Systems and Methods for Modifying the Performance of a Gas Turbine

A system for modifying the operation and/or performance of a gas turbine comprising one or more combustors, the system comprising:

• at least one sensor for determining a gas exhaust temperature for the gas turbine;
• and
• a controller operable to:
• receive the gas exhaust temperature from the at least one sensor;
• estimate a transient heat transfer rate for the gas turbine based at least in part on the gas exhaust temperature;
• and
• control the one or more combustors based at least in part on the estimated transient heat transfer rate for the gas turbine.

A gas turbine system comprising:

• at least one gas turbine comprising at least one compressor, one or more combustors, a turbine, and an exhaust port;
• at least one sensor connected to the exhaust port;
• and
• at least one controller operable to
• receive the gas exhaust temperature from the sensor;
• estimate a heat transfer rate for the gas turbine based at least in part on the gas exhaust temperature;
• and
• control the one or more combustors based at least in part on the estimated transient heat transfer rate for the gas turbine.
