SYSTEMS AND METHODS RELATED TO DETECTING FLAME BLOWOUT OCCURRENCES IN GAS TURBINES

A system for controlling an operation of a combustor (13,30) in a gas turbine (27) that includes: an acoustic sensor (62) configured to periodically measure a pressure of the combustor (13,30) and generate a raw data stream having the pressure data points resulting from the periodic measurements; an...

Beschreibung
Zusammenfassung:	A system for controlling an operation of a combustor (13,30) in a gas turbine (27) that includes: an acoustic sensor (62) configured to periodically measure a pressure of the combustor (13,30) and generate a raw data stream having the pressure data points resulting from the periodic measurements; and a blowout detection unit (75) configured to receive the raw data stream from the acoustic sensor (62). The blowout detection unit (75) may include a processor (81) and a machine-readable storage medium on which is stored instructions that cause the processor (81) to execute a procedure related to a detection of a blowout precursor. The procedure may include an ensemble approach in which the detection of the blowout precursor depends upon a outcomes generated respectively by separate detection analytics.
