WIND TURBINE
INTRODUCTION:
Windmills are incredible creations that have its importance in our history. Early pioneers utilized windmills for pumping water out of the ground and
provide the water for their cattle's over a century. Throughout the years, diverse outlines and varieties were made to make the windmill run more
effectively. In spite of the fact that there have been many plans made, a large portion of the windmill parts still remained unaltered.
Now–a–days the handling of "Electricity" has been increased rapidly. Due to this the "Fossil Fuels" are getting extinguished day–to–day. So we need to
choose for an alternate source of energy that is Renewable Source. Among the Renewable Sources "Wind Energy" is one of them.... Show more content

Rotors are placed in the blades and in the hub. The main function of rotor is to convert wind energy into rotation. "Lift" principle is used in the rotor
blades. The two forces over pressure which is produced by wind at the bottom of the wind blade and vacuum at the top o f the wind blade makes the
rotor to rotate.
YAW DRIVE: The main function of yaw drive is to move rotor according to the direction of the wind, otherwise a yaw error is produced which results
in less utilization of wind.
YAW MOTOR: Its function is to power the yaw drive.
CONTROLLER: Controller is a sub–system which acts as a watch–dog in the sense it controls various parts of the turbine. It automatically stops
working of the turbine if any faults occur and information is passed to operator's computer.
TOWER: Tower height is mandatory in producing more electricity. Wind capturing capability of the turbine increases as the tower height increases. As

The integration process would be slow until there was more emphasis on its use in society. It will be true with wind turbines as well; more
transmission lines will be needed to make them more appealing for the general public and businesses.
Another problem with building wind turbines is that you are placed on a waiting list in order to be able to build one and "waiting lists now fall
somewhere in the vicinity of a year–and–a–half to two years". (10) The wait may not be too long considering the benefits that they can provide, but
then building one becomes an even more difficult issue because there is "the necessity of one of only six cranes in the country that are capable of
hoisting the turbine's pieces into place". (11) The construction also takes months and even years, if you are planning a wind farm. After all this work,
some people would question whether or not it was worth it. The British Wind Energy Association states that "it is cheaper to save electricity than to
generate it, by whatever method", (12) but since people don't take actions to reduce their electricity use, another method has to be put into place. "On
average, MN residents use 7 blocks of electricity/month. This premium of 1Вў/kWh compares to the price of under 10Вў/kWh for non–wind power.
Each year, every block of wind power purchased will have the same environmental benefit of planting ВЅ acre of trees or not driving a car 2400

How Have Wind Turbines Changed Over The Years
Wind turbines have altered the way that we get our energy. Wind turbines are used to harness wind power and turn into electricity. They are comprised
of usually 2 or 3 blades that are connected to a shaft that was attached to a generator which then turns into electricity. Although we now generally use it
to produce electricity, wind energy was originally used in the form of windmills to do chores and housework. Because of the rapid increase in the use
of wind turbines, it has added jobs and changed the way we get energy.
Wind turbines over the years
Wind turbines have evolved over the years to develop into what they are today. People have been using technology for years. For example, it was used
for transportation sailboats as early

Renewable Energy Resources : Wind Turbines Vs Solar Panels...
RENEWABLE ENERGY RESOURCES
– WIND TURBINES VS SOLAR PANELS–
HOW THEY WORK
Wind turbines:
A wind turbine turns wind into energy. As wind blows towards the blades of the turbine, the rotors spin around, capturing kinetic energy from the wind.
The rotor blades are able to rotate around the hub (located at the front, middle of the turbine) allowing them to meet the wind at the best possible angle.
Inside the nacelle (the main body of the turbine), the gearbox is able to convert the low–speed turning of the drive shaft into high–speed rotations that
are fast enough to drive the generator proficiently. The generator then takes the kinetic energy from the spinning shaft and turns it into the electrical
energy. With the help of anemometers that provide the measurements of wind direction and speed, the rotors and nacelle can be rotated by a yaw motor
allowing the blades to face directly towards the oncoming wind, capturing the maximum amount of energy possible. The electrical current produced by
the generator then flows through a cable running through the centre of the turbine tower. From there, a step–up transformer converts the electrical
energy to a voltage about 50 times higher. The energy can then be transmitted efficiently to buildings and homes nearby or to the power grid.
Solar Panels:
A solar panel turns the sun's light into energy. Solar panels are made up of many small solar cells. Every one of these cells needs light from the sun to
allow the electrons to move. Each

The constructions of the turbines alone are creating an effect on these mammals because of the frequency of noise that is emitted into the water. These
frequencies disrupt mammal communication, location and location of other species around them.
One other environmental factor regarding wind turbines, especially the wind farms, is that "erecting and maintaining wind turbines can also
necessitate clearing land: ridgeline installations often require a fair amount of deforestation, and then there's the associated clearing for access roads,
maintenance facilities, and the like". (7) Although we are trying to help the environment by creating a safer and cleaner source of energy, the actions
of clearing our forests, and whatever ecosystem that lived in that forest, in order to save the environment appears to be an oxymoron. "But there are
also now a great many turbines situated on farmland, where the fields around their bases are still actively farmed". (8)
The long term effects of this issue could be devastating if precautions are not taken. Small rodents are known to find shelter at the base of the large
wind turbines, luring different bird species to wind farms causing a higher death rate for the birds. The wind farms are also unfortunately located in the

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

Wind Power : Wind Turbines
The Answer Is Blowing in the Wind
Wind energy is a term used to describe the process by which the wind is used to generate electricity or mechanical power. This alternative energy
source is not a new technology. Wind mills, similar to wind turbines, have been in use since 2000 B.C. and were first developed in China and Persia.
Now with the increasing demand for renewable power, wind turbines or wind generators are beginning to be seen scattered over the countryside. Wind
power is believed to be a practical, renewable source of green energy. Wind turbines, like large aircraft propeller blades, turn in the moving air and

Wind energy can be generated in most geographical areas, anywhere in the world where the wind blows consistently and with a strong enough force to
make wind energy generation efficient. The stronger the wind the more power produced. Some of the best locations for wind farms are large
agricultural areas and coastlines. This causes conflicts with other prime concerns, such as agriculture, urban development, or waterfront views.
Wind energy may seem to be only a clean and non–controversial renewable energy source, but wind energy turbines do have some environmental
concerns. The noise factor is one of those concerns, the sound may be disguised by the sound of the wind, but there is a definite noise from the
turbines. Analysts and engineers have worked to improve turbines so the noise is reduced. Other environmental concerns are the aesthetic issues they
cause to the land, and how the turbines possibly interfere with radar or telecommunications. Also the flying rotors take part in bird and bat deaths. Even
though they have these concerns they still have little impact on the environment compared to fossil fuels. These problems have also been either
resolved or greatly reduced through technological development. According to the wind energy foundation, "In 2013, roughly 168 million
megawatt–hours generated by wind energy avoided 95.6 million metric tons of carbon dioxide (CO2) – the equivalent of reducing power–sector CO2

Wind Turbines Essay
Introduction:
Wind turbines capture the energy of wind and transform it into kinetic energy that is then converted to electricity. Turbines are available in a range of
sizes and designs and can either be free–standing, mounted on a building or integrated into a building structure (Pennycook, 2008).
System types:
There are basically two sorts of wind turbines: horizontal–axis design and vertical–axis design. Horizontal–axis wind turbines are the most common
type used and can have various sizes. This type of turbine has a horizontal rotor shaft and generator usually located at the top of a tower. The
propeller–type blades are used to capture wind thus are oriented into the wind, for instance for small turbines a wind vane is used, or if ... Show more
As a matter of fact in a direct–connected system, the wind turbine output is connected directly to the load. A turbine direct–connected control unit is
used to provide the interface between the turbine and the load.
As for battery system this charges the wind turbine after capturing energy in the battery bank, via a control unit. A controller is needed to ensure that
the batteries are not over or under charged and can direct electrical power to another load for example space and/or water heating when the batteries
are fully charged.
The advantages and disadvantages of wind turbines
Wind turbines are recognized as one of the fasted growing renewable energy and very sustainable for the environment but it also has its own advantages
and disadvantages. They are as follow:
Advantages
Firstly, it has a clean energy which means that obtaining energy form the wind produces zero emissions into the atmosphere. Less space is needed,
wind turbines usually take up very less space than what is necessary for a single power station, the rest of the surrounding land can be used for other
purposes for instance agriculture. Wind turbine is a renewable energy, therefore unlike fossil fuels, the wind will not run out, and can provide the planet
with a limitless source of free power. In addition, wind turbines generate energy in remote locations such as mountainous or countryside

Designing horizontal–axis wind turbine (HAWT) blades to achieve satisfactory levels of performance starts with knowledge of the aerodynamic
forces acting on the blades. In this paper, HAWT blade design is studied from the aspect of aerodynamic view and the basic principles of the
aerodynamic behaviours of HAWTs are investigated. Firstly, blade design procedure for an optimum rotor according to CFD analysis as well as
analytical calculations.Then designed blade shape is modified such that modified blade will be lightly loaded regarding the highly loaded of the
designed blade and power prediction of modified blade is analysed. When the designed blade shape is modified, it is seen that the power extracted
from the wind is reduced about 10% and the length of modified blade is increased about 5% for the same required power.

The more blades there are on a wind turbine, the higher will be the torque and the slower the rotational speed. But turbines used for generating
electricity need to operate at high speeds, and actually don't need much torque. So, the fewer the number of blades, the better suited the system is for
producing power.
A one–bladed wind turbine is the most efficient turbine design. This is because the turbine blade sweeps 360 degrees before encountering its wake.
However, only having one blade causes many problems structurally and dynamically, so it is not very feasible.
A two–bladed turbine is the next most efficient because each blade sweeps 180 degrees before reaching the wake of the other blade, but you get
something called yaw chatter when the turbine rotates to face the wind. The yaw chatter cause noise, vibration, and stress on the tower.
A three–bladed wind turbine is the most efficient turbine design without having any dynamic issues. This is why pretty much all large wind turbines
these days are three

I can still remember that I've made a windmill by a paper in my childhood. I hold my windmill running on the lawn. Currently, wind power has
become the world 's fastest growing renewable power source. The earliest use of wind to produce energy is when the Egyptians are said to have
used it to propel their sailboats through the water. At 1300's, the windmill appeared in Europe and was used in the to drain fields. After hundreds of
years, people have utilized the wind to do works and used across North America pumping water by the end of 1800's. It was called steel blades at that

The generator turns rotational energy into electricity. At its essence, generating electricity from the wind is all about transferring energy from one
medium to another.
The main components of a windmill consist of blades, rotor and generator etc. The blades are the most important feature of the wind turbine. It looks
like sails, normally have two or three blades, they are aerodynamically shapes to make the most of the energy in the wind, turning a shaft which is
connected to a generator and turn into wind power. When the wind forces the blades to move, it has transferred some of its energy to the rotor which
is the technical term for the entire hub. It is also known as a propeller. The rotor usually consists of two or more wooden, fiberglass or metal which
rotates about an axis at a rate determined by the wind speed and the shape of the blades. In addition, rotor can turn a generator which transforms the
mechanical energy into electricity. There is an electric motor orientates the nacelle so that, rotor is positioned facing into the wind. In terms of
generator, that is converts the motion of wind turbine in to electricity. A simple generator consists of magnets and a conductor. The conductor is
typically a coiled wire, they are rotated in a magnetic field to produce electrical voltage. The shaft connects to permanent magnets which surround by
coils of wire. In the electrical process, when the conductor that has magnets rotating to the other, there is an electric

What Are The Advantages And Disadvantages Of Wind Turbines?
Wind Turbines
Wind turbines are a renewable energy they work by the wind turning the blade, the blade then turns a shaft inside the nacelle(the box at the top of the
turbine), the shaft then goes into a gear box which increases the rotation speed, the generator then converts the rotational energy into electrical energy,
the transformer then converts the electricity from around 700 volts to the right voltage for distribution which is usually 33,000 volts after all of these
procedures, the national grid then transmits the powers around the country.
Some things a typical wind turbine consist of, the tower which is a cylinder made of steel painted light grey and from 25 to 75 meters tall, wind
turbines also have rotor blades which are always on a wind turbine and have in–between 1 to 3 made of fibre glass–reinforced or wood–epoxy and
theses are usually in–between 30 and 80 meters in diameter, the longer the blades the greater the energy output, the rotor blades typically rotate at 10 to
30 revolutions per minute at constant speed but some vary as to increase or decrease the output speed. Wind turbines also contain a yaw mechanism
which turns the turbine to face the wind.

The Power Of Wind Turbines
Introduction
Today society shares enthusiasm about the expansion and increased production of alternative energy to meet the global energy needs, rather than
relying on the limited supply of fossil fuels. It is estimated, by the end of this century, the fossil fuels that sustain civilisation will be depleted. So to
prepare for the new age of energy production, development of renewable energy sources such as wind power is very important.
Wind & Wind Turbines
Wind is formed from the heating and cooling of the atmosphere, which causes air and air layers to rise, fall and move over each other. This movement
results in wind currents. The kinetic energy of wind can be transformed into electrical energy through the use of wind turbines.
There are two main types of wind turbines, horizontal and vertical axis. Vertical axis wind turbines (VAWT) have blades which are connected to the
vertical shaft. The horizontal axis wind turbines (HAWT) however all the main components on top of a tall tower. Since horizontal axis wind turbines
are the most common used, the report will focus on this design.
The Gearbox
As the wind passes over the blades it creates lift which causes the rotor to turn. The blades turn a low–speed shaft inside the nacelle. The gearbox
connects the low speed shaft to the high speed shaft and increases the rotational speeds from 30 – 60 rotation per minute (rpm) to around 1000 –1800
rpm. This is about the rotational speed required by most generators to produce

Effects Of Conventional Ground Based Wind Turbines
Tethered airfoil HAWP devices have 3 main components: 1.) the airfoil or lifting surface, 2.) the tether, and 3.) the anchor point or base station
[1]. One of the benefits of these devices over conventional ground based wind turbines is that the material footprint of each device is significantly
less than their ground based counterparts for the same amount of power generated [6]. These devices do require slightly different materials than
HAWTs for example, however they are not significantly more complex, which should allow them to penetrate the market in a similar fashion to
how ground based turbines did and became widespread. The first main component of these HAWP devices, the airfoil or lifting surface, could be
made of a variety of materials. If the device uses a parasail as in [1] [4] [6] [7], then it is likely to be made of conventional parasail materials,
namely nylon. If instead of a parasail, an airfoil is used, then such an airfoil will likely be made out of similar materials to airplane wings. Airplane
wings and thus airfoils, can be made out of a variety of different materials, ranging from wood and cloth used on old WWI planes, to aircraft grade
aluminum used in modern airliners, to composite materials found in today's gliders. Any of these materials could be potentially viable for the airfoil,
as different materials are suited to different properties of the airfoil [1]. If the airfoil also has onboard power generation in the form of propellers that

Wind Turbine: A Study to Harness a Energy Source Essay
Introduction
Following the recent developments in renewable energy sources, wind turbines have been one of the primary devices focussed on. Basically, wind
turbines are devices that convert the kinetic energy from the wind into electrical power for human usage. "Wind farms" are created in very windy
places to harness this energy.
It is however impossible to harness the entire power potential from the wind. Only 59% of the total kinetic energy of the wind flowing in the turbine can
be harnessed. Efficiency greatly depends on the maintenance of the wind turbine and its components.

It is usually best to calibrate with a calibration block made from the same material as the real component. Althought this results in higher costs but it
gives certainly most reliable results. Open cracks and tight cracks can be separated from each other with eddy current technique.
However a crack which goes through grain boundary is clearly more difficult to estimate. Figure 1 shows eddy current signals from three cracks that
were found with dye penetrant testing. a) 3 surface breaking cracks on a turbine bladeb) Eddy current signals from cracks.
Fig 1: Eddy current signals from the three cracks shown in the blade .
Measuring the width of a layer is simple with eddy current technique, if there are no strong changes in permeability. In addition, the geometry of a
turbine blade can complicate the dimension. Figure 2 shows the width dimension from a first stage X45 vane. The layer was non–conducting material.
In this case, the dimension can be easily to carried out with conventional eddy current technique. Fig 2: EC thickness dimension of the layer from a 1.

Design Constraints For The Wind Turbine Tower
ENG 1050 –Materials Selection Report
Abstract
After careful considerations of material properties with the objectives of the research (minimise cost and weight), the material that would be most
suitable for the wind turbine tower is low–alloy steel and for the blades, CFRP. Considering the design constraints, the tower is best designed with a
hollow circle frame with 5m (inner) and 3m (outer) radius which translates to a material cost of $4.96 million (tower only) and weighs 7893 tonnes.
CFRP is the most suitable material for the blade as it has the lowest density and high fracture toughness and fits the constraints. Additional costs are
based on anti–corrosion protection, CFRP production (based on blade length), transport and recycling commitments.
Introduction
Due to the dying ability of traditional fossil fuels to power the earth's power requirements, alternative energy sources – such as solar, wind, geothermal
and hydropower are beginning to supply the rapidly growing demand. Offshore wind farms, a clean energy source, are being introduced given their
consistent and relatively higher power output.
The purpose of this exercise is to design a wind turbine tower and blades to meet the service specifications for an offshore environment. This involves
manipulating the design – tower shape and dimensions, selected material while minimising the cost of construction and the weight. Given that the
turbines are to be offshore, we will also predict possible corrosion damages and

Solar Panels, Hydropower, And Wind Turbines
DISCUSSION
How Biomass Works
Solar panels, hydropower, and wind turbines are all well–known renewable resources. However, one of the most prevalent sources for energy is often
overlooked. Biomass is a renewable and sustainable energy resource that uses organic materials to generate electricity. ("Biomass Power Association.")
Biomass energy is made from any form of previously–living material. This includes any animal material or product, all vegetation, and even human
waste. Scrap lumber, forest debris, crops, manure, and even industrial wastes can all be utilized and turned into renewable energy through biomass.
Often leftover materials from factories such as paper mills are used to help sustain the renewable resource. However, this process tends to be
inefficient and unreliable (Mary, Booth), so frequently biomass energy is instead produced by cutting down forests or converting crops such as sugar
or corn into combustible fuels. Biomass is considered a renewable resource because organic material and waste will always exist. Whether this is
through forests, crops, or animals, as long as humans inhabit the earth there will be waste to utilize. [figure 2]
Although biomass is sometimes considered inefficient in comparison to other fuels, biomass fuels have two strengths when compared to widely–used
fossil fuels. The first reason is the time difference there is between fossil fuels and biomass. One example would be coal. In nature coal requires close to
400 million

Wind Energy and Turbines
Introduction In today's world, there are many different sources of energy that can be used to generate electricity. When you think of the word energy,
what comes to mind? For me, I think of having the ability to do wok, whether it is moving an object from one place to another, compressing a gas,
producing heat, sound, or light, and having the ability to power something. One very important source of energy that has become very popular in
todays world for a means of power generation is wind energy,wind power, or also known as a wind turbine.
What is Wind Energy? Wind is air in motion, and is caused by the uneven heating of the Earth's surface by the sun ("Wind"). Because of this, wind
energy has less impact on the environment then other energy sources. Therefore, wind can produce electricity through a turbine or windmill. A wind
turbine is a device that converts kinetic energy from the wind into electrical power. ("Wind Turbine") In order for a wind turbine to work there are
many properties that must be present such as: wind, wind speed, location with the right wind, as well as other characteristics that come to play such as
short and long term fluctuations and the distribution of wind direction.
History of Wind Energy Now that you know what wind energy is, it is time to look at where did the term wind energy originate from. To start, wind
energy has been around as early as 200 BC, and was used to ground grain or pump water. One of the first uses of wind energy was by

Divided Over Wind Turbines Analysis
The cost for renewable energy is halted for an endanger species. The text "Divided Over Wind Turbines" by Maria Glod is discussing how the
windmills should not be built because the low number of bats that are already left will die off due to the wind turbines. In the other text, "District

Case of the Proposed Jiminy Peak Wind Turbine Essay
1. Two commonly used methods of financial analysis are payback and present value. Payback determines the length of time for an investment to return
its original cost (1). Using the assumptions stated below the payback of the Jiminy Nick wind turbine with a cost of about $3.3 million would return the
investment in about four years time. Net present value summarizes the initial cost of an investment, the estimated annual cash flows, and expected
salvage value, taking into account the time value of money (1). A NPV calculation for the scenario SED is reviewing equals $7,697,286 minus the
investment costs of $3,318,000 totaling $4,379,286.

Not only is the wind turbine environmentally sustainable, it can lead to tremendous cost savings for the resort. Below are the advantages (3):
The turbine is able to generate energy 24 hours a day, 7 days a week. While the resort may not use all of the electricity that the turbine generates, the
excess electricity can be diverted to the power grid and sold resulting in additional money for the resort (approximately $161,000/year).
With a wind turbine, Jiminy Peak Mountain Resort will buy 2.3 million fewer kWh per year resulting in cost savings for the resort.
The resort will benefit from renewable energy production tax credits for 10 years.
The wind turbine eliminates the need for diesel fuel generated power.
The wind turbine eliminates gases such as CO2, SOx and NOx.
The turbine does not produce much sound at 200 yards away, only that equivalent to a quiet whisper.
3. While the wind turbine can be advantageous to Jiminy Peak Mountain Resort, the resort must also consider the disadvantages of erecting the turbine
prior to making a final decision (4).
The wind turbine is taller than the Statue of Liberty and its blades are more than 100 feet wide. Local residents may not want such a tall structure at the
top of the mountain.
The construction materials for the wind turbine would travel noisily through the local community which would add to the road

Working of Wind Turbines
There are a large number of literatures available on the study conducted to improve the working of wind turbines. Some of these researches have been
implemented practically while others are still in experimental phase. A literature was prepared by Md. Mahfouz Sarwar, Nazia Nawshin, Muhammad
Ali Imam and Mohammad Mashudon on "A new approach to improve the performance of an existing small wind turbine by using Diffuser." They have
studied the improved effect of diffuser on the performance of a small wind turbine system. They have analyzed two hollow structures: Nozzle and
Diffuser. Also by experimental setup they have proved that the wind speed in diffuser was greatly influenced by diffuser open angle, and speed
increases near the inlet region of it.
3.1 Selection of Diffuser Shape
Khulna University of Engineering & Technology (KUET) had done smoke–wire analysis on two types of hollow–structure models, a nozzle and a
diffuser. The experiments revealed that a diffuser–shaped structure can accelerate the wind at the entrance of the body. They examined the inner flow of
two typical hollow structures, namely a nozzle–type model that reduces the inside cross section and a diffuser type model that expand the inside cross
section downstream. The diffuser model has a remarkable effect on the collection and acceleration of the approaching wind. It has been found that the
wind tends to avoid the nozzle type model, while the wind flows into the diffuser type model as it is inhaled.

Risk Analysis: Onshore Wind Turbine
There is a rising commitment towards utilizing clean energy across the world. Wind turbines happen to be an efficient choice to meet some of the
demand on electricity. A group of wind turbines connected to each other by electrical cables forms a wind farm. A wind farm produces 17 to 39 times
the power it consumes, which is more efficient when compared to other forms of energy such as nuclear power (16 times) or coal (11 times) [1]. An
onshore wind turbine sits on a structural support usually made of concrete, called Foundation, the importance of a foundation is to transfer the
horizontal and vertical forces acting on the wind turbine to the surrounding ground. Whether the case is offshore or onshore, a wind turbine would

Risk assessment is the overall process of hazard identification, risk analysis, and risk evaluation [5]. Risk assessment provides an understanding of
risks, their causes, consequences, and their probabilities [6].
Hazard Identification is the process of finding, listing, and characterizing hazards.
Risk Analysis is a process for comprehending the nature of hazards and determining the level of risk.
Risk Evaluation is the process of comparing an estimated risk against given risk criteria to determine the significance of the risk.
A decision has to take place based on risk evaluation in order to mitigate or control the risk. This step is known as Risk Control. Before
implementing risk control measures, the level of risk has to be determined in order to decide which hazard to start treating [5]. One of the conventional
methods used to rank or prioritize risks is the Risk Matrix shown

Wind Energy : Land Based- Large Turbines
Wind Energy: Land Based– Large Turbines
Winds are caused by the uneven heating of the atmosphere from the sun, irregularities of the earth's surface and the rotation of the earth. This wind
flow can be used to generate mechanical and electrical power when used by wind turbines. Wind energy is a renewable resource that does not create
pollution. Wind energy is derived from natural wind speeds of at least 10 mph. The incoming wind is harnessed by large wind turbines that are used
to move blades. The movement of these blades results in the turning of a drive shaft and generator to create clean electrical power. Awind turbine is the
opposite of a fan. Instead of using electricity to make wind, wind turbines use wind to make electricity. Wind turbines convert the potential energy in
the wind into kinetic energy that results in mechanical power– The turning of the blades and drive shaft. The mechanical energy can then be used for
traditional tasks such as grinding grain or pumping water. Modern wind turbines use generators to convert this mechanical power into electricity that
can power homes, businesses, schools and other buildings. Wind turbines are often grouped together into a single wind power plant also known as a
wind farm, and generate bulk electrical power. Electricity from these turbines is fed into a utility grid and distributed to customers, just as with
conventional power plants. Wind turbines come in a variety of sizes and power ratings. Utility–scale turbines

Essay on The Importance of Wind Turbines for Renewable Energy
The American inventor Charles F. Brush invented the first automatically operated wind turbine in 1887. [1] Since then, multiple developments have
contributed to the design of today's modern wind turbine. And when grouped together into a wind farm, wind turbines are becoming an important
source of renewable energy.
HAWT blades are designed like airplane wings in order to use lift to capture the wind's energy. Theairfoil design that they use makes one surface of
the blade rounded, while the other is smooth and flat. [3] When air passes through the blades, a difference in pressure is created between the top and
bottom of the blade. The introduction of the blade into airflow acts like an introduction of a force and causes the streamlines of ... Show more content on

The main purpose of the gearbox is to increase the rotational speed of the blades to the generator. In order for the electrical generator to perform
efficiently and effectively, the input speed must be very fast. The blades are not able to turn fast enough due to the centrifugal strain of high speeds.
[6] The gearbox uses multiple gears and gear trains in order to provide speed and torque conversions that are necessary. These conversions are
dependent on the gear ratio of the gearbox.
Most of the mechanical energy that is produced by the rotating blades is transformed into electrical energy via the generator. The generator, through the
process of electromagnetic induction, produces an electrical voltage that will cause a current to flow out of the generator. As the rotor spins the shaft,
the shaft spins the coil of wire held within the generator. The coil is surrounded by an assembly of permanent magnets that produce a voltage when the
coil is spun inside of them. [7] This voltage is what drives the electrical current through the power lines for distribution.
The yaw controller is responsible for controlling the angle between the rotor and direction of wind (yaw angle). Varying wind direction becomes an
issue for the power–generating abilities of turbines. In order for the turbine to produce the most power, the turbine's horizontal axis must be parallel to
the wind direction. The yaw controller is able to turn the

The Architecture Of Wind Turbines
1.0–Architecture of Wind Turbines Wind turbines are commonly thought of not being complex; however, turbines are composed with much more than
meets the eye. Starting at the base which has drastically changed and will continue to change as new technology arises. The base is the most important
part of the wind turbine as it takes forces from all sides, and is the hardest part of a turbine to change because the whole turbine has to be taken down.
With today 's technology the base can withstand loads and stress from various directions; therefore, being one of the most important aspects of a wind
turbine.
The yaw motor is next in line, and it moves the turbine 360 degrees, a full circle, and this technology is there to accommodate for wind coming from
any direction. It has increased productivity, and is key to the production of energy.
The gearbox and generator are the most important aspect of a wind turbine because without, energy would not be produced. With better technology
increasing the production of energy. There have been different three stages to the development of wind turbine technology; stage 1, which consist of
constant speed turbine with a squirrel–cage induction generator; stage 2, consist of a variable speed turbine with a squirrel–cage induction generator
and fully–rated frequency converter; stage 3, which consist of a variable speed turbine with a wound–rotor induction generator and partially–rated
frequency converted. Advancement in these stages has

Vibration Control in Wind Turbines: A Comparative Study Milad Rezaee1 and Aly Mousaad Alyп
ЂЄ2 1, 2 Department of Civil and Environmental
Engineering, Louisiana State University, Baton Rouge, LA, USA Abstract. Recently, the increased energy demand has led to explorations in other
sources, particularly in renewable energies. Wind energy is one of the cleanest sources that plays a significant role in providing sustainable energy.
Wind turbines, as wind energy power plants, are considered tall and slender structures, and depending on their location, which can be inland or offshore,
can be exposed to high wind and/or strong wave loads. These loads can exert unwanted vibrations on the structure that may have detrimental effects on
energy production. The current paper reviews some of existing methods to control these vibrations and investigates the influence of using different
methods to suppress the motion of a wind turbine tower. In this study, the capability of the tuned mass dampers, tuned liquid column and sloshing
dampers, and viscous dampers to decrease the tower's vibration are evaluated. Finally, a comparison among these devices is made and
recommendations on the application of each technique are suggested. Based on the results presented, viscous dampers can reduce both displacement
and acceleration of the tower better than other types of dampers, for the same control effort (total control force). Nevertheless, the use of viscous
dampers may require space considerations,

It is considered green energy because it uses resources the Earth will replace and does not pollute nor harm the environment (Alliant Energy). Fossil
fuels, which are fuels found under the Earth's ground, such as petroleum, cannot be replaced and cause large levels of pollution (SF Environment).
One of the renewable sources causing the most controversies in Puerto Rico is the wind. In order to use the wind to generate power, also known as
Aeolic energy, wind turbines are needed.
According to research done by Discovery News, in January 25, 2013, the top 10 countries, by order of most demand and use of wind energy, are:
China, United States, Germany, Spain, India, Italy, France, Canada, Brazil, and Denmark. All of these countries are investing money inwind turbine
projects because, in the long run, it is going to benefit them from both the economic and ecofriendly point of view (Discovery News). In addition to
these top ten countries in the world, there are more countries that have, or are, investing in these types of projects, since this is the future and correct
path for the use Renewable Energy as a replacement for fossil fuels. Fossil fuels are harming the environment to the point where in a short amount of

Wind Power And The Wind Turbine System
Abstract
Wind force is still the most encouraging renewable energy in the year of 2013. The wind turbine system (WTS) began with a few tens of kilowatt
power in the 1980s. Now, multi megawatt wind turbines are widely installed even up to 6–8 MW. There is a widespread use of wind turbines in the
distribution networks and more and more wind power stations, acting as power plants, are connected directly to the transmission networks. As the grid
penetration and power level of the wind turbines increase steadily, the wind power starts to have significant impacts to the power grid system.
Therefore, more advanced generators, power electronic systems, and control solutions have to be introduced to improve the characteristics of the wind
power plant and make it more suitable to be integrated into the power grid. Meanwhile, there are also some emerging technology challenges, which
need to be further clarified and investigated. The global electrical energy consumption is still rising and there is a steady demand to increase the power
capacity. The production, distribution and the use of the energy should be as technological efficient as possible and incentives to save energy at the
end–user should be set up. The deregulation of energy has lowered the investment in larger power plants, which means the need for new electrical
power sources may be very high in the near future. Two major technologies will play important roles to solve the future problems.
One is to change the electrical

The Wind Power Of Wind Turbines And Wind Farms
I.The nature of noise related symptoms in residents who reside within a certain proximity to wind turbines and wind farms.
Over the past several decades, there has been a resurgence in wind power. This technology is a clean renewable energy source that does not contribute
to global warming nor does it create any harmful wastes. As communities look to identify safe renewable energy sources many have turned towind
power; inspired by the numerous benefits and perceived benign risks many have attempted to harness wind power through wind turbines and wind
farms. As the Sun heats the Earth it creates wind. Due to the changing seasons and moving cloud coverage, the sun heats the Earth unevenly and this
uneven heating, in addition to the Earth 's rotation, causes warmer air to move toward cooler air resulting in wind. Although wind power is not new,
technological advancements have altered the image of the traditional windmill and have created new obstacles and environmental concerns for local
residents.
Wind power is harnessed using wind turbines, which transforms the energy into electrical power. Wind turbines are typically designed either on a
horizontal–axis or a vertical–axis. According to the U.S. Environmental Protection Agency, "horizontal–axis wind turbines have either two or three long
blades that collect the energy in the wind and convert it to electricity." Additionally, "the blades spin when the wind blows over them and the energy of
motion contained in the

C. The VAWT is better than the HAWT inwind power plants because VAWT significantly requires less installation room decreased mechanical
vibrational stress, much higher output efficiency, and is a lot easier to construct.
II. BODY
A. Although the HAWT are mostly for the large scale industries and remote areas, in the urban region and small scale industries target mostly VAWT.
The flow of the wind in urban areas is less, area occupying by the VAWT motor and blades is less because this part is small and vital to run thewind
turbine, and the noise pollution is less due to small design model and flexible composite blades. Not only acoustic pollution is less, but also the
structural design and safety problems restricts the usage of HAWT in urban areas (Yang Zhong
–Jia). The blades of HAWT a must be made of are
metals and the ratio of the wind blade length, thickness and width are more which leads to more stress on the blades and motor rotating the turbine.
B. Turbine Blades and internal parts such as motors are the main part of the Windmill. Materials used in the HAWT lead to effect more cost. Unlike
the materials of VAWT, the materials of HAWT are made of high composites metals and steel blades, power required to store the energy in the end in
the generator is more, and it must be installed near offshore or remote areas (K. A. Brown*). However the turbine blades made up of composite
materials such

If one were to look at human related variables, then the third most bird related mortality variable would be transmission line collisions, which is
responsible for more than 16 million bird deaths (Calvert et al, 2013). The article by Calvert et al (2013) suggests that there are other variables that
contribute higher bird mortality than wind power. The article by Pagel et al (2003) is a collection of reports by industry on bird death by wind turbines,
while the article by Calvert (2013) is an estimation based on reports. Both support either sides of the argument, thus causing more controversy.
Since the wind industry acknowledges that wind turbines have the potential to harm or cause bird mortality, the industry has put in resources to
resolve this issue. Collaboration between TansAlta Corp. and the University of Calgary have found a way to reduce bat mortality by 60% (Jones,
2013). They were able to achieve this by studying the interactions between bats and wind turbines. They found that bat mortality were not the result
of external injury, but by lung damaged through a drop in air pressure (Jones, 2013). The drop in air pressure was caused by the low rotation
frequency of the turbine blades (Baewald et al, 2008; Jones, 2013). This finding has been supported by other research papers such as the one by
Baewald et al (2008) Barotrauma is a significant cause of bat fatalities at wind turbines. Their findings were that 8% of bats had only external

The Wind Turbines Are A Dominant Method Of Harnessing Wind...
This paper discusses how scientists can help bring wind power into urban areas with limited space such as London, and make wind energy a
sustainable energy resource. Three–blade wind turbines are a dominant method of harnessing wind power, but this technology has drawbacks which
make it unsuitable for placement in London. Small Wind Turbines, owned by individuals and/or communities have attempted to fill the gap, but are
only capable of supplying lower levels of power than a city demands. This paper assumes that wind power will continue be used in combination with
other (renewable) energy sources, such as solar, tidal or nuclear power to meet the UK's future energy needs and sustain at least an equivalent lifestyle
to now.
3–blade wind turbines are the dominant wind power technology used by the UK and they are a strong force in the UK renewable energies market
(Renewable UK, 2014). As such, the market has invested in wind energy and drives a profitability mentality to renewables. There is public support for
using wind energy generally, but also concerns about the effects of (in particular) 3–blade wind turbines and Small Wind Turbines on human and
animal health, noise pollution, and their visual impact were they placed in sight of people's homes (Tatchley et al., 2016). These market forces spur on
innovation into wind energy which makes it more accessible.
Using wind turbines has helped put the UK on track to achieve deriving 20% of its energy needs from renewable sources

Internet Of Things : Applications Of Wind Turbine Industry
Internet of Things: applications in Wind Turbine Industry
Abstract
Over the past decade we have seen a rapid adaptation of ubiquitous internet–enabled technologies in many fields, from home security to public transport
to monitoring natural resources. The proliferation of these devices, enabled by advances in sensor technologies, have provided us with a platform
where devices can communicate with each other and execute management tasks without human oversight. In this paper, we look at potential
applications for Internet of Things based solutions in wind turbine industry. A major bottleneck observed in the functioning of wind turbines is the
premature gearbox failures that result in unexpected maintenance shutdowns and related costs. We see how IoT, coupled with debris monitoring
systems currently in place, can help address this issue.
Keywords: Internet of Things, MetalSCAN, Wind turbine gearbox, cloud computing
1. Introduction
Wind mills have existed as part of human civilization from as early as first century, and have been used to harness the power (KE) of winds. In
present day, wind turbines are used to convert the kinetic energy of wind to electric energy that can be stored and distributed far and wide as
controlled energy. There has been a huge rise in interest and investment in wind turbines and wind farms, as it represents a renewable source of energy
that is plentiful, widely available and has much less effects on environment compared to non–renewable sources.
