Wind Turbine Essay

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.

As the global supply of fossil fuels becomes steadily lower, need is growing for new energy sources that are beneficial to the environment and cost-effective. Wind power is one solution to this need. Wind turbines require significant investment, but are cost-efficient in the long term. If construction of turbines is sufficiently increased, the wind may be able to in the future provide a very major portion of global energy.

​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.

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

The lab tested various properties associated with wind turbines while measuring the effect on the power. It was shown that wind turbines can supply a significant amount of energy and power. This wind energy has an important application with wind turbines across windy areas of the United States. These turbines can provide power as a replacement for nonrenewable resources. Although wind energy might not be the most vital form of energy currently, it could become a very important alternate energy source in the near future. Wind turbines can be placed all across the United States wherever there is a strong amount of wind. When talking about implementing wind energy there are a lot of things to think about.

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.

As long as you don’t have much problems with the factors shown above, you can build yourself a wind turbine. To construct these things, the wind turbine consists of three basic parts: the tower, the nacelle, and the rotor blades. The tower itself is either a steel lattice tower almost the same as an electrical tower, or a steel tubular tower with an inside ladder to the nacelle. The first step in constructing the wind turbine, is to have a tower. The steel parts are usually made off site in a factory, however, they are usually built on site. The parts are bolted together, and as usual, keeping the tower horizontal until placement. Next is the fiberglass nacelle is installed. It’s stuff inside such as the main drive shaft, gearbox and blade pitch and yaw controls are created and mounted onto a base frame at a factory. The nacelle is a strong, hollow shell that has the inner workings of the wind turbine. Towers do not have “guys,” which are cables used for support. They are mostly made out of steel that has been coated with zinc alloy for

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.

Along with these benefits come many practical difficulties associated with offshore wind projects. Offshore projects are expensive, particularly when paralleled with those projects which are land-based. The surface of ocean is a harsh place to maintain and build these structures. Due to this reason, high winds that carry larger amounts of energy threaten the steadiness of wind turbines which causes installation to become much more rigorous and costly. Furthermore, it also fetches the need for monitoring which is an expensive and automated system for maintenance. Underwater topography presently describes the viability of installation as most current models use foundations rooted directly into sea beds that are shallow.

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

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]

Since 1980’s wind turbines have noted a remarked progress making the whole sector and technology mature in order to enable the rapid growth on the market. This is justified by Fig.3 where it is observed that from 1996, the growth is steadily increased till 2012 and is still growing. From then till now, the cost

Wind power has grown at an average rate of 21% in 2011 and 19% in 2012 [1]. Energy can be extracted as electricity from this wind using wind turbine and some aspects of High altitude wind turbines are discussed in this report.

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,
