Zusammenfassung:	According to one embodiment, there is provided a generator excitation apparatus including a plurality of first power converters (3) and a second power converter (4). The plurality of first power converters (3) are electrically connected to windings of respective phases of rotors of a wound rotor type induction generator (2) in which the windings of the rotors of the respective phases are electrically independent, and are configured to bidirectionally convert DC and AC. The second power converter (4) is configured to bidirectionally convert DC and AC between DC sides of the first power converters (3) and a three-phase DOC power supply (1). The DC sides of the first power converters (3) are electrically connected together to a DC side of the second power converter (4).
