This paper gives a description of a wind generator system composed by a doubly fed induction generator (DFIG), its dynamic model and each one of its subsystems. Also, the control logic that regulates the active and reactive power delivered by the DFIG is described. The electrical control logic is based on stator flux oriented technique and the turbine speed is controlled varying the blade pitch angle. The three regulators found had been designed using the frequency domain approach based on genetic algorithms.
