Potencial eólico do Nordeste Brasileiro.

Abstract

The constant world population growth concerns, as it requires ever-increasing exploitation of natural and expansion of electricity production resources, so essential for maintaining proper living, industrial maintenance, services and trade. For this, it is necessary to develop new sources of energy, and the increasing worldwide concern is for renewable and clean energy sources. This paper presents a study on the wind potential of the Brazilian Northeast. Thus, it asks-as: the Brazilian Northeast has favorable wind characteristics for the installation of windfarms? The price of wind energy MWh is competitive with other energy sources in the Brazilian energy matrix? Thus, this study will provide a detailed analysis of the schemes of the winds in macro-scale, meso-scale and micro-scale, what factors determine their regime and properties, and which characteristics predominate in the Brazilian Northeast winds. It will be also done a detailed analysis of the components and sub-components of wind turbines, such as the transformation of wind energy into electricity is done and what control systems are used in wind turbines to extract the maximum power of the winds. Moreover, it will be an outline of the progress of wind energy in the world and Brazilian energy matrix, analysis of investments in relation to other energy sources. Finally, an outline of the wind potential of the Brazilian Northeast will be done by dividing the northeast region into sub-regions and analyzing the potential of these sub-regions taking into account the characteristics of meso-scale and micro-scale, analyzing the methods used to get the data in question. For this research we used the deductive method, through literature, historical and qualitative research in order to get the data envisaged in it. From the above, it could be determined that the Brazilian Northeast has a very favorable wind potential for the installation of windfarms in areas that do not have potential for conventional investments and you can observe the need for advanced anemometric stations in order to estimate more accurately the real potential Wind considering that the data used are from 2002 and have not used appropriate software to the specific characteristics of the Northeast.
