Electricity generation through small wind turbines is gaining worldwide popularity. However, studies that describe and analyze this source of energy are still scarce compared to those that analyze the medium and large wind turbines. Therefore, the present study aimed to analyze the National Advisory Committee for Aeronautics ( NACA ) blade profile considering its design adequacy to be applied to the design of the small horizontal-axis wind turbine blades. The number of rotation per minute (RPM)...

Renewable energy resources are becoming an increasingly important part of our total energy demands due to the depletion of fossil fuels and the emergence of global warming. Wind turbines are one type of renewable resource that is very usual in the South Texas region. It is a fact that wind power is the best dilute and unpredictable source of energy that works with efficiency of great importance in the conversion of this energy to electricity. Our research was to add shrouds by means of computer...

In order to reduce environmental pollution, reduce dependability from foreign energy sources, and avoid the uncertainty associated with an unpredictable rise in the price of oil, the use of alternative forms of energy is in worldwide demand. A popular and rapidly developing alternative form of energy is wind energy. The use of wind energy on a naval ship is the subject of this thesis. A preliminary feasibility study has been undertaken in order to evaluate wind energy potential and drawbacks....

Topic: Wind turbines -- Design and construction
This thesis is part of a larger project that will demonstrate the feasibility of powering a commercially sized 7.5-ton cooling system. Excess cooling will be stored thermally using ice. This system has the potential to be used in military bases to reduce energy costs and fossil fuel consumption. A scaled down version would be suitable for data centers and forward operating bases where the transport of fuel can be costly and dangerous. The system will be built and operated at the Turbopropulsion...

In this thesis, we emulate a Wind Turbine Generator by driving a Doubly Fed Induction Generator (DFIG) via a DC motor with variable input torque capability. The two circuits of concern are the DFIG and Supply-side circuits. They are electrically coupled with back-to-back Space Vector Modulators (SVMs) that are coupled through a DC Link consisting of a capacitor bank. The SVMs, with DC Link, provide bi-directional power flow between the DFIG rotor and Supply-side power supply. The Supply-side...

The project aims at developing a system which makes use of wind, piezo and solar energy for rural and urban electrification. This project cuts down the floor space used by conventional wind mills and solar panels. This configuration allows the three sources to supply the load depending on the availability of the energy sources. Energy is being generated from the three sources such as solar energy, wind energy and piezo electricity and in turn is being generated from the sun light, wind, and...

Renewable energy sources could be the main contributor to fulfilling the world’s energy requirement. Wind energy is grabbing the world’s attention due to its abundant nature and reliability. Wind energy is a prominent renewable energy source due to its availability and higher reliability. Despite the aforementioned benefits, there are some challenges such as wind measurement and prediction due to the turbulent nature of the wind. Lidar ( light detection and ranging ) technology is used in...

The increase in wind energy over the last decade has depicted a significant development in onshore and offshore wind turbine designs. Wind turbine designs are highly dependent on aerodynamic properties of lift and drag. There is normally an iterative process consisting of numerical design, prototype construction, testing and optimisation, calibration of computational flow models on the path to commercialisation. Theoretical turbine models are usually validated or optimised by the assessment of...

Establishing a low carbon energy mix to reduce the acceleration of climate change is key for countries, organizations and industries providing services and producing goods for public consumption. Establishing a new energy source for the purposes of satisfying energy needs is a challenge that has many dimensions. Most endeavours to establish alternative energy sources in developing countries face unique challenges that may render their establishment as a reliable energy source unsuccessful. Wind...

Currently, the quality of supplied power is important to several customers. Power quality is a service and many customers are ready to pay for it. In the future, distribution system operators could decide, or could be obliged by authorities, to supply their customers with different PQ levels and at different prices. A new device that can fulfill this role is the unified power quality conditioner (UPQC), composed of a power-electronic series main unit installed in the medium-voltage/low-voltage...
