Abstract
The present disclosure relates to a method for controlling a wind turbine of the type including a rotor, a generator, a frequency converter, a control unit and means for connecting to a wind farm grid, using means for receiving a local voltage reference value (V) and a regulator () which calculates the reactive power to be generated (Q) as a function of the voltage error (ΔV), such that it can be operated over the entire voltage range. The system also includes: at least one saturator element () in which the reactive power to be generated is limited, whereby the limits (Q, Q, QMAX, Q, Q, Q) are calculated dynamically as a function of the voltage, this block outputting a reference reactive power of the wind turbine (Q, Q, Q); and an element () for calculating the actual limit of the active power (P) as a function of the pre-limited reactive power (Q, Q) and the apparent power available at that moment.
