A combustion control device is installed in a gas turbine including a compressor, a combustor, a turbine, a turbine bypass pipe through which compressed air from a casing is discharged to a turbine downstream part so as to bypass the turbine, and a turbine bypass valve that regulates a turbine bypass flow rate of the compressed air. The combustion control device includes: a fuel distribution setting unit that sets a turbine inlet temperature or a turbine inlet temperature-equivalent control variable on the basis of input data, and sets fuel distribution ratios on the basis of the turbine inlet temperature or the turbine inlet temperature-equivalent control variable; and a fuel valve opening setting section that sets the valve openings of fuel regulating valves. The fuel distribution setting unit includes correction means for modifying the fuel distribution ratios.

Gas turbine combustion control device and combustion control method and program therefor

A combustion control device () is installed in a gas turbine including a compressor (), combustors (), a turbine (), a bleed air pipe () through which bleed air is returned to an inlet of an air intake facility (), and an air bleed valve () that regulates the amount of bleed air extracted. The combustion control device () includes: a fuel distribution setting unit () that sets a turbine inlet temperature or a turbine inlet temperature-equivalent control variable on the basis of input data, and sets fuel distribution ratios on the basis of the turbine inlet temperature or the turbine inlet temperature-equivalent control variable; and a fuel valve opening setting section () that sets the valve openings of fuel regulating valves. The fuel distribution setting unit () includes correction means for modifying the fuel distribution ratios.
