The control method of a wind turbine generator increases the speed range of wind turbine generators, maximising the operation and efficiency thereof, in addition to lengthening their service life, on minimising the extreme and fatigue loads to which the wind turbine generators are subject, and which are due mainly to the stops and disconnections thereof as a result of strong gusts of wind. More specifically, the control method of the present invention stands out essentially for being based on the control of the reactive current circulating through the electric generator, said reactive current control being carried out in accordance with the rotational speed (omegag) for the purpose of reducing the voltage at the converter terminals on the generator side, or rotor voltage (VR), which ultimately allows a transitional increase in the speed range of the wind turbine generator.
