Essay on Renewable Energy Wind Energy - 946 Words

Chapter 1 Introduction 1.1 Motivation Recently, wind power has gained greater attention with respect to sources of renewable energy due to the maturity of the technology and its relative cost competitiveness. Wind power farms (WPFs) are scattered in remote areas (onshore and offshore) selected by the wind speed, water depth, and distance to shore. It is important to develop technology to monitor WPFs with higher capacities as the size and number of wind turbines in a WPF is continuously increasing. In order to provide real-time control and monitoring, reliable bi-directional communication infrastructure is needed. According to their needs, most turbine manufacturers have developed their own monitoring and control systems due to an absence†¦show more content†¦1.2 Scope of the work The dissertation is divided into three main parts. In the first part, we proposed the hierarchical communication network architectures that consist of a turbine area network (TAN), farm area network (FAN), and control area network (CAN) for WPFs. The wind turbines are modelled based on the logical nodes (LN) concepts of the IEC 61400-25 standard. The WPF communication network is configured with a switch-based architecture where each wind turbine has a dedicated link to the wind farm main switch. Servers at the control center are used to store and process the data received from the WPF. The network architecture is modelled and evaluated via OPNET. We investigated the end-to-end (ETE) delay for different WPF applications, and our network architecture is validated by analyzing the simulation results. In order to meet the growing demand of large-scale WPFs, integration of high reliability, high speed, cost effectiveness and secure communication networks are needed. In the second part of this dissertation, we proposed the Ethernet passive optical network (EPON) as one of promising candidates for next generation WPF. Critical communication network characteristics such as reliability, mean downtime, optical power budget, path loss and network cost are evaluated and compared with conventional switched-based architectures for five different architectures.Show MoreRelatedThe Effect Of Wind Energy On Renewable Energy820 Words   |  4 PagesEveryday witnesses increased demand in energy, which requires further investigations on available sources of energy, especially renewable energy that was highlighted in the last decades as per environmental and sustainability demand. Wind energy is one of the cleanest energies that received the attention of researchers and investors because of its av ailability with low running cost. According to the World Wind Energy Association (WWEA, 2015), wind energy is currently the fastest-growing source ofRead MoreRenewable Forms of Energy: Wind Energy Essay1320 Words   |  6 PagesRenewable forms of energy are becoming more and more necessary for a sustainable future. Wind energy is a form of energy that is becoming more and more popular, and it offers a way for people to harness energy from something natural to create electricity. Wind energy in addition to other sustainable forms of creating energy are going to start taking the place of fossil fuels as people realize the true benefits of using them. There are many benefits of using wind energy in comparison to using fossilRead MoreEssay on Wind - A Renewable Energy Source525 Words   |  3 PagesWind - A Renewable Energy Source Wind is called a renewable energy source because wind will continually be produced as long as the sun shines on the earth. The sun’s contribution to wind energy deals with converting air into heat or cool wind. Wind is produced by the irregular heating of the earth’s surface by the sun. On land, the warm air spreads and goes up in the sky, in the water, heavier and cooler air moves in to take the warm air’s place, thus providing local winds. This powerRead MoreRenewable Energy: Wind Power Essay582 Words   |  3 PagesWIND POWER Wind is one type of renewable energy that can be developed to generate free and clean energy replacing the one that be renewed and cause the pollution such as fossil fuel. Wind energy can be extracted by using the suitable wind turbine that is suitable with the current wind speed at observe location which is eastern coast of peninsula Malaysia. Generally, Malaysia has a potential to use the wind as alternative energy because of the wind speed in Malaysia can reached until 12 m/s andRead MoreEssay on Wind power and future of renewable energy1392 Words   |  6 PagesWind power and future of renewable energy Abstract: Due to the development of technology around the world, the need of energy is increasing every year. But, what would be the best way to produce energy without polluting the air, or depleting fossil fuels? Renewable energy would also be the best solution for this problem. Of the available sources of renewable energy, wind power shows much promise. Wind turbines have been used through many generations, and the technology continues to develop.

As many reliable energy’s rise on demand and expense like oil, coal, natural gas and nonrenewable fossil fuel that draw on limited resources which will eventually diminish. Looking at all the power plants and the millions of cars that exist in the streets today and many more technologies and industries that are polluting the air it is safe to say we may be going the wrong way intoRead MoreWind Power Generation : Renewable Energy Source1443 Words   |  6 PagesWind Power Generation In the 21st Century, fossil fuels are becoming increasingly important, with the demand for these resources increasing, despite the knowledge that they are finite. Globally, the annual consumption of fossil fuels is eleven billion tonnes, with crude oil reserves waning at a rate of four billion tonnes per year. If these figures experience little change in coming years, oil reserves are estimated to completely deplete by 2052 (Ecotricity.co.uk, 2014).

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
