【Abstract】 Abstract Safety against torsional vibration of Daba Power Station’s 300MW turbine-generator rotor and the feasibility of fast-valving are demonstrated throughcalculation of the natural torsional vibration characterestics and responses under four modes of three phase short circuiting at the generator’terminal whitand without fastvalving.This provides a theoretical basis for the unit’s safeoperation and implementation of fast-valving technique.更多还原
