Abstract
The choice of a wind turbine for a given site is a very significant operation. It is advised to make an in-depth study on the characteristics of the aerogenerator and the implantation site before any installation of a wind farm for choosing well the system best adapted to the energy needs. The objective of this study is to sensitize the users of the wind energy on the various problems involved in the aerogenerator installation on any site and to provide a decision-making aid to the judicious choice of the wind system best adapted. The idea is to estimate, for a selected implantation site, the energy production and the operating time of several wind systems. We can thus select the aerogenerator best adapted by making a compromise between a maximum recovery of energy and a high time of production. The influence height of the aerogenerator on energy profitability is also studied. We apply this step to the twenty six Tunisian synoptic sites by implantation scenarios of seven wind systems of various nominal speeds in function of the height.

Face to the environmental problems caused by the greenhouse gas emissions during exploitation of the conventional resources, other alternative energy resources were and must continue to be developed

Summary
Face to the environmental problems caused by the greenhouse gas emissions during exploitation of the conventional resources, other alternative energy resources were and must continue to be developed. We are mainly interested in the wind power which is regarded as a promising source in the improvement of the energy balance and the environmental preservation. The realization of a wind power station must take into account the wind resource. The study of the wind potential is a fundamental component of a wind project which determines the annual production and which allows the project manager to establish its business plan [1,2,3,4,5,6,7,8]. An error of a few percentages in the evaluation of the wind potential can have disastrous consequences on the future profitability of the project
