There is provided a turbine power generation system with a single casing configuration capable of easily executing the inhibition of an over-rotation speed. A turbine power generation system in an embodiment includes: a turbine including a turbine casing and a turbine rotor that rotates by a working medium to be introduced into the turbine casing; and a power generator including a power generator rotor connected to the turbine rotor, the power generator being caused to generate power by rotation of the power generator rotor caused by the rotation of the turbine rotor. The turbine casing of the turbine is single, and a moment of inertia of the power generator rotor is larger than a moment of inertia of the turbine rotor.

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.
