{This paper will provide an effective help to all those who make decisions regarding the planning and implementation of projects wind Energies. We used the software Alwin for sizing a wind farm of 140 MW installed in Melloussa cite, 25 Km from Tangier, in north Morocco . We analyzed the collected wind data during one year, to assess wind power potential, the prediction of produced electric power in the site based on a judicious choice of Wind Turbine Generator, as well as, the automatic determination of direction of the wind on the site and analysis of wind turbulence. Thus, the integration into the grid provides several benefits. However, this type of production which has an impact on the electric network and its connection is subject to technical constraints. We will study the various generators used to produce electric power from wind energy and choose the one with a good price per kilowatt hour, then to study the feasibility of integration of this wind farm in the electric grid. And finally, we treated the various principles, concepts used in data transmission and remote monitoring of wind farms, and we proposed industrial solutions of telemanagement which can be applied in remote wind farm in the site},
