On-line monitoring of hot gas path components of a gas turbine

摘要

Systems and methods for on-line monitoring of hot gas path components of a gas turbine are provided. According to one embodiment of the disclosure, a system may include a camera operable to monitor one or more hot gas path components of the gas turbine and a processor communicatively coupled to the camera. The processor is operable to receive realtime data from the camera monitoring the one or more hot gas path components of the gas turbine and compare the realtime data to reference data. Based on the comparison, the processor can determine that a difference between the realtime data and the reference data exceeds a predetermined threshold. If the difference exceeds the predetermined threshold, the processor can notify operators of an anomaly in the one or more hot gas path components.

1. A method for on-line monitoring of hot gas path components of a gas turbine, the method comprising:
receiving, by a processor, realtime data from a camera monitoring one or more hot gas path components of the gas turbine while the gas turbine is in operation, wherein the camera monitors the one or more hot gas path components in relation to one or more stationary components of the gas turbine to detect changes in a proximity between the one or more hot gas path components and the one or more stationary components; comparing, by the processor, the realtime data to reference data, wherein the realtime data comprises changes in the proximity between the one or more hot gas path components and the one or more stationary components; based at least in part on the comparison, determining, by the processor, that a difference between the realtime data and the reference data exceeds a predetermined threshold; and based at least in part on the determination, selectively notifying of an anomaly in the one or more hot gas path components.
