Abstract

A method for operating a steam turbine where steam turbine has at least two sub-turbines, wherein the steam turbine is paired with a steam turbine controller which has a sub-turbine controller for each of the sub-turbines, and each sub-turbine controller compares respective target values with respective actual values of the respective sub-turbine during operation in order to determine a respective control deviation for each sub-turbine.
