Method and device for regulating the operating line of a gas turbine combustion chamber

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, and
• a 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.
