Abstract: It is proposed that, during the operation of a steam turbine of a steam power plant, the internal pressure and also the internal temperature and, in the region outside it, the external temperature be determined in at least one steam-carrying component. As a result of a change in the operating state, in particular in the event of a load change, then, the abovementioned values vary, so that, under some circumstances, the mechanical stresses which in this case act on the steam-carrying component become unacceptably high. Consequently, a spatial temperature distribution and a reference stress of the steam-carrying component are determined from the abovementioned values and compared with a material limit stress. If the reference stress is greater than the material limit stress, a limit steam pressure desired value is determined, and at least one steam valve is set in such a way that the steam pressure on the steam-carrying component corresponds approximately to this limit steam pressure desired value.
