Claim Text:
1. A method for automatic closed-loop control of one or more combustion temperatures in a gas turbine installation, comprising: measuring a plurality of temperatures of a working fluid of the gas turbine installation at various positions in the gas turbine installation; measuring a plurality of pressures of the working fluid at different positions in the gas turbine installation; determining a water content of the working fluid flowing through the gas turbine using an indirect method based on turbine inlet pressure measurements to deduce the water content of the working fluid flowing through the turbine installation as a function of the temperatures and pressures measured at different respective locations in the gas turbine installation; and setting of the one or more combustion temperatures for the gas turbine installation as a function of the determined water content, wherein a closed-loop control structure is defined for closed-loop control of the one or more combustion temperatures T where x
