ABSTRACT:
A combined cycle power plant has a plurality of gas turbine units each having a gas turbine and a heat recovery boiler for generating steam from heat from exhaust gas from the gas turbine. The gas turbine of a first one of the gas turbine units is a steam-cooled gas turbine. Steam turbines are driven by steam from the heat recovery boilers. For start-up of the first gas turbine unit, cooling steam generated in a heat recovery boiler different from not being the heat recovery boiler of the first gas turbine unit is fed to the steam-cooled gas turbine to effect cooling thereof during at least part of the start-up operation of the first gas turbine unit.
