![]() The decrease is due to lower prices for wind turbines and a shift towards China. The turnover of the wind sector worldwide reached 40 billion Euros (55 billion US$) in 2010, after 50 billion Euros (70 billion US$) in the year 2009.52 countries increased their total installed capacity, after 49 in the previous year. In the year 2010, altogether 83 countries, one more than in 2009, used wind energy for electricity generation.All wind turbines installed by the end of 2010 worldwide can generate 430 Tera watt hours per annum, more than the total electricity demand of the United Kingdom, the sixth largest economy of the world, and equaling 2.5 % of the global electricity consumption.To read about the History of Wind Energy, click here Global Wind Energy Market Market Overview Market Research The History of Wind Energy The overall structure of wind power generation through DFIG as shown in the figure below. Therefore, the losses in the power electronic converter can be reduced, compared to a system where the converter has to handle the total power. This is mainly due to the fact that the power electronic converter only has to handle a fraction (20-30%) of the total power as the converters are connected to the rotor and not to the stator. ☓0% of synchronous speed, the doubly-fed induction generator(DFIG) can be an interesting solution. It is the most popular and widely used scheme for the wind generators due to its advantages.įor variable-speed systems with limited variable-speed range, e.g. In order to overcome the problems associated with fixed speed wind turbine system and to maximize the wind energy capture, many new wind farms are employing variable speed wind energy conversion systems (WECS) with doubly-fed induction generator (DFIG). Wind energy is one such renewable energy source that harnesses natural wind power.Ĭlick on Wind Energy Background to read more about wind energy. Renewable energy is also called "clean energy" or "green power" because it doesn’t pollute the air or the water. ![]() Harnessing renewable alternative energy is the ideal way to tackle the energy crisis, with due consideration given to environmental pollution, that looms large over the world.The use of wind to provide mechanical power came later. We have been using wind power at least since 5000 BC to propel sailboats and sailing ships, and architects have used wind-driven natural ventilation in buildings since similarly ancient times.3.1 Doubly-fed Induction Generator: Search Strategy.
