Abstract

The results of evaluation of fatigue damage caused by the intense vibrations of steam turbine shafting at abnormal operation of turbine generator are presented. The abnormal operation of turbine generator may be caused by the sudden short-circuit in turbine generator or by the connection of turbine generator to the electric network. The evaluation of fatigue damage is based on the 3D finite element model of turbine shafting of steam turbine K-215-130. The fatigue properties of rotor steel were experimentally determined and used in the model. The fatigue damage of steam turbine shafting was evaluated for different scenarios of connection of turbine generator to the electric network and in account for experimentally determined damping properties of turbine shafting in operation.
