Abstract
A method for determining a target exhaust temperature for a gas turbine including: determining a target exhaust temperature based on a compressor pressure condition; determining a temperature adjustment to the target exhaust temperature based on at least one parameter of a group of parameters consisting of specific humidity, compressor inlet pressure loss and turbine exhaust back pressure; and adjusting the target exhaust temperature by applying the temperature adjustment.

A method for determining a target exhaust temperature for a gas turbine comprising:
- a. determining a target exhaust temperature based on a compressor pressure condition;
- b. determining a temperature adjustment to the target exhaust temperature based on at least one parameter of a group of parameters consisting of specific humidity, compressor inlet pressure loss and turbine exhaust back pressure;
- and
- c. adjusting the target exhaust temperature by applying the temperature adjustment.
A method for determining a target exhaust temperature for a gas turbine comprising:
- a. determining a target turbine exhaust temperature based on a compressor schedule having as an input compressor pressure ratio and as an output target turbine exhaust;
- b. adjusting the output target turbine exhaust temperature to compensate for a load condition of the gas turbine;
- c. determining a temperature change to be applied to the output target turbine exhaust temperature wherein the temperature change is derived from at least one parameter of a group of parameters consisting of specific humidity, compressor inlet pressure loss and turbine exhaust back pressure;
- d. changing the target exhaust temperature by the temperature change, and
- e. controlling the gas turbine based on the changed target exhaust temperature.
