How Wind Turbine Improved the World

WIND TURBINE

INTRODUCTION:

Windmills are incredible creations that have its importance in our history. Early pioneers utilized windmills for pumping water out of the ground and provide the water for their cattle's over a century. Throughout the years, diverse outlines and varieties were made to make the windmill run more effectively. In spite of the fact that there have been many plans made, a large portion of the windmill parts still remained unaltered.

Now-a-days the handling of “Electricity” has been increased rapidly. Due to this the “Fossil Fuels” are getting extinguished day-to-day. So we need to choose for an alternate source of energy that is Renewable Source. Among the Renewable Sources “Wind Energy” is one of them.

Windmills employ the kinetic energy from the wind and convert it to electrical power. Wind speed, type of rotor, type of generator, noise minimization and load, and control approach are the additional key turbine design considerations. Additionally, current trends, determined by the operating administration and the nature's domain, include improvement of low-cost, megawatt-scale turbines and lightweight turbine outlines. Whereas turbines working at constant rotor speed have been overwhelming up to now, turbines with variable rotor rate are getting to be progressively more normal in an attempt to optimize the vitality capture, bring down the loads, get better power quality, and empower more developed power control characteristics. The first practical windmills were built in Sistan, Iran, from the 7th century.

... at high altitudes. The height of the tower varies depending on the location. Areas with lower wind speeds may require a taller tower.

The wind passes over the blades creating lift (like an aircraft wing) which causes the rotor to turn. The blades turn a low-speed shaft inside the nacelle: gears connect the low speed shaft of the rotor with a high speed shaft that drives a generator. Here, the slow rotation speed of the blades is increased to the high speed of generator revolution. Some wind turbines do not contain a gearbox and instead use a direct drive mechanism to produce power from the generator.

The rapidly spinning shaft drives the generator to produce electric energy. Electricity from the generator goes to a transformer which converts it to the right voltage for the electricity grid. The electricity is then transmitted via the electricity network.
