4.4 Types of Wind Generators
Various types of generators that are used for wind power generation are induction generators and
synchronous generators. In this section a brief review of different types of generators including their
advantages and disadvantages are presented.
Generators suitable for Constant speed turbines:
 Squirrel Cage Induction Generator (SCIG) Generators suitable for variable speed turbines:
 Doubly Fed Induction Generator (DFIG)
 Permanent Magnet synchronous Generator (PMSG).
4.4.1 Induction Generators
The induction machine is a well–established technology, as its application as a wind generator, using
a gear drive to a generator with a low number of poles. In general, because of its small air–gap, the

Therefore, they may increase the maintenance cost. Another solution to improve the power factor is
to insert a power converter in series with the armature circuit. In this way, full control is obtained
over the induction generator performance, but at the cost of a converter capable of handling the full
power of the generator.
4.4.1.1 Squirrel Cage Induction Generator
A squirrel cage induction generator is an asynchronous machine, with a squirrel cage rotor and
stator, which is directly connected to the grid. The wind turbine rotor will be directly coupled to the
generator through a gearbox, which matches the rotational speed of blades with that of the generator.
Essentially this is a constant speed wind turbine because the power converted from the wind is
limited by designing the turbine rotor in such a way that its efficiency decreases under high wind
speeds. Induction generator is the most common generator in wind energy systems because of its
simplicity, ruggedness, low maintenance and low cost. The main drawback in induction generator is
its consumption of reactive power for producing the real power. The VAR compensation can be done
with the help of fixed capacitance connected near the Induction generator. The fixed capacitance
method of VAR compensation is generally done when the torque applied to the induction generator
is constant. In practice, most wind farms have fixed capacitor banks installed to fulfill

Is the electric car a viable sustainable replacement for an ICE car?
The electric car is not, by any means, a new concept. The electric car was first introduced in the 19th
century, but as oil was more plentiful and much cheaper than electricity, the internal combustion
engine came to the forefront of the transportation sector.1 Now, as oil reserves around the globe
have reached the lowest since 1973 and gas prices the world over are soaring,1 the world has turned
back to the electric car.1 The electric car was endorsed by the United States Government in 2009 as
"a promising alternative to petroleum in the transportation sector", and 2.1 billion dollars has been

Together these chemicals, along with a number of others, form smog, the dirty brown cloud often
seen hanging over large Canadian cities such as Toronto or Vancouver, or towns with a large amount
of pollution, such as Fort McMurray.5
For the purpose of this paper, CO2 emissions will be focused on, as CO2 is the most abundant
greenhouse gas after water vapour.5 The CO2 emissions of the electrical generation methods will be
compared to the emissions of the internal combustion engine. Due to the emissions created by an
electrical power plant, the power used to run the electric vehicle must be produced in a sustainable
manner if an electric car is to be truly sustainable in comparison to the internal combustion engine
car. This leads to an analysis of the different types of power generation –coal, oil, natural gas,
geothermal, nuclear fission, wind, and hydro. Each are analysed to determine which gives off the

Voltage And Frequency Control Of Wind Hydro Hybrid System...
Abstract–This paper presents a voltage and frequency control of wind–hydro hybrid system in
isolated locations in which one squirrel cage induction generator (SCIG) driven by a variable speed
wind turbine and another SCIG driven by a constant power hydro turbine feeding three phase four
wire local loads. The system mainly uses a rectifier and a pulse width modulation controlled
insulated–gate–bipolar–transistor–based voltage–source converters (VSCs) with a battery energy
storage system at their dc link. The main objectives of the rectifier is to convert the ac power
generated by the wind system to dc and the control algorithm for the VSC is the control of the
magnitude and the frequency of the load voltage. This system has the capability of bidirectional
active– and reactive–power flow, by which it controls the magnitude and the frequency of the load
voltage. Here pitch angle control is used to achieve maximum power tracking(MPT).In this paper
wind turbine, hydro turbine, MPT controller, and a voltage and frequency controller are modeled
and simulated in MATLAB using Simulink and Sim Power System set toolboxes, and different
aspects of the proposed system are studied for various types of loads, and under varying wind–speed
conditions. The performance of the proposed system is presented to demonstrate its capability of
MPT, voltage and frequency control (VFC), harmonic elimination, and load balancing.

Implementing Sustainability And Adaptation For Sustainability
Incorporating sustainability and adaptation
Introduction:
Mayukwayukwa is a refugee settlement in Zambia that is home to over 11,000 refugees (Engineers
Without Border, 2016). The town was established in 1966 and relies on diesel generators to power
there boring devices (1). However, these generators only run for a few hours a day leaving the
community to hand pump for the remainder of their water supply. The design that is proposed in the
design section of the report will function all day and through the night to combat this issue. This
report will also demonstrate how climate change is an issue related to sustainability. It will
demonstrate how these issues are incorporated into the design of the project for the people of
Mayukwayukwa. ... Show more content on Helpwriting.net ...
However, the generators only run for a few hours a day due to insufficient funds for diesel. During
the time the generators are not running the staff have to walk to the closest borehole to collect the
water for use (Engineers Without Border, 2016). This is where the design could be integrated into
the community. Implementing solar, and wind boring systems running simultaneously to bore the
water in to tank storage facilities. This solution runs without labour and without the need for fossil
fuels. This would mean, a constant supply of water for the health clinic. This allows the nurses to

This paper deals with generating electricity by utilizing the flow of air on the vehicle while cruising
on a highway. The micro wind turbines are coupled to micro generators placed above the trunk at
the rear end of the car. Two turbines have been tested at various speeds of the vehicle ranging from
50 – 80 mph on the freeway. When hooked up to an electrical load consisting of 4 LED bulbs
connected in parallel, consistent output of 4V and 800mA was achieved using the two turbines
connected in parallel. Keywords– Micro Wind Turbines; Vehicle; Electricity generation. 1.
Introduction When any vehicle is moving on the road it experiences resistance due to the wind. As
the vehicle moves forward, air flows along the surface of the vehicle in the opposite direction. This
kinetic energy in the air can be utilized to propel the turbine, which in turn rotates the generator
shaft connected to it. This test can be performed on any vehicle. Since an automobile was available
at our disposal, we choose to test the setup of micro wind turbines on it. There were few studies
which dealt with this concept in several other ways and none of them have actually tested out their
designs. Our primary aim was to prove that electricity can be generated using micro–wind turbines
on any moving vehicle. Hence, the aerodynamic performance of the car was not given much
consideration during the experiment. CFD analysis

Abstract
Wind power, as a kind of renewable energy, is widely used for electric power generation. Being
clean and easily acquired, wind power generation has a bright future. The conversion between wind
energy and electric power can be divided into two parts. The kinetic wind energy is converted into
mechanical energy by the wind turbine first. Then the mechanical power is converted into electrical
power by a generator. The more efficient the conversion is, the less wind power the generator loses.
Therefore, study on the efficiency of power conversion becomes an important subject. In this
literature review, Maximum Power Point Tracking (MPPT) in Permanent Magnet Synchronous
Generator (PMSG) under Power Signal Feedback Control algorithm will be mainly discussed.
Introduction
Wind power not only is clean and renewable but also has a large storage. The storage of wind power
is ten times more than the storage of hydro energy which could be exploited and used. It is regarded
as an alternative to burning fossil fuel, is widely distributed produces no greenhouse gas emissions
during operation and uses little land [1]. For islands, grassland, pastoral area, mountain and
highland, the water and fuel are always in a shortage. This situation makes the wind power the most
suitable energy source for these areas. Therefore, more and more countries have put high importance
to the use of wind power. The

Tesla's Father moved to Gospic and Tesla became even more distressed because of his love of his
old village. His father had done more training to increase his memory of the bible; but moreover
Tesla had found something intriguing to him a shelf of books in the back of the church that Tesla
enjoyed reading to pass the time. Tesla also developed strange likes, dislikes and habits. At the age
of 12 Tesla found a Serbian translation of a book called Abifi. "Abifi in the beginning of the Novel
is unruly at the beginning but ends dying as a hero for his prince and country." Inspired by this Tesla
used his will to begin to control his visions, and use them for more productive purposes that will

during school became ill. So ill that doctors and physicians gave up on Tesla (they didn't whether or
not it was related to his visions or that he had visions), but recuperated slowly while reading books
that the local library had sent in volumes. After he completed his studies at Karlovac, Tesla went
home to Gospic. When he returned there was an epidemic of cholera. Tesla fell ill and fought the
multitude of sicknesses and diseases for nine months. He was bed ridden and fell into "dropsy

How Large Scale Generators Work? Let 's Start With Their...
Have you ever wonder how Large Scale Generators work? Let's start with their history, the first
Large Scale Generators was invented around August, 1895, the way it worked was with water being
diverted through a pair of high–speed turbines that coupled to two 5,000 horsepower generators. But
before even that happened it all started from discoveries and inventions made years before in
regards to the generation and transportation of electricity. Michael Faraday; an English scientist help
discover the diamagnetism, electrolysis and electromagnetic induction. Faraday was humble, since
he was a kid, he took an interest in energy and forced. Around 1832–1832, Faraday had an idea that
an electromotive force is generated in an electrical conductor which in fact encircles a magnetic
flux, and was later called after him "Faraday's Law".
A lot of inventions happened during that time, for instance; the first electrical generator capable of
delivering enough power to industry which was called "Dynamo"; it consisted in rotating coils of
wire and magnetic fields to convert mechanical rotation into a direct electric current. At the very
beginning Generators were built at the places where the power was more in demand, especially
since there was no energy companies that operated the power grid like we do now a days. Later on
around the 1870's, other many inventors started using Faraday's principle to generate electricity
mechanically. There after two kinds of generators were created, one was

Electric Power, Motors and Generators Surround Us Every Day
Introduction
Our world is powered by electricity; it surrounds us in every turn and every corner, powering our
streetlights, our TVs, our hospitals, our homes, and our communities. Electricity is a form of energy
that results from charged particles. There are many energy sources that can be converted into
electricity, and that's why it is suited for powering our society. We can generate electricity from
burning fuels, energy of falling water, solar energy, and basically anything that has energy.
Electricity is also easy to distribute, using transmission lines connecting the energy power station to
homes, schools and so on. Atoms consist of electric charge, so electric charge is everywhere and the
electric charge has an electric field. An electric field can only be created by a positive charge and
destroyed by a negative charge(Brightstorm, 2010). According to Bob emery, owner of senior
physics website, to generate electric power it requires motion between a magnetic field and a
conductor. Attraction of a magnet is limited to certain boundaries this is called the magnetic field of
a magnet (Makemegenius, 2013).
An electric current in a magnetic field will experience a force, (HyperPhysics, 2014) due to the
interaction between the charged particles in the electric current and the magnet, this force is called
the motor effect. To find the direction of magnetic field you use the right–hand rule, pointing the
thumb in the direction of the current and curling your fingers in

energy from the car engine through a thermoelectric generator using peltier plates has been
proposed. This electricity generated through the thermoelectric generator from waste heat of the
engine could be used to charge the car batteries or operate any electrical device within or outside the
car. Also, in other application of this thermoelectric generator that is, Electricity generation from
glaciers / ice is another alternative for electricity generation through other non –renewable resources

Global warming is the most concern to the environmental issues and the limited availability of
conventional fossil fuels lead to rapid research and development for more sustainable and alternative
electrical sources in recent years. Wind energy, as one of the most prominent renewable energy
sources, is gaining increasing significance throughout the world. Distributed generation (DG) based
on renewable energy has become a development trend for electric power industry in 21st century.
But DG is affected by natural conditions being not able to output power continuously and steadily,
so when large scale wind turbine generators incorporated into the grid will bring impact on electric
power system stability.
In order to ensure stable operation of electric power system, a super capacitor energy storage system

(PCC). Matlab/Simulink software is used for modelling

Electricity Generation
Electricity generation is the process of creating electricity from other forms of energy.
The fundamental principles of electricity generation were discovered during the 1820s and early
1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is
generated by the movement of a loop of wire, or disc of copper between the poles of a magnet.[1]
For electric utilities, it is the first process in the delivery of electricity to consumers. The other
processes, electricity transmission, distribution, and electrical power storage and recovery using
pumped storage methods are normally carried out by the electrical power industry.

Sources include: * Steam – Water is boiled by: * Nuclear fission, * The burning of fossil fuels (coal,
natural gas, or petroleum). In hot gas (gas turbine), turbines are driven directly by gases produced by
the combustion of natural gas or oil. Combined cycle gas turbine plants are driven by both steam
and natural gas. They generate power by burning natural gas in a gas turbine and use residual heat to
generate additional electricity from steam. These plants offer efficiencies of up to 60%. *

The Deregulation Of Generation Facilities Essay
INTRODUCTION . Centralization of generation facilities give way to smaller, more distributed
generation partially due to loss of traditional economies of scale.Penetration of distributed
generation across U.S has not yet reached significant levels. However that situation is changing
rapidly, requires attention to issues related to high penetration of distributed generation within the
distribution system.Distributed generation encompasses wide range of prime mover technologies,
such as IC engines, gas turbines, microturbines, photovoltaic, F.C(fuel cell), wind–power. Most
emerging technologies such as micro–turbines, photovoltaic, F.C's, gas internal combustion engines
with permanent magnet generator require an inverter to interface with electrical distribution system,
These emerging technologies have lower emissions, potential to have lower cost negating traditional
economies of scale.All applications include power support at substations, deferral of T&D upgrades,
onsite generating. Indiscriminant application of individual distributed generators can cause as many
problems as it may solve. better way to realize emerging potential of distributed generation is to take
system approach which views generation, associated loads as subsystem or "microgrid". This
approach allows for local control of distributed generation thereby reducing or eliminating need for
central dispatch. During disturbances, generation, corresponding loads can separate from
distribution system to isolate

The Power Of Magnetism And Electricity Since Ancient Times
Introduction:
Mankind has been aware of the presence of magnetism and electricity since ancient times.
Prehistoric man observed instances of lightning and static electricity, as well even creating a
primitive version of the compass. Magnetism wasn't officially discovered until the late 16th Century,
and it would be even longer until scientists learn to wield electricity for demonstrations in the 18th
Century. Now, three–hundred years later, we are combining these two forces to enhance
transportation across the globe. From underground subway systems, all electric cars and even hover
cars, electromagnetism has revolutionized the way we get around.
Once the concepts of electricity and magnetism were grasped, it did not take long for automobile
manufacturers to begin to use electricity and magnetism to improve their products. Before the starter
motor was implemented, engines had to be manually primed by the use of a hand–crank. Not only
was this a bothersome inconvenience to automobile owners, but it was dangerous as well. Any
number of injuries could be sustained from a back–firing engine. As engines became larger and
more powerful, it also became more physically demanding to start them, making it almost
impossible for those with any sort of handicap to operate without assistance.
History:
In 1896, in East Peckham, England, H.J. Dowsing installed the first electric starter on an Arnold,
and the idea soon spread to the United States. Cadillac released self–starting models in

Decentralized power production can bring immunity to largescale electrical grid failures. As wind
turbines can be adapted to this use, increasing amounts of wind power will be utilized as a means to

These examples suggest that wind power will be used in ways that correspond to each needed
capacity and purpose. In the article "Wind Energy: An Untapped Resource," the Wind Energy
Association estimates the potential amount of wind power generation capacity in the U.S.A. at
10,777 billion kW/h, which is three times the electricity generated in the U.S.A. today. However, it
also predicts that we are unlikely ever to use even half of that potential. In fact, in 2000, the U.S.A.
was using less than 1% of that potential! This is because wind power is not always the superior
method, and there are some problems still to be solved.
In the article "Nuclear Now," Schwarts and Keiss point out some problems with wind power
generation. First the "Whish, Whish" sound of the turning fan might bother the people living nearby.
A relatively large area of land is needed for huge wind turbines. Also birds can be killed by the

The Physics Of Mechanical Materials
dges The wedges that hold the rotor winding in the slots are sometimes also complex in design, but
always highly stresses. The wedges must hold the copper winding and its insulation systems in place
at high rotational speeds and allow cooling gas to pass through them. This one reason why at the
wedges there are higher stresses. The wedges generally have cooling vents machined into them,
which reduces their effective strength. High cooling gas temperatures can also affect wedge strength
if the temperatures begin to affect the creep life of the material. The wedges are generally made of
lightweight materials, such as aluminum or brass, in the winding slots. This area does not generally
carry the useful magnetic lux, so the wedges do not need to be made of magnetic material.
AMORTISSEUR WINDING Most modern rotors employ a damper or amortisseur or damping
winding to dampen torsional oscillations and provide a path for induced currents to flow. The
amortisseur winding is essentially a separate winding installed under the rotor wedges and
retaining–rings that is connected similar to the squirrel–cage of an induction motor. It produces an
opposing torque when currents flow in it, and this helps dampen torsional oscillations and add to the
stability of the rotor during system stress events. In some instances, where full–length aluminum
wedges are used in the rotor, these may serve additionally as part of the damper winding. Also some
designs use the

Current Technology on Winding Linear Generators Essay
Current Technology on Winding Linear Generators Abstract
This paper is an overview of the materials and winding technology that is currently used on today's
linear generators. It contains information on the types of wire used as well as the epoxy used to hold
the coil windings in place. Furthermore, it contains information on the possible orientations that the
coils can have with respect to the permanent magnets.
Introduction
Linear generators/motors have been around since the early 1900's with one of the first written
references being in regard to Birkeland's Cannon, then described as a tubular motor but is more
accurately described as a reluctance motor. 1

In the following examples the coil wires are shown to be perpendicular to the motion of the
permanent magnet. The flux in the coils changes direction as the permanent magnet passes through
the coils in the Sandia Alternator Design. This change in flux with respect to time as well as
direction induces current in the coils in both directions.5
Another method for winding the coils involves the use of several separate coils connected by two
bus wires. 6 Current is induced in the individual coils as the permanent magnet and then routed to
the output via the two bus wires.6
Epoxy Resins for Windings
The windings on the linear generator are almost always coated with some sort of epoxy similar to.
This accomplishes two things: the first is to secure the windings in place and the second is to
provide for additional insulation. The windings need to be secured in order to prevent the wires from
separating due to the forces that each wire exerts on the other wires that surround it. This force is
due to the current that passes through it. The following is an explanation (found on Rare Earth
Magnets.com) of the forces created by electricity flowing through a wire:
"The magnetic field force produced by a current–carrying wire can be greatly increased by shaping
the wire into a coil instead of a straight line. If wound in a coil shape,

Types of DC Motors and DC Generators MOTORS – convert electrical energy to mechanical energy
Motors and generators are the most frequent used electrical machines. ❖ Generators action can take
place when and only when, there is a relative motion between conducting wires and magnetic lines
of force. ❖ Electric motor is in operation when it is supplied with electrical energy and develops
torque, that is, a tendency to produce rotation. ❖ In DC generator, the armature winding is
mechanically rotated through the stationary magnetic fields created by the electromagnets or

This motor does not have good speed regulation, but it is popular for high torque load. 3. Compound
motor – a machine that is excited by a combination of shunt field connected in shunt with the
armature and series field connected in series with the armature. ❖ The shunt field gives this motor
good speed regulation, as a shunt motor has, but the series field gives it the ability to handle
overloads well. The current through the series field and armature increases when an overload
decreases the speed of the armature. This increases the motor's power, and the overload does not
reduce the speed as drastically as it would with a shunt motor. The compound motor can be
controlled for over speed and under speed in the same way that the shunt motor can. 4. Permanent
Magnet Motor – has permanent magnet fields and an armature that is similar to any DC motors
armature (manufactured in fractional to the low integral horsepower sizes). INTERPOLES OF DC
MOTOR Nearly all shunt and compound motors of ½ hp or more have commutating poles or
interpoles located between the main poles. This interpoles have one winding of heavy wire and are
connected in series with the armature. The purpose of this interpole is to prevent sparking. The
polarity of the interpoles depends on the polarity of the main poles aand the direction of the motor's
rotation. ➢ Rule for Interpole

your final project. Gears (or pulleys) are usually used to transmit the power from the motor (input)
to the output. A pair of gears forms a simple gear train. As engineers, you will need to understand
how motors and generators work in order to pick appropriate ones to use in different applications or
to know how your design will behave when hooked up to a particular motor/generator. In your final
project for this course, you will use a generator (i.e. for wind power generation) and

Models Predictive Control For A Finite Time Horizon
4. Model predictive control
MPC is a general term for computer control algorithms [10] that uses an outright process model to
predict future response of the plant.
An optimized input is determined by solving an open–loop optimal control problem over a finite
time horizon. The number of samples one looks forward is called the prediction horizon Np. While,
number of samples that the optimal input is computed for is called the control horizon Nu. The
complexity of the problem can be decreased by selecting a shorter control horizon than prediction
horizon. From the calculated input signal only the first element is applied to the system.
This can allows solving online the optimized control problem, where prediction error action and
control input are minimized through a future horizon, possibility of subject to constraints on the
manipulated inputs, outputs and states. Then, the optimization returns an optimal control sequence
as input and the first input only from the sequence is used as input to the system. By the next sample
interval, the total optimization approach repeated and the horizon shifted. This approach is used to
allow indemnity for modeling error and future disturbance. Basic structure of model predictive
control is shown in Fig. 2. Fig. 2 Basic structure of model predictive control
In an MPC–algorithm there are four important elements:

The model is in most MPC–formulations today given on discrete time state space form:

The Benefits of harnessing Wave Energy
There are many benefits to using waves as a source to produce electricity (Plummer et al., 2009):
Sea waves offer the highest energy density among other renewable energy sources
There are limited negative impacts on the environment; wave energy harnessing devices have the
lowest potential impact
Waves travel long distances with little energy loss
Wave power devices can generate power 90% of the time whereas other sources of renewable
energy, such as wind and solar power, can only generate power 20 – 30% of the time
3. Final Concept: Point absorber coupled with a piston–crank concept
The point absorber was selected as the device used to harness energy from the wave, due to the
benefits the device yields.

The piston–crank concept would be a one solution of converting the heaving motion, absorbed by
the buoy from the sea, and converting it to mechanical energy. The mechanical energy would then
be converted to electrical energy via a

Government 's Plan Of Action
Government's Plan of Action to Secure Electricity Supply Energy, especially electricity, is important
for economic development. Electricity plays an important role toward economic growth as it is
essential in using pieces of equipment that are used in the manufacturing processes of various
products (ESMAP 8). The increasing population and expanding economy contribute to the increase
in the demand for electricity. Especially in summer, there are many people would like to stay at
home with the air conditioning on rather than having activities outdoors. Currently, China is the
major consumer of electricity because of the huge population and industrial demand. However, the
electricity produced in this country is not enough to supply its needs (Global Energy). The economic
progress could not pursue if there is insufficient amount of energy that any country could use.
Electricity shortage can happen if the available supply in an area cannot meet its demand. If this
situation is prolonged, the price of the electricity might increase. Different countries experience
electricity shortages because of the increasing demand for electricity. As the executive body of a
nation, the government has implemented other strategies to deal with the problem, such as energy–
saving methods and restriction of electricity used. These two have their own advantages and
disadvantages, but both have been effective in resolving the electricity shortages. Restricting
electricity use is an effective

The Request Of Force Is Heightened Within The Realm Of Power
I. INTRODUCTION
The request of force is heightened in the realm of power. This development of interest triggers a
need of more power generation. DG utilizes smaller sized generators than does the ordinary central
station plant. Distributed generators are little scale generators found near purchasers; regularly
Distributed Generators are of 1 kW to 100 MW [1].
Meaning of DG [2].
Distributed generation in straightforward term can be characterized as a small scale generation. It is
an active power generating unit that is connected at distribution level.
IEEE characterizes the generation of power by offices adequately littler than central plants, for the
most part, 10 MW or less, to permit interconnection at about any point in the power system, as
Distributed Resources.
Electric Power Research Institute (EPRI) characterizes distributed generation as generation from a
couple of kilowatts up to 50 MW.
International Energy Agency (IEA) characterizes DG as "Power generation equipment and system
utilized for the most part at distribution levels and where the power is fundamentally utilized locally
on site".
The International Council on Large Electricity Systems (CIGRE) characterizes DG as generation
that is not midway arranged, halfway dispatched at present, typically connected to the distribution
network, and smaller than 50–100 MW.
These generators are appropriated all through the power system nearer to the load. The DG
penetration in the grid postures new difficulties

Electricity Generation
Electricity generation is the process of creating electricity from other forms of energy. The
fundamental principles of electricity generation were discovered during the 1820s and early 1830s
by the British scientist Michael Faraday. His basic method is still used today: electricity is generated
by the movement of a loop of wire, or disc of copper between the poles of a magnet.[1] For electric
utilities, it is the first process in the delivery of electricity to consumers. The other processes, electric
power transmission, electricity distribution, and electrical power storage and recovery using pumped
storage methods are normally carried out by the electrical power industry. Electricity is most often

Many of the heat engines just mentioned are turbines. Other types of turbines can be driven by wind
or falling water. Sources include: Steam – Water is boiled by: Nuclear fission, The burning of fossil
fuels (coal, natural gas, or petroleum). In hot gas (gas turbine), turbines are driven directly by gases
produced by the combustion of natural gas or oil. Combined cycle gas turbine plants are driven by
both steam and natural gas. They generate power by burning natural gas in a gas turbine and use
residual heat to generate additional electricity from steam. These plants offer efficiencies of up to
60%. Renewables. The steam generated by: Biomass The sun as the heat source: solar parabolic
troughs and solar power towers concentrate sunlight to heat a heat transfer fluid, which is then used
to produce steam. Geothermal power. Either steam under pressure emerges from the ground and
drives a turbine or hot water evaporates a low boiling liquid to create vapour to drive a turbine.
Other renewable sources: Water (hydroelectric) – Turbine blades are acted upon by flowing water,

Electrical Power Of Ac Generators
Introduction
Power lines are cables that carry electrical power (Google definitions 2015). This electrical power is
generated by Eskom, an electrical energy supplier company, and carried via the power lines to many
areas around the country.
To be able to produce so much current to the whole of country, AC generators are normally used
(Horner, Davies & Toerien 2012). A generator is a device that turns mechanical energy into
electrical energy (Olivier 2015). A generator is usually either AC( alternating–current) or DC( direct
current). An AC basic principle is that the coil rotates mechanically in a uniform magnetic field; this
magnetic field then induces an electrical field. Due to a part of the coil always being connected to
the same slip ring and brush it can be said that the brush is sometimes negative and sometimes
positive (Olivier 2015).
Although it's easier and cheaper to use AC generators one must take into consideration the health
hazard that accompanies the use of power lines that transports this alternating current.
Investigation Question
Is there a health hazard that accompanies the use if power lines in residential areas?
Hypothesis
The use of power lines in residential areas can be seen as a health hazard.

Different Traditional Windmills And Its Exterior...
ABSTRACT
Wind energy is found in abundant & is free. Moreover, this renewable resource is pollution & noise
free. However, harvesting this energy to produce electricity & to be able to use it directly in our
homes or public places is restricted due to many reasons. Bigger size, less cost–efficient, lower
overall efficiency, non–uniformity in wind etc are some of the reasons that such systems are not
being installed in residential or urban areas. Our project will focus on studying variety of such
stand–alone wind–power systems & proposing such systems which are suitable to our environment.
Design of our project will be different from the existing traditional windmills & its exterior
architectural beauty will be enhanced.

Noisy, Monstrous, Nauseous, giant, unpleasant, bird scaring are some of the basic properties that
blink in our mind when we think about wind turbines. If we specifically talk about horizontal axis
wind turbine(HAWT) then most turbines are not efficient when it is installed closed to the ground
where there is not much wind. Also, the tall towers and long blades are very expensive and difficult
to transport and install. Another disadvantage of HAWT is that it is difficult to perform repairing
operations to HAWT because the gear box , generator and the rotor are all placed at the top of the
tower. So to overcome this problems there is another option of Vertical Axis Wind

The disadvantages of wind generators are that the strength of the wind isn't constant and it varies
from zero to storm force. This suggests that wind turbines don't manufacture constant quantity of
electricity all the time. Many of us feel the rural area ought to be left untouched, while not these
massive structures being engineered.

Who was Michael Faraday?
Michael Faraday was a British physicist and chemist, best known for his discoveries of
electromagnetic induction, the magneto–optical effect electro–magnetic rotations, the magneto–
optical effect, field theory, diamagnetism and of the laws of electrolysis. His biggest breakthrough in
electricity was his invention of the electric motor. Many famed historians regard him as the most
prestigious and ideal experimentalist within the history of science.
Michael Faraday was born in Newington Butts, London on 22 Sept 1791. He was the third child
born in an extremely poor family, where his father was a blacksmith. As a result to his poor family
background, Faraday couldn't get pleasure from a large college and had to mostly educate himself.
Michael Faraday built two devices to produce what he called electromagnetic rotation: that is a
continuous circular motion from the circular magnetic force around a wire.

Abstract
A hydroelectric generator is a machine that uses mechanical energy to generate electricity, the
hydroelectricity comes from a large volumes of falling water to create the mechanical energy. I will
be constructing my own hydroelectric generator in order to show it is possible to create electricity
using large volumes of water, enough power to light a light bulb.
Background
Making Electricity and Hydroelectric Generators
Electricity is the flow of electrons through a metal wire, or through a conductor. Electrons are tiny
particles found in atoms, and is also one of the building blocks of all matter. Electrons carry tiny
negative charges, when they move through a conductor they produce a little invisible magnetic
force. The strength depends on how in motion the electrons are. Pushing the electrons a little closer
and tighter can cause a stronger field. When electrons produce a magnet force, you can use a magnet
to make the electrons mover which is how an hydroelectric generator works.
A hydroelectric generator is a machine that uses mechanical energy to generate electricity, the
hydroelectricity comes from a large volumes of falling water to create the mechanical energy. For
more than 100 years the simplest way to produce the volumes of falling water needed to make
electricity was to use dams to create electricity. But sometimes dams

The Energy Of Wind Energy
ABSTRACT:–
The main purpose of the wind energy is to create energy source which is pollution free and come
with a reasonable price. The wind energy used in wind turbines are increasing their demand and
becoming popular in the green energy world. Since the rebirth or rapid growth of wind energy took
place from early 1980. The growth of the industry has been more than expectations. As all the good
things the wind energy poses certain negative impacts of having high maintainer cost. Repair and
data collection should be monitored regularly of the turbine to get the idea of placing a new wind
energy plant or to maintain the old one. This paper explains the modeling of Wind Energy
Conversion Systems and their technologies which is used for the generation of wind power and
control strategies of the conversion system. INTRODUCTION:–
Energy is considered as one of the most important factor to run the world. Most of the energy or
large part of it are generated by the fossil fuel, which are being used from a long time which are
causing a major problem in environmental and the damage done is not reversible. As the fossil fuel
are damaging and are also limited in quantity available, so the need of alternate energy was needed.
Wind energy is considered as low effects on the environment and growing faster day by day which
is considered as quarter in last few decades. The process of capturing is considered as easy as and
less damaging than the other energy sources. Wind power is taken

alarmingly less than 7% of our toll energy usage comes from Alternative energy resources. This
leads to the edge of a dangerous presuppose as our current resources continue to dwindle and our
future grows darker each day. It is estimated that there is less than 200 years of oil left in the
reserves we currently have and with the population and the demand for oil increasing each year it
could be here faster then we know it. As we continue to pour pollutants back into our skies, waters
and lands each year our planet feels the effect each day.

Solar power is the most abundant most renewable resource that we have and it is free. The process
starts when the sun shines on Solar PV panels that have been installed on your roof. Photovoltaic
refers to the scientific process by which solar energy is converted into electricity. There are a
number of silicon cells within each PV panel. These react with photons, or units of light, from the
sun to produce direct current or electricity. DC electricity then travels to an inverter, which converts
this energy to electricity known as alternating current or AC that can be used in your home or office.
AC electricity then travels to the distribution network in your home powering your domestic or
office appliances. When your solar panels produce more electricity than your home or office is
using, the extra electricity gets fed back into the national grid. Yet, there are many processes the PV
cell actually goes through to produce power of electricity. The top and bottom layer of the PV cells
are protective glass layers with conducting coding's. Electricity in the form of electrons flows in and
out of these conducting coding's while electrical production process happens in the middle layer of
the PV cell. At the molecular level, a photon strikes a dye molecule absorbed on the surface of the
TiO2 causing an excited state, which releases an electron into the TiO2 that exists through the
conductive layer. The
