Abstract

Wind speed is the most significant parameter for designing wind energy conversion system. In the present paper, statistical methods are used to analyze the wind speed data of the site Harshnath, situated in the Sikar district of the Indian state Rajasthan. Present analysis is carried out for two hub heights of 25 m and 65 m using Weibull distribution parameters based on monthly mean wind speed data of the selected location. From the analysis, it has been found that most probable wind speeds are 5.881 and 6.775 m/s and wind speed for maximum energy are 6.630 m/s and 7.439 m/s for considered hub heights respectively. The site has annual mean energy density of 110.006 kWh/m² and 160.430 kWh/m₂ at hub height of 25 m and 65 m respectively. Wind turbine model is also suggested based on capacity factor and annual mean energy output.
