Abstract:
A method for controlling a steam turbine, the method which comprises:regulating a steam feed via a feed valve, and regulating a steam bleed via a bleed valve; supplying, with one of a first regulator and a second regulator, a first control signal and a second control signal to a regulating structure as a function of controlled variables fed to the one of the first regulator and the second regulator; linking, when there is a task-specific change between the first and second regulators, by using always a same regulating structure including a parameter set subdivided into subgroups, each subgroup having a first parameter and a second parameter, a result of a conversion of the first control signal with the second parameter and a result of a conversion of the second control signal with the first parameters to one another; determining a first actuating signal with a first one of the subgroups and determining a second actuating signal with a second one of the subgroups; and feeding the first actuating signal to the feed valve and feeding the second actuating signal to the bleed valve.
