Abstract: A system including a power plant having thermal generating units that operate according to multiple possible operating modes, which are differentiated by a unique operational or maintenance schedule. The system further includes a hardware processor and machine readable storage medium on which is stored instructions that cause the hardware processor to execute a process related to optimizing the operational or maintenance schedule during a selected operating period. The process may include: receiving the selected operating period; selecting competing operating modes for the power plant during the selected operating period according to a selection criteria; simulating the operation of the power plant during the selected operating period for each of the competing operating modes and deriving simulation results therefrom; evaluating each of the simulation results pursuant to a cost function and, based thereupon, designating at least one of the competing operating modes as an optimized operating mode.

Abstract: Embodiments of the disclosure relate to systems and methods to evaluate performance of a fluid transport system. Towards this end, a performance report of the fluid transport system can be generated by estimating various performance parameters at an outlet of a heat exchanger in lieu of using sensor data obtained directly from the outlet of the heat exchanger. Specifically, in one exemplary implementation, sensor data is obtained from an inlet of the heat exchanger and an outlet of a downstream element that is coupled to the heat exchanger, for estimating the various performance parameters at the outlet of the heat exchanger. The estimated performance parameters can then be combined with empirical data and predictive data for generating the performance report of the fluid transport system.

Abstract: A method for optimizing a fleet of generating assets in which groupings include remotely located power blocks that operate so to collectively generate a fleet output level. The method may include: receiving real-time and historical measured values of operating parameters; for each of the generating assets, deriving a relational expression between the measured values of the process inputs and the measured values of the process outputs; defining a selected operating period; selecting competing operating modes for the fleet; based on the relational expressions and a generating configuration of the competing operating modes, calculating a result set for the operation of the fleet proposed during the selected operating period; defining a cost function; and evaluating each of the result sets pursuant to the cost function and, based thereupon, designating one of the competing operating modes as an optimized operating mode. The optimized operating mode may include a power sharing recommendation between the power blocks of the fleet.

Abstract: In one example embodiment, a gas turbine system includes a gas turbine, a compressor bleed valve, various sensors, and a valve health assessment system. The compressor bleed valve bleeds a portion of air received by the compressor during certain operating modes. The valve health assessment system includes a processor that uses a neural network model to generate a first failure mode predictor of the compressor bleed valve by processing operational data provided by the various sensors. The processor also generates a second failure mode predictor of the compressor bleed valve by using empirical data and a valve transfer function. The processor further generates a third failure mode predictor of the compressor bleed valve by using predictive data and a prediction model. The processor then applies a holistic procedure to the three failure mode predictors to derive a probability of occurrence of a failure in the compressor bleed valve.
