description The invention relates to a method for controlling a wind energy installation (100) having an aerodynamic rotor with rotor blades, the blade angle of which can be adjusted, comprising the steps of operating the wind energy installation in a partial load range with a rotor speed below a nominal speed and with an output power below a nominal power, using a speed/power characteristic curve which indicates a relationship between a rotor speed established on the basis of the prevailing wind and an output power to be set for this purpose or using a speed/torque characteristic curve which indicates a relationship between a rotor speed established on the basis of the prevailing wind and a torque to be set for this purpose, setting an output power according to the speed/power characteristic curve or a torque according to the speed/torque characteristic curve, wherein the speed/power characteristic curve or the speed/torque characteristic curve has a hysteresis region in the region of a problem speed to be avoided.
