Abstract
In a method of setting a main controlled variable during the operation of a gas-turbine group, the gas-turbine group essentially comprises a compressor (40), at least one combustion chamber (43), at least one turbine (41) and a generator (46). A desired value (3) is compared with a measured value (4) and the resulting main control difference (5) is hierarchically allocated via a management unit (1) to at least one cascade (9, 18). The cascade (9, 18) is essentially composed of a main-controlled-variable controller (6, 15) and a downstream variable controller (8, 17) which acts on the respective variable actuator (14, 23).
