摘要： This power generation system is provided with a medium circuit, a circulation pump, an evaporator which evaporates a medium, an expander configured to be driven using the medium evaporated by the evaporator, a condenser configured to condense the medium discharged from the expander, a generator configured to be driven by the expander to generate power, a cooling system configured to cool the generator using the medium taken out from the medium circuit at a downstream side of the condenser, and a gas-liquid separator configured to separate the medium heated as a consequence of cooling the generator by the cooling system into gas and liquid phases, wherein the gas phase of the medium is flowed into the medium circuit at an upstream side of the condenser, and the liquid phase of the medium is flowed into the medium circuit at the downstream side of the condenser.

摘要： A power generation system includes a first on-off valve that, with respect to a maintenance target device including at least one of a circulation pump, an evaporator, an expander, and a condenser in a medium circuit through which a medium with a boiling point lower than that of water circulates, is on an upstream side in a flow direction of the medium in the medium circuit, and is capable of shutting off the flow of the medium; a second on-off valve that is on a downstream side in the flow direction of the medium in the medium circuit, and is capable of shutting off the flow of the medium; a port that is communicable with the medium circuit between the first on-off valve and the second on-off valve; and a third on-off valve that is in the port.
