In this research, a study of solution to the problems of transmission in wind turbines, where the electronic appliances and gearboxes components responsible for much of the wind turbine problems as they increase the cost of operation and maintenance of wind turbines and here comes the role of variable transport systems ratios, which is a solution more efficient than in fixed proportions regimes where create a dynamic model of the turbine wind using the aerodynamic properties of the blade wind and calculate torque when the wind changing speeds values and this for each of the wind turbine with proportions variable order and fixed ratio using MATLAB software and after study shows that energy production is slightly higher and more importantly, so it is possible to say that the CVT system is a candidate to be the subject of research for future developments of the technology of wind turbines.
