding grain the device is called a
wind mill.
4. Why Did we take this project
of wind turbine?
IT’S VERY CHEAP.
WIND POWER CONSUMES NO FUEL. SO IT IS VERY RELIABLE.
MORE EFFICIENT.
SUITABLE FOR KARACHI CLIMATE.
COMPARED TO THE ENVIRONMENTAL IMPACT OF
TRADITIONAL ENERGY SOURCES, THE ENVIRONMENTAL
IMPACT OF WIND POWER IS RELATIVELY MINOR IN TERMS OF
POLLUTION.
WIND TURBINES CAN CARRY ON GENERATING ELECTRICITY
FOR 20-25 YEARS. OVER THEIR LIFETIME THEY WILL BE
RUNNING CONTINUOUSLY FOR AS MUCH AS 120,000 HOURS
6. 1. DC Motor
A DC MOTOR IS A MACHINE WHICH CONVERTS ELECTRICAL
ENERGY INTO MECHANICAL ENERGY.
7. Construction of DC motor
DC MOTOR CONSISTS OF THE FOUR IMPORTANT PARTS.
ARMATURE: A RECTANGULAR COIL WHICH IS MADE OF
INSULATED COPPER WIRE WHICH IS WOUND ON THE SOFT IRON
CORE THIS IS ARMATURE.
FIELD WINDING: THE FIELD WINDINGS ARE ATTACHED TO
INSIDE OF THE YOKE AND TO FORM TWO POLES FITTING
CLOSELY TO THE ARMATURE.
COMMUTATER AND BRUSHES: COMMOTATOR IS USED TO
REVERSE THE DIRECTION OF CURRENT. PRESS SLIGHTLY AGAINST
THE TWO SPLIT RINGS AND THE SPLIT RING ROTATE BETWEEN THE
BRUSHES. THE CARBON BRUSHES CONNECTED TO THE DC
SUPPLY.
8. Internal structure:
THE YOKE (OR CASING): IT COVERS THE WHOLE MACHINE
AND PROVIDES THE MECHANICAL SUPPORT TO THE POLES
9. WORKING PRINCIPLE OF DC MOTOR
when A current coil conductor is placed inside of the
magnet field .when the current is passed through the
conductor a field is produced around it. And the
direction of this magnetic field can be determined by
the right hand rule .because of the current flows
through the segments of the loop is in different
direction it means that that are opposite to each
other as shown in the figure .The segment on one side
pushes the upward while the segment on the other
side pushes the down word. it mean that both sides of
the armature experience the force which is in equal in
magnitude but in opposite in direction and its known
as couples forces these combined forces create the
twisting action or torque.
10. The direction of Forces
HERE THE DIRECTION OF COUPLE FORCES CAN BE FOUND WITH
HELP OF FLAMING LEFT HAND RULE .WHICH STATED THAT IF WE
POINT OUT THE INDEX FINGER IN THE DIRECTION OF MAGNETIC
FIELD AND THE MIDDLE FINGER IS IN THE DIRECTION OF CURRENT
THE THUMB WILL SHOWS THE DIRECTION OF MAGNETIC FORCE. AS
SHOWN IN THE FIGURE BELOW.
11. Why we use Dc motor not
AC motor?
Due to below reasons we use DC motor:
High starting torque.
Speed control over a wide range, both below and
above normal speed
Quick starting, stopping
12. Blades:
ON THE BASIS OF BLADES THERE ARE TWO TYPES OF
WIND TURBINES.
VERTICAL AXIS WIND TURBINE (VAWT)
HORIZONTAL AXIS WIND TURBINE (HAWT)
13. (1) VAWT
IN VAWT GENERATOR IS MOUNTED AT THE BASE OF
THE TOWER AND THE BLADES ARE WRAPPED
AROUND THE SHAFT VERTICALY.
14. (2)HAWT
In HAWT, blades are on the top, spinning in the air,
wrapped horizontality on the shaft and are most
commonly seen.
15. Calculation of Wind Power
•Power in the wind
– Effect of swept area, A
– Effect of wind speed, V
– Effect of air density, R
Swept Area: A = πR2 Area
of the circle swept by the
rotor (m2).
Power in the Wind = ½ρAV3
17. Number of Blades – One
Rotor must move more
rapidly to capture same
amount of wind
Blades easier to install
because entire rotor can
be assembled on ground
Captures 10% less energy
than two blade design
18. Number of Blades - Two
Advantages &
disadvantages similar to one
blade
Need teetering hub and or
shock absorbers
Capture 5% less energy than
three blade designs
19. Number of Blades - Three
Balance of gyroscopic
forces
Slower rotation
120 Angel apart from each
other
10% more Energy than Two
blades rotor
22. Tip-Speed Ratio
Tip-speed ratio is the ratio of the
speed of the rotating blade tip
to the speed of the free stream
wind.
There is an optimum angle of
attack which creates the
highest lift to drag ratio.
Because angle of attack is
dependant on wind speed,
there is an optimum tip-speed
ratio

23. TOWER
The Structure or Tower consists of
Rotor
Blades
Hub
Low-speed shaft
Bearings
Gearbox
Generator
Main frame
Electrical connections
Cooling systems
Assembly and installation

27. Length of Tower
and Wind Speed
Speed of Wind increases exponentially as the
height of tower increases. From this graph, one
can see that at low heights, the wind speed
increases significantly at first, but at higher heights
the rate of increase is much less.
28. Energy In the Wind
Ew = (Ws
3 *(1.2252/2)*As) /1000
Ew= Energy in the Wind
Ws= Wind Speed (mph)
As= Swept Area of Blades
30. APPLICATIONS:
IT CAN BE USED TO PROVIDE ELECTRICITY TO
SECURITY AND CCTV CAMERAS
ALSO TO POWER STREETLIGHTS AND TRAFFIC
MANAGEMENT SYSTEMS
IT IS USED TO DRIVE SAILBOATS
IT IS USED TO LIGHTING UP THE SMALL VILLAGES
AND URBAN AREAS HOME
IT IS USED IN INDUSTRIES DUE TO ITS LOW COSTS
BY USING IT WE CAN AVOID CONVERTING POWER
FROM AC TO DC OR DC TO AC. EVERY TIME THE
POWER IS CONVERTED, YOU WILL LOSE 25% TO 30%
OF THE POWER
