<p><P>PROBLEM TO BE SOLVED: To provide a method for controlling gas turbine combustors, performing output control according to a planned value by eliminating the influence of variation in the temperature distribution of exhaust gas temperature measurements due to a change in a premixed fuel ratio. <P>SOLUTION: The method for controlling the gas turbine combustors in a premixed combustion type power generation gas turbine includes: a procedure of checking and setting an optimum value and a range of a premixed fuel ratio which is the ratio of fuel required for premixed combustion to entire fuel, in a gas turbine verification run in a periodical inspection and/or test operation; a procedure of inputting and setting a deviation characteristic of exhaust gas temperature corresponding to the change in the premixed fuel ratio; a procedure of calculating an exhaust-gas-temperature correction value corresponding to an optimum value of the premixed fuel ratio set based on the deviation characteristic of exhaust gas temperature: a procedure of calculating a corrected exhaust gas temperature from the exhaust-gas-temperature correction value and a detection value of exhaust gas temperature at the operation, and a procedure of calculating a command value of a fuel-flow-control-valve opening degree based on the corrected exhaust gas temperature. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
