FUEL CONTROL DEVICE, COMBUSTOR, GAS TURBINE, CONTROL METHOD, AND PROGRAM

摘要

A fuel control device is provided with: a combustion temperature estimated value calculator for using atmospheric conditions, an opening degree command value of a valve for controlling the amount of air mixed and combusted with fuel, and an output prediction value calculated on the basis of a fuel control signal command value used to calculate the total amount of fuel flowing to a plurality of fuel supply systems, to calculate a temperature estimated value when a mixture of fuel and incoming air is combusted; a fuel distribution command value calculator for calculating and outputting a fuel distribution command value indicating the distribution of fuel outputted from the plurality of fuel supply systems on the basis of the temperature estimated value; and a valve opening degree calculator for calculating the opening degrees of fuel flow rate adjustment valves of the plurality of fuel supply systems on the basis of the total amount of fuel, which is based on the fuel distribution command value and the fuel control signal command value.
