1. A system for detecting an anomaly in a combustion section of a gas turbine, the system comprising:

  • a plurality of combustors associated with a combustion section;

    a plurality of thermal sensors disposed at an exhaust section of a gas turbine, wherein the thermal sensors are configured to provide exhaust profile data of the gas turbine;

    a processing circuit communicatively coupled to a memory, the memory storing instructions which when executed by the processing circuit perform operations comprising;

    receiving, from the plurality of thermal sensors, the exhaust profile data of the gas turbine;

    analyzing the exhaust profile data to calculate statistical features associated with a peak-trough pattern;

    determining, using an algorithm or model, that the statistical features are abnormal; and

    in response to the determination, continuing processing of the exhaust profile data for a predetermined period of time; and

    reporting an anomaly in the combustion section of the gas turbine when the statistical features remain abnormal for the predetermined period of time.
