摘要： A control system and methodology for a gas turbine having multiple fuel valves for multiple combustion chambers involves tuning the fuel values to associated combustion chambers to optimize nitrous oxide emissions; dynamic pressure, and variation in fuel/air ratio. Further, fine tuning of the fuel values is then used to maintain dynamic pressure oscillations, nitrous oxide emissions or variation in fuel/air ratio within predetermined limits.

摘要： A fault detection and isolation system for detecting leaks and blockages in a fluid handling system having at least one component through which fluid flows includes sensors for measuring fluid conditions upstream and downstream of the component. The sensors generate signals that are representative of the upstream and downstream fluid conditions and are fed to a control algorithm. The control algorithm uses the measured fluid conditions to generate estimates of an inlet state for the component and an outlet state for the component. The control algorithm also calculates innovation sequences for the estimated inlet and outlet states, and then compares the innovation sequences to predetermined thresholds to detect leaks and blockages.

摘要： A method for estimating a temperature profile for individual combustion cans at an inlet of a gas turbine is disclosed. In an exemplary embodiment, the method includes determining an exhaust temperature profile of exhaust gas of the gas turbine, and inputting the exhaust temperature profile into a model-based estimator of turbine components through which turbine gas flows. The model-based estimator calculates an estimated inlet temperature profile at the gas turbine inlet, based upon the exhaust temperature profile and design parameters of the gas turbine, the estimate inlet temperature profile being indicative of the actual firing temperature of each of the individual combustion cans.

摘要： A method of minimizing undesirable emissions from and acoustic pressure oscillations in a gas turbine includes the step of coordinating modulation of turbine fuel and air supply signals to maintain the fuel air ratio (FAR) within a selected range. Coordination of the modulation of fuel and air supply signals includes the steps of producing a turbine fuel supply control signal in correspondence with a turbine speed error signal, generating a coordinated turbine exhaust temperature error signal by modifying a preliminary turbine exhaust temperature error signal in correspondence with the derivative of the speed error signal, and producing a turbine air supply control signal from the coordinated turbine exhaust temperature error signal; the coordinated turbine exhaust temperature error signal provides coordination between the turbine fuel supply signal and the turbine air supply signal so as to maintain the fuel-air ratio of the combustible mixture being fed to the turbine within the selected range.
