Caracteriza??o analítica e geométrica da metodologia geral de determina??o de distribui??es de Weibull para o regime eólico e suas aplica??es

摘要

The wind regime of a region can be described by frequency distributions that provide information and features extremely necessary for a possible deployment of wind systems of energy capturing in the region and the resulting applications in rural areas in remote regions. These features, such as the annual average speed, variance of speed and hourly average of wind power density, can be obtained by the frequency of occurrences of certain speed, which in turn should be studied through analytical expressions. The analytic function more suitable for wind distribution is the density function of Weibull, which can be determined by numerical methods and linear regression. The objective of this study is to characterize analytically and geometrically all methodological procedures necessary to carry out a full characterization of the wind regime of a region and its applications in Botucatu-SP to determine the energy potential for implementation of wind turbines. Thus it was possible to make statements of theorems related to how to characterize the wind regime, establishing a concise analytical methodology for defining the wind parameters of any region to be studied. For the development of this research, it was used a CAMPBELL anemometer.
