Abstract

A power generation system includes: a combustor operative to combust a fuel; a power generator operative to utilize energy obtained from the combustor when generating electric power; a fuel supplier operative to supply the fuel to the combustor; an air supplier operative to supply combustion air to the combustor; a discharged gas passage through which a discharged gas from the combustor flows; a CO detector operative to detect CO in the discharged gas; a temperature detector operative to detect a temperature of the discharged gas; and control circuitry operative to, when the discharged gas is flowing through the discharged gas passage, perform at least one of an operation of detecting a structural abnormality of the discharged gas passage based on a difference between detected temperatures of the temperature detector relative to a difference between heated amounts of the discharged gas heated by a heater and an operation of detecting the structural abnormality of the discharged gas passage based on the difference between the detected temperatures of the temperature detector relative to a difference between outputs of at least one of the fuel supplier and the air supplier.
