Statistical Analysis Of Wind Speed Data
Öz
Wind speed is the most important parameter in the design and study of wind energy conversion devices. The energy which is obtained from wind is directly proportional with the cubic power of the wind speed. As the wind speed increases, the cost of the wind energy is reduced. In many studies in literature, it is assumed that the probability distribution related to wind speeds can be described by Weibull distribution, and it is accepted so without any statistical examination. In this study, the theoretical distributions of wind potentials fit to Weibull distribution for five different topographic situations from Turkey Wind Atlas are investigated and reported.
