In this study, wind energy potential of Silchar, the Southern part of Assam, India was analyzed for the period of five years from 2003 - 2007. The wind velocity was recorded diurnally, which was averaged over 24 h in a day. The sampling was done after every 3 h. Diurnal wind speed variation shows the actual picture of wind regime of a place. The average wind velocity in Silchar is about 3.11 kmph, which is considerably low. The wind power density of the place was determined on monthly basis of the period from 2003 - 2007 and it showed that the average power density is found highest during the month of March to April, when it becomes around 40 watt/sq.m. The probabilities of observing various wind velocities were determined using Weibull and also Rayleigh’s distribution functions. The results between these two distributions were compared.
Key words: Weibull distribution, Rayleigh’s distribution, wind velocity, power density.
