摘要： Methods, systems, and program products for improved accuracy in estimating a combustion reference temperature (CRT) are provided. In one embodiment, the invention provides a method of estimating a combustion reference temperature (CRT) in a gas turbine, the method comprising: obtaining a measurement of at least one dynamic operating condition of the gas turbine selected from a group consisting of: an ambient condition, a compressor condition, a fuel condition, and a turbine condition; inputting a measurement of the at least one operating condition into a physics-based model; calculating at least one estimated internal state for the gas turbine using the physics-based model; and calculating an estimated CRT based on the at least one gas turbine internal state.

摘要： A coordinated air-fuel controller and associated method provide a fuel controller, a combustion air controller and a steady-state air versus fuel model. The fuel controller generates a fuel control output signal and the combustion air controller generates a combustion air control output signal. The fuel controller determines a preliminary fuel control signal based on at least one of first and second loop control signals, and determines the fuel control output signal based on the preliminary fuel control signal. The steady-state air versus fuel model processes the preliminary fuel control signal to determine an expected steady-state combustion air control signal. The combustion air controller determines a preliminary combustion air control signal based on at least one of a third loop control signal and a fourth loop control signal, and determines the combustion air control output signal based on the preliminary combustion air control signal and the expected steady-state combustion air control signal.
