Abstract

limrr maxlimThe invention relates to a method for operating a wind turbine (10) comprising a rotor (12) and a generator (18) connected to said rotor (12) for emitting electrical power to an electrical grid said rotor (12) comprising rotor blades (14) whose blade pitch angles (a) can be moved during operation in order to control the rotational speed (n) of the rotor (12). Upon reaching a rotational speed (n) higher than a rotational speed limit (n) that delimits an operational range (34 34 34 ) of said wind turbine (10) the rotor (12) is forcibly braked by increasing the blade pitch angle (a) with a predefined positive blade pitch angle movement rate (?) particularly with a maximum potential positive blade pitch angle movement rate (?). According to the invention the rotational speed limit (n) is altered as a function of a blade pitch angle movement rate (?) set by the control. The invention also relates to a corresponding wind turbine (10).
