摘　　要：本文通过对大坝电厂３００ＭＷ汽轮发电机组在有无快关的发电机端三相短路的四种工况下的轴系扭振固有特性及响应的计算，论证了机组轴系扭振的安全性及实施快关的可行性，为机组的安全运行、实施快关技术提供了理论依据。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.
