Abstract
An electric power generator system or a motor comprising a doubly-fed asynchronous generator or motor comprising a stator and a rotor, a transformer having a first winding and a second winding, the first winding having a first end and a second end; and wherein the stator and the transformer are connectable in series with an electric power distribution grid.
Claims8
An electric power generator system or motor comprising:
- a doubly-fed asynchronous generator or motor comprising a stator and a rotor;
- a transformer having a first winding and a second winding, said first winding having a first end and a second end;
- a first electric power converter having an input and an output;
- and
- a second electric power converter having an input and an output;
- wherein said stator and said transformer are connectable in series with an electric power distribution grid, said rotor is connected to said input of said first electric power converter, said output of said first electric power converter is connected to said second electric power converter via a direct current connection, and said output of said second electric power converter is connected to said second winding of said transformer.
