Abstract

PURPOSE: To make it possible to do driving a gas turbine at high efficiency, by precisely estimating a turbine inlet gas temperature from detected values of inlet temperature and pressure and outlet temperature and pressure in the compressor, turbine velocity, as well as fuel flow rate and controlling its operation on the basis of the thus-estimated gas temperature.
CONSTITUTION: Air compressed by a compressor 1 is burned with fuel from a fuel feeder 5 in a combustor 4, a turbine 7 is driven by its combustion gas. In this case, a turbine inlet gas temperature estimating device 18 is provided in a gas turbine controller 200. This estimating device 18 presumes inlet gas temperature from output signals of a compressor inlet air pressure detector 21, an inlet air temperature detector 22, a compressor discharged pressure detector 13, a discharged temperature detector 23, a fuel flow rate detector 24, and a turbine velocity detector 12. Output of the estimating device 18 is compared with output of a temperature setter 19, on the basis whose deviation, fuel demand signals are output through a low value selector 17 to a fuel controller 10.
