Method for controlling a wind turbine

A method for controlling a wind turbine having a generator that is controlled via a converter where electrical power that is fed into an electrical transmission network is increased by a generative deceleration of the generator, the method comprising:

• inputting an actual value of rotational speed (nmeas) and a rotational speed setpoint (n*) into a control;
• outputting a set point value (N*) for a generator torque from the control;
• inputting the set point value (N*) for the generator torque into a limiter with a predefinable upper and lower limit (Nup, Nlow);
• and
• outputting a limited torque value (N*′), wherein the limited torque value (N*′) is applied to a control of a converter;
• increasing the actual value of the electrical power fed into an electrical transmission network (Pfreeze) by an additional amount of power Pinc in response to a boost signal (flagboost), wherein electrical power fed into an electrical transmission network (Pfreeze) and the additional amount of power Pinc are combined into an aggregated power setpoint value (PTotal);
• determining the set point value for a generator torque (N*boost) from the aggregated power setpoint value (PTotal);
• and
• applying the calculated set point value for the generator torque (N*boost) in the boost operation to the limiter both as the upper limit and as the lower limit.
