Abstract
Interaction between the electrical transmission system and the turbine generator may induce torsional stresses to the shaft system whose magnitude and risk of damage have to be carefully analyzed in advance to ensure undisturbed operation and to preclude any damage from the unit. Within this task, the present paper investigates the torsional stressing which arise as a result of torsional resonance induced by pulsating components in the electrical torque of the generator and presents a method for assessing the susceptibility of natural torsional modes to excitation.Keywords
