Title: FUEL CONTROL DEVICE, COMBUSTOR, GAS TURBINE, FUEL CONTROL METHOD, AND PROGRAM
Abstract:
A fuel control device equipped with a trunk fuel valve degree-of-opening determination unit, a branch line flow rate determination unit, and a correction amount determination unit. The trunk fuel valve degree-of-opening determination unit determines the degree of opening of a flow rate adjustment valve of a trunk fuel supply line, which is the source of multiple branch lines, on the basis of a fuel control signal command based on the output of a gas turbine. The branch line flow rate determination unit determines the degree of opening of the flow rate adjustment valves of each branch line on the basis of the operating condition of the gas turbine. The correction amount determination unit determines a correction value for the degree of opening of the flow rate adjustment valves of the branch lines on the basis of a value for the differential pressure between the upstream fuel pressure for the respective nozzles connected to each branch line and the pressure when a correction is made to the outlet fuel pressure.
