ABSTRACT:
The invention relates to a method for determination of a temperature, mass-averaged over a flow cross-section, of a gas flow in a gas turbine or the like, particularly during partial load operation of the gas turbine. The invention also relates to a control apparatus, which can be operated using the method according to the invention, for controlling a gas turbine installation.The method according to the invention comprising the steps of the temperature value of the gas flow being detected by a sensor or sensors at at least one position in the gas flow in the area of the flow cross-section, of determination of a correction value for correction of the temperature value for compensation for non-uniformities in the temperature profile of the gas flow across the flow cross-section as a function of at least one operating-point-specific parameter, and of correcting the temperature value, which is recorded by a sensor or sensors, by the correction value.
