Technology

The use of wind as a renewable energy involves the conversion of power contained in masses of moving air into rotating shaft power. The conversion process utilises aerodynamic forces (lift and/or drag) to produce a net positive turning moment on a shaft, resulting in the production of mechanical power which can be converted to electrical power.

The amount of wind power (P) harnessable at a particular site can be expressed as,

P=½ρAV³Cp Watts where

P = The density of air, kg/m3.
V = The wind speed in m/s.
A = Swept area of the blades through which the wind blows, in m2.
Cp = Efficiency of conversion

The wind speed therefore plays a vital role for energy generation as there is a non- liner (cubic) relationship between wind speed and available power.

The energy content in wind at different region varies with latitude, land - sea disposition, altitude and season. In India the factor which mostly governs the availability of wind energy at a particular site is its geographical location with respect to the monsoon wind. The availability of data on wind speed being a basic requirement for determining the feasiblity of wind power generation at any site and due to the highly uneven distribution of wind speed over the country, an assesment of the wind resource over different regions was undertaken before any plans of harnessing the wind energy were drawn for implementation.
