    摘要： The present invention concerns a method of detecting electric variables of a three-phase AC network having a first, a second and a third phase, including the steps of measuring a respective voltage value of the first, second and third phases in relation to a neutral conductor at a first moment in time, transforming the three voltage values of the first moment in time into polar co-ordinates with a voltage amplitude and a phase angle, repeating measurement and transformation for at least one further moment in time, and determining the currently prevailing frequency, voltage amplitude and/or phase angle of at least one of the phases from the voltage values transformed into polar co-ordinates.

    摘要： The present invention concerns a method of controlling a wind power installation connected to an electric network having a generator with an aerodynamic rotor with an adjustable rotary speed, in which the wind power installation can be operated at an operating point which is optimum in relation to prevailing wind conditions at an optimum rotary speed, wherein the wind power installation is operated for a transitional period of time or lastingly at a non-optimum operating point at a non-optimum rotary speed and the non-optimum rotary speed is higher than the optimum rotary speed.
