  • Patent number: 9920746
    Abstract: The invention relates to a method for controlling a generator of electric energy that is connected to an electrical supply grid on a grid connection point, comprising the following steps: feeding electrical power into the electrical supply grid, whereby the generator is operated in a first operating point, interrupting the feeding so that no power is fed into the supply grid if a fault in the electrical supply grid or a fault of the feeding into the electrical supply grid exists or is displayed, resuming the feeding so that electrical power is again fed into the supply grid, whereby the generator resumes the feeding in a second operating point or is gradually increased in said second operating point, and the second operating point is designed in such a way that it feeds into the supply grid with a higher stability reserve than the first operating point.

  • Publication number: 20160032891
    Abstract: The invention relates to a wind turbine that comprises a rotor (106) having at least two rotor blades (108), an electrical generator that is directly or indirectly coupled to the rotor (106) of the wind turbine and said generator generates electrical power while the rotor (106) rotates, and a control unit (120) for controlling the operation of the wind turbine. The control unit (120) activates a first malfunction operating mode if parameters of a supply network exceed or fall below a threshold value. The control unit (120) is embodied in the first operating mode for the purpose of reducing the rotational speed of the rotor (106) to zero and for the purpose of activating a consumer (400) in order to consume, by means of the consumer (400), the electrical power that is generated in the malfunction operating mode by means of the generator.
