Modelling of rotor speed transient with rotor to stator contact
Résumé
A rotor-stator model of a turbogenerator has been developed to solve rotational velocity transients: to this end, the angular position of a beam cross section is considered as a variable, allowing for the angular deceleration due to rotor-to-stator friction to be calculated in a more realistic representation of the interaction. The equations of motion derived from an energetic formulation are highly nonlinear and require a specific time integration procedure. Calculations were run considering different types of diaphragms
