    Abstract: A method for predicting an anomaly in a combustor (16) is presented. The method includes receiving signals representative of parameters in one or more combustion cans (22, 24) of the combustor, generating a plurality of patterns based on a permutation entropy window and the signals, identifying a plurality of pattern categories in the plurality of patterns, determining a permutation entropy based on the plurality of patterns and the plurality of pattern categories, and predicting an anomaly in the combustor based on the permutation entropy. The method further includes comparing the plurality of pattern categories to determined permutations of pattern categories if the anomaly is present in the combustor, and predicting a category of the anomaly based on the comparison of the plurality of pattern categories to the determined permutations of pattern categories.

    Abstract: A system may include a memory storing a turbomachinery degradation model configured to model degradation of a turbine system over time. Further, the system may include a controller communicatively coupled to the memory, which derives a turbomachinery wash timing based on at least one input signal from the turbine system and the turbomachinery degradation model. The turbomachinery degradation model may derive a desired wash point by estimating a modeled power of the turbine system, a modeled heat rate of the turbine system, or both. Furthermore, the controller may use the desired wash point to determine a time for washing components of the turbine system.

    Abstract: A monitoring system of a combined cycle power plant having a topping cycle performed by a gas turbine and a bottoming cycle performed by a steam turbine, the monitoring system. The monitoring system includes a processor that receives a first set of data indicating a first measurement value of an operating parameter of the combined cycle power plant. The processor determines a baseline efficiency of the process based on the first measurement value using a bottoming cycle performance (BCP) model. The processor determines a threshold based on the baseline efficiency. The processor receives a second set of data indicating a second measurement value of the operating parameter. The processor compare the threshold to an operational efficiency based on the second measurement value using the BCP model, and provides an indication of a decrease in efficiency of the process if the operational efficiency is below the threshold.

    Abstract: A combustion product control system includes a first sensing device that measures a concentration of NOx in a fluid stream and a second sensing device that measures NH3 slip in the stream. The system also includes at least one combustion product control element. The system further includes at least one processor coupled to the sensing devices and the control element. The processor is programmed to generate predetermined parameters for NOx values in the stream at least partially as a function of transient stream conditions. The processor is also configured to use model predictive control (MPC) processing to generate predetermined values for a NH3 injection rate during stream transients. The predetermined values vary at least partially as a function of modeled stream characteristics. The processor is further configured to regulate the control element to facilitate simultaneous regulation of the NOx and NH3 slip in the stream within respective predetermined parameters.
