Wind characteristics of Algeria

摘要

The paper presents wind speed data analysis over a period of almost 10 years between 1977 and 1988 from three stations, namely Adrar, Timimoun and Tindouf. The long-term mean wind speed at these sites was 5.9, 5.1 and 4.3 m/s at 10 meters above ground level (AGL), respectively and registered every three hour interval at all the stations. Higher wind speeds were observed in the day time between 09:00 and 18:00 hours and relatively smaller during rest of the period. The data show also that the long-term seasonal wind speeds were found to be relatively higher during March to September compared to other months so which helps in planning the operation of existing power plants in coordination with the wind power, since that the energy could be harnessed for almost 64% the time using wind machines with cut-in-speed of 3 m/s or more.
