Abstract (EN): The development of power electronics, electrical drives and wind turbines has allowed at increasing power of wind systems. So, limitation of mechanical stress and power disturbances has pointed out to strong demand of variable speed systems. In wind generation systems it is required to decouple and control active and reactive power flow with high dynamics due to Mains requirements. Fast and accurate control is especially important when it is designed to operate the induction machine below synchronism rotational speed as generator. This paper presents a controller that can extract power from wind kinetic energy in a large speed range, sub and hyper synchronism speed. This is achieved through an accurate control of the active and reactive power flow. To feed doubly the induction machine allows at controlling its operation in all four quadrants of the plane decoupled speed and generated power.
