US 10,309,320 B2 · Method for regulating a gas turbine

Abstract

A method for regulating a gas turbine wherein the fuel quantity supplied to the burners of the gas turbine is regulated using a target value for the corrected turbine outlet temperature. A stable operation of the gas turbine is to be allowed with a particularly high degree of efficiency and a high output at the same time. The target value for the corrected turbine outlet temperature is set using a value which characterizes the combustion stability in the burners, wherein the target value for the corrected turbine outlet temperature is set additionally using the surrounding temperature. Furthermore, the target value for the corrected turbine outlet temperature is set only below a specified surrounding temperature using the value which characterizes the combustion stability in the burners.

A method for regulating a gas turbine, the method comprising:

determining a corrected turbine outlet temperature as a function of a measured ambient temperature,
determining, only when the measured ambient temperature is less than a predefined ambient temperature, a target temperature for the corrected turbine outlet temperature by using a value which is characteristic of the combustion stability in burners of the gas turbine and the measured ambient temperature;
and
regulating a fuel quantity supplied to the burners of the gas turbine based on the target temperature, wherein when the corrected turbine outlet temperature is less than the target temperature, increasing the fuel quantity supplied to the burners of the gas turbine, wherein when the corrected turbine outlet temperature is greater than the target temperature, decreasing the fuel quantity supplied to the burners of the gas turbine.
