STROMAGGREGAT UND VERFAHREN ZUR ERZEUGUNG VON STROM EINER VORBESTIMMTEN NETZFREQUENZ

摘要

The generating unit has a drive turning a rotor (15) with variable rotational frequency (n). The rotor has a winding (17) which is designed for the generation of a rotating field linkage of the generator (11) with a rotating field frequency (f2) variable in relation to the rotor. A frequency transformer (19) is electrically connected to the rotor winding. From a control signal from a control unit (27) an electrical charging of the rotor winding is effected through the frequency transformer in such a way that with variable rotating field frequency a predetermined stator field frequency is produced. An independent claim is included for a device for the generating of a current of a predetermined mains frequency, especially by the aforesaid generating unit.
