Abstract: A system includes a power generation system and a controller. The controller includes processors that receive a first set of inputs. The processors also generate a first set of modeled outputs system based on a model of the power generation system and the first set of inputs. The processors further receive a first set of measured outputs corresponding to the first set of modeled outputs. The processors determine a first correction factor based on the first set of modeled outputs and the first set of measured outputs. The first correction factor includes differences between the first set of modeled outputs and the first set of measured outputs. The processors also generate a second set of modeled outputs based on the model, a second set of inputs, and the first correction factor. The processors further control an operation of the power generation system based on the second set of modeled outputs.

Abstract: A method of controlling purge flow in a gas turbomachine system includes detecting a fault condition in the gas turbomachine system, initiating a shutdown of the gas turbomachine system, introducing a purge flow into a gas turbine portion of the gas turbomachine system, categorizing the fault condition as one of a category one fault and a category two fault, and validating the purge flow if the fault condition is a category one fault and invalidating the purge flow if the fault condition is a category two fault.

Abstract: A method includes determining, via a processor, a commanded fluid flow rate of a fluid entering or exiting the drum of an industrial system, wherein the commanded fluid flow rate comprises a rate of fluid entering the drum of the industrial system, exiting the drum of the industrial system, or a combination thereof. The method additionally includes determining, via the processor, a measured flow rate of the fluid. The method further includes determining, via the processor, a variable multiplier based at least in part on the commanded fluid flow rate and the measured flow rate; and deriving, via the processor, a multiplied flow rate command for the industrial system by applying the variable multiplier to the commanded fluid flow rate.

Abstract: Systems and methods for automatic feedback control are provided. According to one embodiment of the disclosure, a method for automatic feedback control may commence with receiving high-level control references by a low-level controller communicatively coupled to a high-level controller via the network connection. The method may further include generating, by the low-level controller, low-level control references for a hardware asset based at least in part on the high-level control references. The method may continue with transferring control of the hardware asset to the low-level controller in response to a loss of the network connection. The method may further include adjusting the low-level control references by a low-level control mechanism associated with the low-level controller in response to the loss of the network connection.

Abstract: Exemplary embodiments described in this disclosure pertain to a system that includes a high-level controller coupled to a low-level controller in an arrangement that allows the high-level controller to cooperate with the low-level controller for controlling a power generation unit. The high-level controller generates supplementary signals and/or supplementary code that is provided to a surrogate controller. The surrogate controller uses the supplementary signals and/or supplementary code to generate control software that is provided to the low-level controller for controlling certain operational aspects of the power generation unit that cannot be independently controlled by the low-level controller. If the high-level controller is placed in an independent mode of operation for any reason, the surrogate controller continues to cooperate with the low-level controller for controlling various operations of the power generation unit that were being controlled by the low-level controller prior to the high-level controller entering the independent mode of operation.

Abstract: A fuel supply system for use in a gas turbine engine is provided. The fuel supply system includes a fuel manifold, and a shutoff valve coupled in flow communication with the fuel manifold and positioned upstream from said fuel manifold. The shutoff valve is configured to actuate into a closed position when the gas turbine engine is operating at an overspeed condition. The system also includes a relief valve coupled in flow communication with the fuel manifold, wherein the relief valve is configured to release fuel from within the fuel manifold when the shutoff valve is in the closed position, and when a pressure within the fuel manifold is greater than a first predetermined threshold.
