A method is provided for operating a gas turbine plant including a compressor, which on an inlet side inducts intake air and compresses it, providing compressor exit air on a discharge side. The plant also includes a combustion chamber where fuel is combusted, using compressor exit air, forming a hot gas; and a turbine, where the hot gas is expanded, performing work. The method includes extracting compressed air from the compressor, directing it as cooling air flow into the combustion chamber and/or into the turbine for cooling thermally loaded components. The method also includes controlling at least one cooling air flow, for achieving specific operating targets, using a control element depending on an operating target. A gas turbine plant is also provided having at least one control element for cooling air flow control, and a gas turbine controller which controls the gas turbine plant based on selectable control parameter sets.
A method for operating a gas turbine plant, comprising a compressor, which on an inlet side inducts intake air through variable inlet guide vanes and compresses it for providing compressor exit air on a discharge side, a combustion chamber, in which a fuel is combusted, using the compressor exit air, forming a hot gas, and a turbine, in which the hot gas is expanded, performing work, the method comprising:
A gas turbine plant comprising a compressor, which on an inlet side inducts intake air through variable inlet guide vanes and compresses it for providing compressor exit air on a discharge side, a combustion chamber, in which a fuel is combusted, using the compressor exit air, forming hot gas, a turbine, in which the hot gas is expanded, performing work, wherein for cooling thermally loaded components of the combustion chamber and/or of the turbine a cooling air flow is directed from the compressor and/or from the exit of the compressor to the thermally loaded components, and at least one control element for controlling the cooling air flow, and a gas turbine controller, in which the control parameters for realizing a conventional operating concept are stored, and at least one additional set of control parameters, which is selected by an operator for realizing a specific operating concept, is stored in the gas turbine controller;
