摘要： A method is provided for operating a combined cycle power plant having at least one gas turbine, a heat recovery steam generator (HSRG), a steam turbine and a CO2 capture system. The method includes recirculating a first partial flow of flue gases from the HRSG. The method also includes capturing CO2 from a second partial flow of flue gases from the HRSG; and operating a supplementary firing to increase the net power output of the plant and to at least partly compensate the power consumption of the CO2 capture system. A combined cycle power plant is also provided. The plant includes at least one gas turbine, at least one heat recovery steam generator, at least one steam turbine at least one CO2 capture system, and flue gas recirculation. The plant also includes a low excess air supplementary firing.

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 power plant frequency response characteristic is implemented by controlling the power consumption of a CO2 capture and compression system. A power reserve is provided for under-frequency events without deloading the plant to part load, by an operating method, in which the power consumption of the CO2 capture system is used to control the net output of the plant.
