  • Arrangement with a synchronous generator and an asynchronous machine
    Patent number: 10622924
    Abstract: An arrangement with a synchronous generator for the conversion of mechanical power into electrical power, with a predetermined number of pole pairs, an asynchronous machine, with a pronounced rotor winding, which is mechanically coupled to a rotor of the synchronous generator and has a number of pole pairs at least 1 greater than the synchronous generator.
    Type: Grant

  • Method of determining a rotor displacement angle
    Patent number: 9594091
    Abstract: A method of determining a rotor displacement angle of a synchronous generator having a rotor and electrically connected to a power supply network uses at least one rotary speed measuring device. During a revolution of the rotor, in particular during each revolution of the rotor, the measuring device communicates at least one rotary speed signal to an evaluation unit. A frequency measuring device communicates a frequency signal to the evaluation unit for each period duration of a voltage signal of the power supply network. A time duration between communication of the rotary speed signal and communication of the frequency signal is determined by the evaluation unit, and the rotor displacement angle is inferred in dependence on the determined time duration.
