TORSIONAL VIBRATION RESPONSE OF SHAFT SYSTEM OF DONGFANG 200MW TURBINE-GENERATORS CAUSED BY STEAM EXCITATION UNDER LOAD REJECTION AND FAST VALVING
A mathematical model for the governing system and a lumped model for the mechanical system of steam turbine are introduced. These models are mainly used to deal with the torsionai vibration response of shaft system when the governing valve is fast activated and the changes of the maximum torsionai vibration stress on each section of shaft system when the unit goes through fast valving. They are really useful to further study of the torsionai vibration of large-capacity units.
