Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A method for regulating a gas turbine, in which the fuel quantity supplied to the burners of the gas turbine is regulated using a target value (Tsoll) for the corrected turbine outlet temperature (TATK), the method comprising: determining the target value (Tsoll) for the corrected turbine outlet temperature (TATK) using a value (W) which is characteristic of the combustion stability in the burners, determining the target value (Tsoll) for the corrected turbine outlet temperature (TATK) using the ambient temperature (TV 1 ), wherein the target value (Tsoll) for the corrected turbine outlet temperature (TATK) is determined only below a predefined ambient temperature (TV 1 ) using the value (W) which is characteristic of the combustion stability in the burners. 2 . The method as claimed in claim 1 , wherein a thermal-acoustic variable (a, p) is used during the determination of the value (W) which is characteristic of the combustion stability in the burners. 3 . The method as claimed in claim 1 , wherein an acceleration (a) and/or an alternating pressure amplitude (p) are used during the determination of the value (W) which is characteristic of the combustion stability in the burners. 4 . The method as claimed in claim 1 , wherein a limiting value for the value (W) which is characteristic of the combustion stability in the burners is predefined, and the target value (Tsoll) for the corrected turbine outlet temperature (TATK) is lowered when the limiting value is undershot. 5 . The method as claimed in claim 1 , wherein the target value (Tsoll) for the corrected turbine outlet temperature (TATK) is determined in the partial load mode using the value (W) which is characteristic of the combustion stability in the burners. 6 . A control unit for a gas turbine, in which the fuel quantity supplied to the burners of the gas turbine is regulated using a target value (Tsoll) for the corrected turbine outlet temperature (TATK), wherein the control unit is configured to carry out a method comprising: determining the target value (Tsoll) for the corrected turbine outlet temperature (TATK) using a value (W) which is characteristic of the combustion stability in the burners, determining the target value (Tsoll) for the corrected turbine outlet temperature (TATK) using the ambient temperature (TV 1 ), wherein the target value (Tsoll) for the corrected turbine outlet temperature (TATK) is determined only below a predefined ambient temperature (TV 1 ) using the value (W) which is characteristic of the combustion stability in the burners. 7 . A gas turbine comprising: the control unit as claimed in claim 6 . 8 . A power plant comprising: the gas turbine as claimed in claim 7 .
