Disclosed is a method for operating a gas turbine () comprising a compressor (), which is equipped with variable inlet guide vanes () and receives at its inlet an inlet air flow, which has passed a temperature-affecting air inlet system (), a combustor (') and a turbine (&#x2032;). In a closed loop control scheme, a control variable indicative of the turbine outlet temperature (TAT) is generated, and the air inlet system () and/or the variable inlet guide vanes () are controlled in accordance with said control variable such that the turbine outlet temperature (TAT) is kept at or above a desired setting value (TAT).

Method for operating a combined cycle power plant and plant to carry out such a method

A method for operating a gas turbine plant utilizing sequential combustion is provided. The gas turbine plant includes a compressor for compressing inducted combustion air, a first combustion chamber for combustion of a first fuel by utilizing the compressed combustion air, with a first turbine which is connected downstream of the first combustion chamber, and a second combustion chamber for combustion of a second fuel by utilizing the gases which emerge from the first turbine, with a second turbine which is connected downstream of the second combustion chamber. The method provides quick running up with simultaneously low emissions and homogeneous distribution of the turbine inlet temperature is achieved by the second combustion chamber being completely shut down for achieving a low partial load mode of the gas turbine plant.

Method for operating a gas turbine plant

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.
