There are many wind synoptic stations installed all over Iran. One of these stations in the coasts of Persian Gulf is Bardekhun station in Bushehr province. The goal of this study is to assess the wind energy potential of this region and to design a proper horizontal axis wind turbine for this site. The one-year measured hourly time-series wind speed data are extracted from measurements at a height of 10m, 30m and 40m above the ground level. The Weibull distribution gives the mean wind speed of 4.50 m/s, 5.36 m/s and 5.83 m/s and the power density per year of 125 W/m2, 196 W/m2 and 253 W/m2 respectively for these heights. According to these results, a small wind turbine can be installed in the height of 30m and 40m. A MATLAB code using the bladeelement-momentum theory has been developed to design and analyze the three-blade wind turbine rotor. After calculation of geometrical parameters of rotor blade, the rotor power coefficient versus rotor tip speed ratio is evaluated. The energy produced per year by this wind turbine using the Weibull distribution for wind speed will be 155MWh.
