Abstract (en)
[origin: EP3168434A1] A method of controlling a steam turbine comprises: defining a simplified model (M) of a rotor (5c) of a steam turbine in the form of a homogeneous and isotropic cylinder; determining a stress distribution in the rotor (5c) from parameters of the simplified model (M) and temperature values (ST) of steam (Q HP ) supplied to the steam turbine (5); comparing the stress determined in the rotor (5c) with a stress threshold (Ã TH ); and controlling the steam turbine (5) on the basis of a comparison between the stress determined in the rotor (5c) and the stress threshold (Ã TH ).
