Utilizing a combined empirical and deterministic model for automated tuning of gas turbine combustion systems

A gas turbine combustion system, comprising:

• a combustion engine comprising a plurality of actuatable components;
• one or more sensors that are to measure one or more operating conditions of the combustion engine;
• and
• a tuning controller including non-transitory memory and executable instructions, stored in the non-transitory memory, that, if executed by one or more processors of the tuning controller, cause the tuning controller to:
• receive, from the one or more sensors, a plurality of input parameters comprising exhaust emissions levels, combustor dynamics, exhaust temperatures, compressor inlet and outlet temperatures and pressures, heat recovery steam generator (HRSG) critical system parameters, and/or fuel system parameters;
• retrieve a plurality of thresholds to which the plurality of input parameters are to be respectively compared;
• and
• cause one or more operational control parameters, that are to control at least a portion of the plurality of actuatable components, to be proportionally adjusted based, at least in part, on an amount of deviation of an input parameter of the plurality of input parameters from a respective threshold of the plurality of thresholds, the one or more operational control parameters comprising one or more of combustor fuel flow distribution reference, fuel gas inlet temperature, fuel gas inlet fuel composition, turbine exhaust temperature reference, or combustor bypass valve position.
