【Abstract】 The torsional vibration behaviour of turbogenerator shafts with SSR occurring in the power system is researched. A model including mechanical and electrical parameters is developed and simulated on a computer. By making use of a dynamic model unit and an analogue network, a number of experiments of SSR torsional vibration are carried out. Research results show that the impacts of SSR on turbogenerator shafts are closely related to the behaviour and operation parameters of the unit.更多还原
