摘      要：The shafting vibration is closely related to the rotational angular *** angular speed of hydro turbine generating sets(HTGS)is rapidly change in fault transient,it maybe reduce the shafting *** means of energy analysis,the differential equation of shafting vibration for the HTGS is derived,in which include the equation of generator rotor and hydro turbine runner,it can be applied to transient *** model is transformed into first order differential equation groups,and is combined with the motion equation of HTGS to build integrated *** additional forces of shafting are taken as input inspire in proposed model,the generality of model is *** last,the shafting vibration in emergency stop transient is simulated.
