TEMPERATURE BASED GAS TURBINE CONTROL AND METHOD

Abstract:

A method for operating a gas turbine at a desired gas turbine production value. The method includes setting a desired gas turbine production value based on a schedule of a reference gas turbine shaft speed with respect to ambient temperature and an exhaust temperature; comparing values of a gas turbine shaft speed to the reference gas turbine shaft speed to determine whether a difference between the gas turbine shaft speed and the reference gas turbine 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 shaft speed to cause the gas turbine to operate approximately at the desired gas turbine production value.
