SYSTEMS AND METHODS FOR ADAPTIVELY PREFILLING FUEL CIRCUITS

A method includes instructing a gas control valve of a gas turbine system to open, thereby prefilling a fuel circuit of the gas turbine system with fuel, wherein the fuel circuit is initially filled with purge gas. The method also includes generating a model of the gas turbine system that simulates...

Zusammenfassung:	A method includes instructing a gas control valve of a gas turbine system to open, thereby prefilling a fuel circuit of the gas turbine system with fuel, wherein the fuel circuit is initially filled with purge gas. The method also includes generating a model of the gas turbine system that simulates a modeled output of the gas turbine system based on a model input corresponding to a measured input to the gas turbine system. The method further includes receiving a measured output of the gas turbine system. The method also includes adjusting the model input such that the modeled output more closely matches the measured output when the measured output is not approximately equal to the modeled output. The method further includes instructing the gas control valve to open to prefill the fuel circuit during a subsequent prefill operation based at least in part on adjusting the model input.
