Then I choose my wind tower’s length. L=50m. At this heigt the velocities change. So I calculate the new velocities of the site by using the following Formula; And the results from matlab is; v50 = …….m/s Columns 1 through 9 6.9913 7.2455 7.6269 8.8980 10.1692 9.6607 9.2794 10.1692 12.4572 Columns 10 through 18 11.5674 9.4065 6.8642 4.3219 6.4828 8.6438 7.4998 6.2286 8.8980 Columns 19 through 25 11.4403 10.1692 8.7709 9.5336 10.4234 12.2030 13.9826 1

After this step I calculate the frequencies and find V m with using MATLAB; vort = 9.6457 m/s The next step is calculating the standart daviation by using following Formula The result from MATLAB is; sigma = 2.2265 To calculate probability distribution, I use Rayleigh distribution The results of Rayleigh is Re = Columns 1 through 9 0.0781 0.0785 0.0788 0.0770 0.0717 0.0742 0.0757 0.0717 0.0567 Columns 10 through 18 0.0631 0.0752 0.0779 0.0623 0.0768 0.0777 0.0788 0.0758 0.0770 Columns 19 through 25 0.0640 0.0717 0.0774 0.0747 0.0703 0.0586 0.0453 2

From this graph ; Formula of power is; d = 31 m (From Matlab with rounding) Then I calculate omega; omega = 3.7935 rad/s omega1 = 36.2257 rev/min I choose V cutin =3,5 m/s and V cutout =15m/s Then I calculate power generated from the turbine by using MATLAB and plot it 4

Finally I calculate the Capacity Factor by using this Formula From Matlab Et3 = 4.1060e+006 Wh Cf = 0.6570 MATLAB code which is produced by me is; clear all 5
