A regulating device for regulating the course of a gas turbine plant has at least one sensor for sensing a measurement variable and for outputting a measurement signal which represents the measurement variable; at least one adjusting system for influencing air and/or fuel supply to a combustion chamber of the gas turbine plant on the basis of a correcting variable; and a regulator connected to the at least one sensor so as to receive the measurement variable and to the at least one adjusting system for outputting the correcting variable, the regulator being designed to determine the correcting variable on the basis of the measurement variable received and its deviation from a pilot variable. At least one sensor is designed to sense the variation in time of at least one burner or combustion chamber parameter as measurement variable.

1. A regulating method for regulating the operating line of a gas turbine plant, comprising: capturing a controlled variable,comparing the captured controlled variable with a predetermined reference variable;determining a manipulated variable based on the comparison of the captured controlled variable with the reference variable, andoutputting the determined manipulated variable to an adjusting facility influencing an air and/or fuel supply to a combustion chamber with a controlled variable, that indicates an approach of a combustion flame to a stability limit, being used as the controlled variable,wherein the captured controlled variable is the change in an alternating pressure over time captured by a sensor disposed at a burner flange comprising a burner, wherein the burner flange is disposed on an outer housing that surrounds at least partially the combustion chamber, wherein the sensor extends through the burner flange, whereby a portion of the sensor faces a combustion chamber plenum. 2. The regulating method as claimed in claim 1, wherein in addition to the change in an alternating pressure at the burner flange, the controlled variable is selected from the group consisting of: a change in a combustion chamber acceleration over time, and a combustion parameter. 3. The regulating method as claimed in claim 2, wherein the combustion parameter is a NOx content of a combustion waste gas or a CO content of the combustion waste gas or a pressure drop across the combustion chamber. 4. The regulating method as claimed in claim 1, wherein an absolute value of a burner parameter or a combustion chamber parameter is captured as a further controlled variable. 5. The regulating method as claimed in claim 1, wherein a variable, which results in a change in gas turbine output, is output as a manipulated variable or a variable, which results in a change in the corrected temperature of the combustion waste gases, is output as a manipulated variable or a variable, which results in a change in a pilot gas mass flow, is output as a manipulated variable. 6. The regulating method as claimed in claim 1, wherein the comparison of a captured controlled variable with a reference variable and/orthe determination of the manipulated variable based on the comparison is/are effected by a fuzzy logic algorithm. 7. The regulating method as claimed in claim 1, wherein the comparison of a captured controlled variable with a reference variable and/orthe determination of the manipulated variable based on the comparison is/are effected by means of a neural network. 8. The regulating method as claimed in claim 1, wherein the comparison of a captured controlled variable with a reference variable and/orthe determination of the manipulated variable based on the comparison is/are effected by a comparison using a fixed rule system. 9. The regulating method as claimed in claim 1, wherein an oscillating variable is captured as the controlled variables that change over time. 10. The regulating method as claimed in claim 9, wherein the oscillating variable is subjected to a fast Fourier transformation and/or mean autocorrelation. 11. A regulating device for regulating the operating line of a gas turbine plant, comprising: a sensor module including at least a first sensor that captures a measurement variable and outputs a measurement signal representing the measurement variable;an adjusting facility that influences an air and/or fuel supply to a combustion chamber based on a manipulated variable, anda regulator connected to the sensor module that receives the measurement variable and the adjusting facility for outputting the manipulated variable, the regulator configured to determine the manipulated variable based on the received measurement variable and the deviation from a reference variable,wherein the first sensor is disposed at a burner flange comprising a burner, and is configured to capture the change in an alternating pressure over time at the burner flange, wherein the burner flange is disposed on an outer housing that surrounds at least partially the combustion chamber, wherein the first sensor extends through the burner flange, whereby a portion of the sensor faces a combustion chamber plenum. 12. The regulating device as claimed in claim 11, wherein the sensor module includes a second sensor that captures a combustion chamber acceleration. 13. The regulating device as claimed in claim 11, wherein an emission measuring device is connected to the regulator. 14. The regulating device as claimed in claim 11, wherein the sensor module includes a third sensor which is connected to the regulator for capturing an absolute value of a combustion chamber parameter. 15. The regulating device as claimed in claim 11, wherein a fuel valve that influences a fuel mass flow supplied for combustion in a combustion chamber or a compressor vane ring is the adjusting facility. 16. The regulating device as claimed in claim 11, wherein the regulator contains a regulating concept based on fuzzy logic, a neural network, or a fixed rule system. 17. The regulating device as claimed in claim 11, wherein the sensor module is configured to capture an oscillating measurement variable. 18. The regulating device as claimed in claim 17, further comprising a Fourier transformation unit configured to perform a fast Fourier transformation and/ora computation unit for determining mean autocorrelations.
