Characterisation of Wind Behaviour in Piauí in Order to Utilize Wind Energy
Abstract This work presents the characterization of wind behaviour in some regions of Piauí through analyses of daily and monthly average wind speed and average wind direction. The main objective of this work is identifying potential wind power sites using Windographer® software. Areas of Piauí such as: Valença, Floriano, Alvorada do Gurgueia, Oeiras, Caracol, São João do Piauí, Paulistana e Parnaíba were analysed through the 2010 database provided by The National Institute of Meteorology (INMET). This work provides, for each region, graphs of daily and yearly wind behaviour. The results show that Paulistana e Parnaíba present a satisfactory wind potential to generate electricity.
