Title:
GAS TURBINE CONTROL DEVICE, GAS TURBINE CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/218930
Kind Code:
A1
Abstract:
This gas turbine control device comprises: a fuel flow rate calculation unit that calculates a fuel flow rate indicating an amount of fuel entering a combustor; an air flow rate calculation unit that calculates an air flow rate indicating an amount of air taken in by the combustor; a turbine entrance temperature calculation unit that calculates a turbine entrance temperature, on the basis of the fuel flow rate, the air flow rate, and a physical model formula for thermal energy balance about the combustor; a heat balance computation unit that performs computation to satisfy the heat balance of the gas turbine, on the basis of measurement data about the energy balance of the gas turbine, and outputs the computation result; a state detection unit that detects the state of the gas turbine; and a correction processing unit that, on the basis of the computation result output by the heat balance computation unit when the state of the gas turbine detected by the state detection unit is a static state, corrects one or both of the fuel flow rate and the air flow rate, and gives the corrected flow rate to the turbine entrance temperature calculation unit.
