Wind Power Plant
Among the replenish able source as an alternative to fossil
fuels, wind energy is also in equal race. The power generation on the large
scale using the wind as a source of energy is not yet so successful but it is
forecasted that the small wind power units will play a vital role in the
present condition of shortage. The development of village is one major phase of
the national development and this can be achieved through wind power.
The power
requirement for irrigation, lighting, small industrial units can be fulfilled
with the use of wind energy provided sufficient wind is available. The wind on
earth surface are caused primarily by the unequal heating of the land and the
water by the sun. The differences in temperature gradients induce the
circulation of air from one zone to another.
It has been estimated that roughly
10 million MWs of energy are continuously available in the earth’s winds. The
utilisation of some of this energy through various mechanical conversion
devices has played a decisive role in the economic development of many
countries where winds are strong and steady.
Windmills had been widely used in Persia, China, Europe and
the USA for pumping water and grinding grains. Efficient wind electric
generators were after developed in USA , thousands of which produced
electricity for farms and homes. A windmill converts the K.E. energy of moving
air mass into mechanical motion that can be either used directly to run the
machine or to turn the generator to produce electricity.
