A combined cycle power generation facility of an embodiment includes a first heat recovery steam generator including a high-pressure steam generation part using an exhaust gas of a gas turbine and a reheat part; a high-pressure turbine to which steam is introduced from the high-pressure steam generation part; a combustor which combusts hydrogen and oxygen; a reheat steam pipe connecting the high-pressure turbine and the combustor with the reheat part interposed therebetween; an oxygen-hydrogen combustion turbine to which steam is introduced from the combustor; a second heat recovery steam generator including a steam generation part using an exhaust gas of the oxygen-hydrogen combustion turbine; a low-pressure turbine to which steam is introduced from the steam generation part; and a condenser which steam is introduced from the low-pressure turbine.

Combined cycle power generation facility

The invention provides a COturbine power generation system that can be easily prevented from reaching an overspeed condition. A COturbine power generation system of an embodiment includes a COmedium shutoff valve installed in a medium flow path between a regenerative heat exchanger and a combustor. When load rejection is to be performed, the COmedium shutoff valve closes to shut off the supply of the medium from the regenerative heat exchanger to the combustor.

Shaft stability is enhanced and reliability is improved. In a gas turbine power generation system of an embodiment, a pressurizing unit, a rotation control unit, a diaphragm coupling, a turbine, and a generator are disposed to line up sequentially on the same shaft. A thrust bearing is provided between the turbine and the generator. The turbine is configured such that a working medium flows from the diaphragm coupling side toward the rotation control unit side.
