Method of operating an integrated solar combined cycle power plant and solar combined cycle power plant for carrying out the method

摘要

The method involves supplying a water/steam circuit (20) with heat from a solar array (33), where the water/steam circuit is designed only for a full load on a sequential combustion gas turbine (11). The load on the gas turbine is reduced when feeding additional power from the solar array into the water/steam circuit on the basis of the power additionally fed in from the solar array to such an extent that total output power of an integrated solar combined-cycle power station remains constant. An independent claim is also included for an integrated solar combined-cycle power station comprising a water/steam circuit.
