摘要： A method is provided for operating a power station (10) with turbine shafting (11) including a gas turbine (12) and a generator (18) that is driven directly by the gas turbine (12) and that generates alternating current with an operating frequency. The output of the generator is connected to an electrical grid (21) with a given grid frequency. An electronic decoupling apparatus or variable electronic gearbox (27) is arranged between the generator (18) and the grid (21). The decoupling apparatus decouples the operating frequency from the grid frequency. In the event of a temporary over-frequency or under-frequency event in the electrical grid (21), the mechanical rotational speed of the gas turbine (12) is decreased more than the grid frequency during an under-frequency event of the electrical grid (21) and is increased more than the grid frequency during an over-frequency event of the electrical grid (21).

摘要： A method is provided for operating a power station (10), with turbine shafting (11), that includes a gas turbine (12) and a generator (18) driven directly by the gas turbine (12) and that generates alternating current with an operating frequency, the output of the generator is connected with an electrical grid (21) with given grid frequency. An electronic decoupling apparatus or variable electronic gearbox (27) is arranged between the generator (18) and the grid (21), the decoupling apparatus decouples the operating frequency from the grid frequency. Increased service life of the station and reduced emissions are achieved in that, when there are longer-lasting changes in the grid frequency, the mechanical or aerodynamic rotational speed of the gas turbine (12) is kept constant and the output of the gas turbine (12) is adjusted without a delay.
