Performance evaluation of wind turbines for sites in Chad

For the production of electricity, the use of wind energy has become more interesting in recent years. In this present study, the authors assessed wind potential using wind speed data measured at 10 m altitude for a period of 18–30 years in Chad. The statistical method of Rayleigh's law was deployed in this study. In addition, the performance of five wind turbines in five different sites were examined based on their capacity factor and annual energy production. The results shows that the average monthly velocities of the five sites range from 2.54 m/s to 3.25 m/s and the power density varies from 20.80 W/m(2) to 44.17 W/m(2). By focusing on the annual energy production of these turbines, the results obtained show that the Enercom E-82 can be adapted for all the five sites.
