Abstract

1. Method for output regulation in a power unit comprising a forced-through-flow steam generator (1), steam turbine (2) and generator (3), in which the electric generator outptut is adjusted by way of a control action (10) in the energy supply of the steam generator (1), and the steam pressure (pi ) before the turbine is adjustable by way of a control action (6) in the steam throughput of the turbine, in which a correstive signal, which is temporally decaying, derived from the manipulated variable of the output regulating circuit, influences the command variable (ps ) of the pressure regulating circuit, characterized in that the corrective signal is generated when, in a model-like electrical simulation (12, 13) of the controlled system "steam generator", a signal corresponding to the "steam generation behaviour" of the steam generator is subtractively combined with the actuating signal of the energy regulator and the difference signal is delayed corresponding to the store behaviour of the steam generator.
