Abstract:
1. A method for operating components of a heat recovery steam generator (HRSG), comprising: receiving, via at least one processor, one or more HRSG operational design parameters; receiving, via at least one processor, one or more HRSG physical design parameters; monitoring, via at least one processor, real-time thermal stress data and real-time transient data from one or more sensors in communication with one or more HRSG components; determining, via at least one processor, real-time transient-related life consumption data and real-time cycle-related life consumption data associated with the one or more HRSG components based at least in part on the HRSG operational design parameters, physical design parameters, and the monitored thermal stress data and transient data, wherein the transient-related life consumption data and cycle-related life consumption data comprise at least one of measured calculations or instantaneous calculations; receiving real-time indications for a consumer demand for energy and a corresponding price for the energy; based at least in part on the transient-related life consumption data, cycle-related life consumption data, demand for energy, and corresponding price for the energy, providing a recommendation to operate the HRSG in a particular mode, wherein the particular mode is at least a control scheme, data aggregation, historical retention, or a repair scheme; and based at least in part on the recommendation, implementing, via at least one processor, the particular mode.
