Wind turbine technology is well established within the renewable energy market. Many customers seek to install new turbines with higher power output especially for offshore wind farm installations. However designers must ensure the structural integrity of these increasingly large and heavy wind turbine rotors without degrading their performance.
Abstract This dissertation is the documentation of the design and development of a sustainable wind energy conversion system to be employed as a stand-alone electrical energy generator for isolated communities and dwellings.
Wind turbines use large blades to catch the wind. When the wind blows, the blades are forced round, driving a turbine which generates electricity. The stronger the wind, the more electricity produced. There are two types of domestic-sized wind turbine.The need for designing a Small Wind Turbine (SWT) stems from two global issues; the first issue is climate change, and the increasing urgency for sustainable energy practices to be developed and implemented. The second issue is finite fossil fuel supplies, and the need to replace existing energy sources with renewable forms.A small, vertical-axis wind turbine has been mechanically coupled to a positive displacement pump for pumping from shallow wells or lakes. The 4-kW turbine is 5.5 m high and has an equatorial radius of 4.5 m. Power is transferred through an electric clutch, which allows the turbine to be started in a no-load condition (Fig. 8).
The FuturEnergy AirForceTM 1 and AirforceTM 10 domestic wind turbines are ideally suited to battery charging, water or space heating, local off-grid network or grid tied applications. All conversion and control systems and accessories are available to make installation and commissioning of wind turbines for home trouble-free.Read More
Constructed from lightweight, waterproof cast aluminum, this home wind turbine kit is perfect for households that are out in the country and in areas with regular heavy winds. This model will start picking up at wind speeds of just 5 mph and it has a power output capacity of 1500 watts. You can store all the excess power that it produces on the batteries through a charge controller or inverter.Read More
Wind turbines are energy conservation devices used to harness the power of wind for electricity generation. The primary component of a wind turbine is the rotor. The rotor transforms the kinetic energy of moving air into mechanical energy, where it will then be converted into electric power. The ability of the rotor to convert a maximum proportion of wind energy flowing through the swept area.Read More
Within a wind farm, multiple turbine wakes can interact and have a substantial effect on the overall power production. This makes an understanding of the wake recovery process critically important to optimizing wind farm efficiency. Vertical-axis wind turbines (VAWTs) exhibit features that are amenable to dramatically improving this efficiency.Read More
The wind energy industry is moving towards its target of supplying 14-16% of the total Europe energy demand by wind energy by way of installing newer wind energy generation devices throughout Europe. In 2013 alone, a total of 418 offshore turbines came into existence in Europe, with total wind capacity connected to the grid with a rise of about 34% over the previous year. By the end of 2013.Read More

The current generation of wind turbines that are being deployed around the world features, almost exclusively, a three-bladed rotor with a horizontal-axis configuration. In recent years, however, a resurgence of interest in the vertical-axis wind turbine configuration has been prompted by some of its inherent advantages over horizontal-axis rotors, particularly in flow conditions that are.Read More
The objectives of the dissertation are focused on the development of a methodology and specific tool for the investigation of possible existing wind blade geometry adjustments. The novelty of the methodology presented in the thesis is the multiobjective perspective on wind blade geometry optimization, particularly taking simultaneously into account the local wind conditions and the issue of.Read More
Wind turbines, which have been used for more than 3000 years, convert the kinetic energy of wind into mechanical energy. Although for many years the main application of wind turbines was limited to windmills, due to the oil crisis in 1973 and the sudden increase in the price of oil, the wind turbine technology was supported by the.Read More
