Turbine power generation system

Abstract

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.

Dependencies are inferred from the claim text.
