The wind energy market is constantly changing. For many years, the horizontal axis wind turbines occupy an important place in this market. Turbines operating at variable speed have important advantages in terms of energy production and the optimization of the extraction of wind energy.
The variable speed wind turbines, however, require a separate control to meet the quality standards for the delivered power. Usually the modification of the delivered power is perform by power electronics. The mechanical control approach is less expensive than approach by power electronics. The use of a continuously variable transmission (CVT) can be very advantageous.
The genetic algorithm (GA) developed in this study identifies the optimal configuration that can include a CVT. In addition of an hydrostatic transmission, the proposed configuration includes one three-stages, two single stage, one planetary gearbox and a SCIG constant speed generator. The behavior of the proposed system is analyzed with numerical simulation. The GA and the simulation then lead to an optimized system that meets the needs of the wind turbine industry. The proposed concept involves a lower cost while providing superior performances compared to concept generally used, without affecting the lifetime of the wind turbine.
