摘要：Mechanical parameters are determined for a set of turbines and power generator of 1000 MW of the reference power unit operated at super-critical parameters.The modal method is used to calculate the frequencies of intrinsic vibrations of the vibrating systems.The paper investigates the values of torqu moments which may occur in the sections of shafts upon disturbances in the electrical power system,e.g.near faults,action of automatic reclosing systems,synchronisation or interaction of electromagnetic moments from the grid side which introduce the system into resonance vibration.
