The objective of this work is to evaluate the wind resource on the site of Adrar in southern Algeria. The hourly data used in this study span a period of 5 years. The considered parameters are the speed and direction of wind. For this purpose, the most energetic and frequent speed as well as the Weibull parameters to plot the wind rose were evaluated. Treatment focuses on coverage, the average monthly rate, annual average speed and average speeds by sector and their frequencies, to optimize site selection for future wind farm. The southern site "Adrar" is favorable for large ZWD (zone of wind development), why it was decided to investigate the possibility to set up a wind farm of 9 MW consisting of twelve wind turbines VERGNET GEV HP with nominal power of 800 KW. Next, the noise was calculated and modeled. The obtained results are k = 2.06 and C = 7.4 m/s for the Weibull parameters at ten meters above the ground with an average wind speed of 6.5 m/s. Our simulation of the noise propagation for the wind farm shows that noise level is estimated around 38 dB (A) at a distance of 220 m from the nearest turbine. We can conclude that these noise levels have no effect on health and comply with the Algerian standard.
