摘要： A method is provided for operating a gas turbine in a power station in which limits of the operating concept, which provide limits for optimization of the power station operation in respect of efficiency, service life consumption, emissions and power provision to the grid system, are adapted during operation. In particular, temperature limits and compressor inlet guide vane position limits are varied as a function of the optimization aims. A gas turbine power station is also provided for carrying out the method.

摘要： A method is provided for CO2 separation from a combined-cycle power plant with exhaust-gas recirculation and CO2 separation. The hot-gas flow is split into a recirculation flow and an exhaust-gas flow before the final turbine stage in the turbine. A first partial flow remains in the turbine and carries out expansion work in the conventional form, before its waste heat is dissipated, for example in a waste-heat boiler, and the gases are recirculated into the inlet flow of the gas turbine. A second partial flow is diverted before the final turbine stage, and emits its waste heat in an HRSG/heat exchanger, before CO2 is separated from the exhaust-gas flow at an increased pressure level.

摘要： CO2 compression is a main step in carbon capture and storage, which is essential to control global warming. CO2 compressors are powered by electric motors, which increase operational flexibility but require much energy leading to additional expenses, power and efficiency losses. A method is provided for optimized operation of a plant including a power generation unit with a CO2 capture system and compressor with minimum losses during normal operation, allowing flexible part load. The method allows steam from the power unit to drive a steam turbine, which drives the CO2 compressor via an engaged overrunning clutch if a sufficient amount of steam is available from the power unit, and to drive it by the generator, which is used as motor when insufficient steam is available from the power unit. When no or insufficient steam is available the clutch is disengaged and the steam turbine may be at standstill or idling.

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).

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.

摘要： An exemplary system method for the operation of a CCP P with flue gas recirculation to reduce NOx emissions and/or to increase the CO2 concentration in the flue gases to facilitate CO2 capture from the flue gases is disclosed. The flue gas recirculation rate (rFRG) is controlled as function of the combustion pressure and/or the hot gas temperature. Operability is enhanced by admixing of oxygen or oxygen enriched air to the gas turbine inlet gases or to the combustion.
