Modeling the wind energy potential and selecting the most productive wind turbines at the Telico site - Mamou, Republic of Guinea

Abstract

This work concerns the modeling of the wind potential of the site of Télico-Mamou. This research allowed us to determine the wind roses during the two seasons and to choose the most adapted wind for the site of Télico. Thus, during the dry season the wind blows from the North-East and the rainy season comes from the South-West. The analysis of the wind data during the 30 years shows that the wind speed from 1981 is higher than 2m/s, except for the years 1990 to 1998 and 2006 to 2008. Thus, the Weibull distribution showed that the wind potential during the dry season (24W/m² K=2.66 A=3.3m/s and Vmoy = 2.98 at 20m) is higher than the wind potential during the rainy season (11W/m² K=2.88 A=2.6 and Vmoy = 2.36m/s at 20m).  We used two methods to select the appropriate wind turbine for the site, namely: the method of calculating the power output of a wind turbine and the method using RETScreen. The results all showed that the adapted high power (S.64/1000) and low power (STE/500W) wind turbines correspond to those with lower starting and rated speeds.
