Variable speed wind turbine

A VARIABLE SPEED WIND TURBINE IS PRESENTED (10) CONTAINING A TURBINE ROTOR (12) THAT DRIVES AN AC INDUCTION GENERATOR (16 AND 18), AN ENERGY CONVERTER (20-34) THAT CONVERTS THE GENERATOR OUTPUT IN A FIXED-FREQUENCY AC POWER, A GENERATOR CONTROLLER (38 AND 40) AND AN INVERTER CONTROLLER (50 AND 52). THE GENERATOR CONTROLLER (38 AND 40) USES A FIELD ORIENTATION TO WELL REGULATE CURRENTS OR STATIC VOLTAGES TO CONTROL THE TORQUE REACTED BY THE GENERATOR. THE INVERTER CONTROLLER (50 AND 52) ADJUSTS THE OUTPUT CURRENTS TO SUPPLY A POLYPHASIC AC POWER, WITH ADVANCED OR DELAYED CURRENTS, AT AN ANGLE SPECIFIED BY A POWER FACTOR CONTROL SIGNAL.
