Wind Power Generation and Wind Turbine Design Wei Tong

That technology would seem to pair well with a new gearbox design from ExRo that allows turbines to much more efficiently turn fluctuating air currents into stable electricity. Turbine blades are specially designed for pushing purposes. Gamesa has shown its new wind turbine with 2.5 MW of unitary power: the G114-2.5 MW at the American Wind Energy Association's Windpower 2013 conference and exhibition (5-8 May in Chicago). We've already covered Catch the Wind's laser-based system for creating 3-D maps of wind direction and speed. The new turbine is The bigger rotor and the higher unitary power of Gamesa's G114-2.5 MW turbine, designed for use in Class II winds, reaches the highest efficiency and profitability, by optimizing the cost of energy in the 2.0-3.0 MW product segment. It comprises a steel Only a few prototypes have been built so far, but the inventors, Johan Smit and Dhiradi Djairam, think that if their design takes off, it could be a boon to wind power in cities, where massive turbines aren't an option. Plants originally designed to provide baseload will in future have to operate on a load-following or cycling basis, ramping up and down at short notice. The wind turbine design is something which is increasingly worked upon to suit the needs and improve the production of energy released from using them. This story from Science Daily provides a glimpse into how future wind turbine towers might be designed, using concrete instead of steel. For example, according to the U.S. Forcing coal and gas-fired power plants to ramp up and down more frequently to compensate for the growing number of wind farms connected to the power according to a recent study funded by the U.S. Harnessing the wind's energy is the objective of a new project, which aims to provide an important breakthrough in offshore wind industrial solutions. Wind sensors are also there in large turbines. Horizontal axis of wind turbines is equipped with electrical generator, blades and rotor shaft. Presently wind turbines use a mechanical transmission to smooth out the speed at which energy is delivered to an internal generator. This seems like a no-brainer considering the enormous possibilities for power generation that recent studies are highlighting. Instead of generating electrical energy from the mechanical energy of the rotating blades, this device, called a Ewicon (short for Electostatic Wind Energy Converter) skips the whole mechanical energy part.
