Title:
FLOW RATIO CALCULATION DEVICE, CONTROL DEVICE PROVIDED WITH SAME, GAS TURBINE PLANT PROVIDED WITH SAID CONTROL DEVICE, FLOW RATIO CALCULATION METHOD, AND METHOD FOR CONTROLLING FUEL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/021298
Kind Code:
A1
Abstract:
 This flow ratio calculation device is provided with: a flow ratio calculator (141p) for using a predetermined relationship between a first parameter that can represent the combustion state in a combustor and the flow ratio of fuel flowing through a plurality of fuel systems, and determining a flow ratio corresponding to the value of the first parameter; a correction value calculator (142p) for determining a flow ratio correction value when the load of a gas turbine changes; a fluctuation sensor (144) for sensing fluctuations in a correlation value of the gas turbine load; and a corrector (151) for correcting the flow ratio determined by the flow ratio calculator (141p) using the correction value determined by the correction value calculator (142p) when a fluctuation of the load correlation value is sensed by the fluctuation sensor (144).
