Identificação do potencial eólico para micro e minigeração para o estado do Paraná

Abstract

The transition between the current economic model, based on fossil fuel energy sources, and a sustainable model, supported by renewable energy sources, has become more important today. In this scenario, the Brazilian energy matrix is evidenced mainly because of hydroelectricity, however, several issues have been preventing its expansion. In this context, alternative sources represent a possible solution to complement the electricity supply. Considering the importance of this context, the research project aims to generate a mapping of the wind potential for the micro and minigeneration to the mesoregions of the state of Paraná as a way to technically base decisions of different relevance for possible implantation of small wind farms in the state. The analysis of the wind power potential of the state of Paraná was carried out from the data of 24 meteorological stations obtained by the Meteorological Database for Teaching and Research (BDMEP), which is managed by the National Institute of Meteorology (INMET), the data was showed with an interval corresponding to 1 hour from the period from 2003 to June 2016. With these data it was possible to identify the predominance of winds in the state, the maximum speed and the average speed, besides the generation of thematic maps presenting the wind potential for two types of wind turbines made using the QGis 2.16 software. The results showed that there is a predominance of East (E) winds for most of the state of Paraná, being the second direction of greatest occurrence South (S), followed by Northeast (NE). It was verified that there was a dominance of higher values of average and maximum velocity in the months of September, November, October and August, corresponding to the end of winter, spring and early summer and for data of wind potential, both for microgeneration and for minigeration it was possible to prove that for the state of Paraná, most of the months did not show great variation in relation to the power values found, however, some mesoregions presented potentials to be explored.
