    Abstract: Systems and methods for automating commissioning of a gas turbine combustion control system are provided. According to one embodiment of the disclosure, a system may include a controller and a processor communicatively coupled to the controller. The processor may be configured to run a gas turbine under a plurality of operational conditions while within predetermined combustion operational boundaries. The processor may be further configured to automatically collect operational data associated with the gas turbine while the gas turbine is running and store the operational data. Based at least in part on the operational data, a set of constants for one or more predetermined combustion transfer functions is generated. The set of constants is stored in the gas turbine combustion control system to be used during auto-tune operations of the gas turbine.

    Abstract: Systems and methods for avoidance and correction of potentially adverse combustion states such as flame holding and flashback are disclosed. According to one embodiment of the disclosure, one or more sensors acquire sensor data from one or more sensors associated with combustion. An operational limit margin (OLM) is calculated using an OLM model and based at least in part on the sensor data. A determination is made as to the presence of a potentially adverse combustion state based at least in part on the OLM and the model. Once determined, corrective action may be taken to avoid an adverse combustion event prior to occurrence of the event.

    Abstract: Systems, program products, and methods for detecting thermal stability within gas turbine systems are disclosed. The systems may include a computing device(s) in communication with a gas turbine system, and a plurality of sensors positioned within or adjacent the gas turbine system. The sensor(s) may measure operational characteristics of the gas turbine system. The computing device(s) may be configured to detect thermal stability within the gas turbine system by performing processes including calculating a lag output for each of the plurality of measured operational characteristics. The calculated lag output may be based on a difference between a calculated lag for the measured operational characteristics and the measured operational characteristic itself. The calculated lag output may be also be based on a time constant for the measured operational characteristics. The computing device(s) may also determine when each of the calculated lag outputs are below a predetermined threshold.

    Abstract: Systems, program products, and methods for adjusting operating limit (OL) thresholds for compressors of gas turbine systems based on mass flow loss are disclosed herein. The systems may include at least one computing device in communication with the gas turbine system, sensor(s) measuring operational characteristic(s) of the gas turbine system, and a pressure sensor measuring an ambient fluid pressure surrounding the gas turbine system. The computing device(s) may be configured to adjust operational parameters of the gas turbine system by performing processes including determining a mass flow loss between an estimated, first mass flow rate and a calculated, second mass flow rate for the compressor of the gas turbine system, and adjusting an OL threshold for the compressor of the gas turbine system based on the mass flow loss. The OL threshold for the compressor may be below a predetermined surge threshold for the compressor.

    Abstract: A system and method control a gas turbine subject to fuel composition variation. The method includes operating a first effector to control the gas turbine based on fuel composition. The method also includes operating a second effector to maintain operation of the first effector within a first boundary limit, the second effector operation being initiated when the operating the first effector reaches a second boundary limit within the first boundary limit.

    Abstract: Systems and methods for controlling mode transfers of a turbine combustor are provided. According to one embodiment, a system may include a controller to control a combustor, and a processor communicatively coupled to the controller. The processor may be configured to receive current operating conditions, target operating limits, and combustor transfer functions. The combustor transfer functions may be evaluated to estimate operating limits associated with one or more combustion modes under the current operating conditions. The estimated operating limits associated with the one or more combustor modes may be compared to the target operating limits, and, based on the comparison, at least one of the combustion modes may be selected. The combustor may then be selectively transferred to the selected combustion mode.
