Wind Turbine Essay

​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.

In over 20 years of electricity generation with more than 100,000 machines installed worldwide, no member of the public has ever been injured during the operation of a wind turbine. These stats recorded show that the wind turbines are very safe and have a good reputation.

One of attracting concepts has been the use of Turbosail principle to produce lift from fixed cylinders in various engineering applications. With emerging innovative Turbosail type wind turbine technology, it is important to determine power performance and characteristics of such generators as correctly as possible.

Wind turbine electrical model WT3E should have ωPmin < ωP20 < ωP40 < ωP60 < ωP100.

Imagine getting free electricity, or electrical company’s paying you instead of you paying them, today’s windmills just might make this possible. Windmills dating back as far as the 1400’s have been used to turn wind into useable energy for grinding and pumping. Today’s windmills turn turbines to make electricity. They are popping up all over the United States, but the United States is way behind other countries in the development of wind energy. Countries like Denmark, Germany and the United Kingdom are investing billions of dollars into wind energy, including off shore wind farms. Germany is holding the top spot in the production of wind-generated electricity. Denmark, being one of the smaller countries in Europe, produces twenty percent

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 energy is captured and converted into energy by lift. The propeller blades are designed to have one side with an arch and the other straight. As wind passes over a blade, air is forced to travel a greater distance over the arch of the blade, creating of low pressure above the curve. This unequal pressure difference forces the blades to rotate in the direction of less pressure. The mechanical force generated by the movement of the propeller is then used to rotate a turbine to generate power.[3]

The properties of bricolage and breakthrough were mirrored vividly by the development of wind turbines in Denmark and the US. Starting with an early crude design, Denmark witnessed the incremental development of its wind turbines technology with

Everyone knows that the wind is one of the most significant factor of weather and climate because of its role in influencing the distribution of energy and moisture between the parts of the globe. Recently, people have begun to exploit the wind energy which is witnessing the fastest growth in the world. In fact, this source of energy is growing rapidly in all parts of the world. So, most of governments are trying to use wind power for different aspects. In addition, two decades of efforts to achieve technical progress has led to the production of very sophisticated wind turbines which are adjustable, easy and quick to install. Wind power may have many disadvantages, but the advantage of wind energy is more than the disadvantages. So, there are many environmental advantages of wind power such as renewable source, reduction of greenhouse gases, reduction of water consumption, and taking a small space in the land.

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the

Offshore wind power has become a need of the hour in renewable energy production due to the rising prices of oil and continually increasing demand for a separate energy sector. Offshore wind has the prospective to deliver at least four times the current U.S. demand of energy, as per mentioned by the Global Wind Energy Council. However, there are many challenges and advantages that are significant for us to comprehend.

We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

An world reliant on the burning of fossil fuels for heat, energy, and food, it a world with an expiration date. The affects of this dependance are already being felt today worldwide. The worst part is that these affects hitting the underdeveloped countries the hardest and they are the ones that have been able to take advantage of these energy sources the least. Fossil fuels have been contributing to the increase in carbon dioxide levels in the atmosphere which is contributing to global warming, the rising ocean acidity, and heath issues. For these reasons it is imperative that we cut our ties with fossil fuels and start heading in an environmentally conscious direction. At the for front environmentally friendly options is the harnessing of the wind. Wind is an energy source that humans have historically benefitted from to explore the world, prepare food, and pump water. These days we have implemented the use of giant turbines that allow the wind to turn their giant blades to generate electricity. To dive deeper into discovering the best way to harness this energy will require to look at past wind technologies, the advantages and problems with our current turbine designs, the new innovations and ground breaking designs.

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 spin motors,

Wind turbine is a device that converts kinetic energy stored in wind to electrical energy using electrical generator. Before invention of electricity Windmill was used to convert energy of wind to rotational mechanical energy. In history we have seen many kind of drag and/or lift type of wind turbines. Currently mostly used wind turbines are three bladed Horizontal axis Wind turbine and Darrieus(or Egg-beater) type wind turbine. Majority of the modern wind turbine have can generate electrical power of 1.5 to 5MW [2]. We can define capacity factor as ratio of total wind energy extracted within a year to the total theoretical maximum power of a given wind turbine. Capacity factor depends on many factors but one on them is very low wind speed which is not enough to run a wind turbine. Wind speed increases at higher altitudes from the earth surface. Thus more energy can be extracted from the wind at high altitudes and in addition to that we have higher capacity factor because of more continuous winds. At 100m height estimated global wind power is about 230 TW [3]. We can get high amount of wind energy (80 GW as in [4].) at
