SYSTEM AND METHOD FOR PROTECTION OF GAS TURBINE HOT GAS PATH AND ROTOR PARTS FROM THERMAL DISTRESS

摘要

A system for operating a gas turbine includes a controller configured to: receive input from a plurality of sensors that sense parameters of the gas turbine during operation; run a first model of the operation of the gas turbine from one or more of the parameters; determine one or more unmeasured variables of the operation from the first model; run a second model of process variables from one or more of the sensed parameters and one or more of the unmeasured variables; determine differences between the process variables and associated boundaries; and adjust one or more effectors of the gas turbine to maintain a predetermined margin between the process variables and hardware physical limits.
