Embodiments of the disclosure provide a method for operating a combined cycle power plant (CCPP). The method may include creating a variant control profile for the CCPP for a power plant model of the CCPP. The method may include modifying the variant control profile in response to the variant control profile not reducing the fuel consumption or meeting the quality threshold. The method may also include adjusting the CCPP to use the variant control profile in response to the variant control profile reducing the fuel consumption and meeting the quality threshold. Using the variant control profile adjusts a turbine section inlet temperature schedule or an exhaust temperature schedule for the CCPP.

Modeling and control of gas cycle power plant operation with variant control profile

Embodiments of the invention can provide systems and methods for condition-based power plant sensor calibration. According to one embodiment of the invention, a system can be provided. The system can include a computer processor. The system can also include a memory operable to store computer-executable instructions operable to: receive data from the one or more power plant sensors; reconcile detected errors within the data from the one or more power plant sensors; calibrate the one or more power plant sensors based at least in part on the detected errors within the data; generate at least one performance model based at least in part on the reconciled data from the one or more power plant sensors; detect anomalies within the at least one performance model; and tune the at least one performance model to account for the anomalies.

Systems and methods for condition-based power plant sensor calibration

A method of performance calculation and comparison is provided and includes collecting, at a central location, data relating to a performance characteristic of a machine, calculating at the central location and from the collected data, the performance characteristic of the machine and comparing the calculated performance characteristic with a target performance characteristic.
