Gas turbine combustion profile monitoring
First Claim
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.

Abstract
Systems and methods for gas turbine combustion profile monitoring are disclosed. In one embodiment, a method for detecting an anomaly in a combustion section of a gas turbine is disclosed. The method includes receiving, from a plurality of thermal sensors disposed around an exhaust section of a gas turbine, exhaust profile data of the gas turbine. The method further analyzes the exhaust profile data to calculate statistical features associated with a peak-trough pattern. The method further determines, using a machine learning algorithm, that the statistical features are abnormal. In response to the determination, the method processes the exhaust profile data for a predetermined period of time and reports an anomaly in a combustion section of the gas turbine if the statistical features remain abnormal for the predetermined period of time.
