TEMPERATURE BASED GAS TURBINE CONTROL AND METHOD

A method (100) for operating a gas turbine (10) at a desired gas turbine (10) production value. The method (100) includes setting a desired gas turbine (10) production value based on a schedule (250) of a reference gas turbine (10) shaft speed with respect to ambient temperature and an exhaust (22) temperature; comparing values of a gas turbine (10) shaft speed to the reference gas turbine (10) shaft speed to determine whether a difference between the gas turbine (10) shaft speed and the reference gas turbine (10) shaft speed is within or outside of a predetermined range; and in response to the difference being outside of the predetermined range, initiating a change in gas turbine (10) shaft speed to cause the gas turbine (10) to operate approximately at the desired gas turbine (10) production value.
