Patent ID: 7593803

Claim:
A method for adjusting a base fuel split schedule for a gas turbine combustor comprising: a. determining a corrected target turbine exhaust temperature based on a compressor pressure condition; b. determining a first corrected temperature adjustment to the corrected target exhaust temperature based on at least one parameter of a group of parameters consisting of compressor inlet pressure loss and turbine exhaust back pressure; c. determining a second corrected temperature adjustment to the corrected target exhaust temperature based on a nitrogen oxide (NOx) limiting requirement and the base fuel split command; d. determining an adjusted corrected target exhaust temperature based on the first corrected temperature adjustment and the second corrected temperature adjustment; e. determining an uncorrected adjusted target exhaust temperature based on a temperature of a discharge of a compressor of the gas turbine and the adjusted corrected target exhaust temperature; f. determining a temperature difference between the uncorrected adjusted target exhaust temperature and an uncorrected target exhaust temperature selected from a combustor temperature leveling algorithm, and g. applying the temperature difference to generate an adjusted fuel split schedule.
