Abstract: Systems and methods for improved control of a turbomachine system with a bottoming cycle system are presented. The systems and methods include a controller that utilizes modeling techniques to derive a plurality of load path curves. The controller utilizes a current load path, a minimum load path, and a constant efficiency load path. The systems and methods include a control process configured to receive a user input representative of a life cycle control modality and to execute a control action based on deriving a load efficiency by applying the current load path, the minimum load path, the constant efficiency load path, or a combination thereof, and the life cycle control modality. The control action is applied to control the turbomachine system and the bottoming cycle system fluidly coupled to the turbomachine system. Further, the life cycle control modalities may be selected by a user based upon known tradeoffs.

Abstract: A system, method and computer-readable medium for monitoring a life of a gas turbine component is disclosed. A numerical model of the gas turbine component is created and parameter measurements are obtained in real-time for at least a portion of the gas turbine component. The parameter measurements are fused with a subset of the numerical model corresponding to the portion of the gas turbine component to obtain a subset of a fused parameter model corresponding to the portion of the gas turbine component. The subset of the fused parameter model is expanded to obtain the fused parameter model that corresponds to at least a location outside of the portion of the gas turbine component. The life of the gas turbine component is monitored using the fused temperature model.

Based on the comparison, the processor can determine that a difference between the realtime data and the reference data exceeds a predetermined threshold. If the difference exceeds the predetermined threshold, the processor can notify operators of an anomaly in the one or more hot gas path components.
