FIELD: engines and pumps.
SUBSTANCE: invention relates to turbomachine shafting slow barring. Proposed system comprises electrical generator, primary exciter and secondary exciter. In rated mode, auxiliary exciter is used as a permanently-excited synchronous machine for electric power generation. In slow barring mode, secondary exciter doubles as a slow barring motor. Note here that this system comprises the switch to selected rated mode and slow barring mode.
EFFECT: slow shifting barring with application of external oil hydromotor.
