SYSTEM AND METHOD FOR OPERATING A GAS TURBINE

摘要

A system for operating a gas turbine includes a controller configured to execute logic stored in a memory that causes the controller to determine two or more of a frequency, a coherence, a phase, and an amplitude, of a combustion instability; to compare two of more of the frequency, the coherence, the phase, and the amplitude of the combustion instability to a respective predetermined limit; and to adjust at least one parameter of the gas turbine if two or more of the frequency, the coherence, the phase, and the amplitude of the combustion instability are actionable relative to their respective predetermined limits. A related method of operating the gas turbine is also disclosed.

1. A system for operating a gas turbine, the system comprising:
a. a compressor section configured to receive a working fluid and to produce a compressed working fluid; b. a plurality of combustors downstream from the compressor section, each combustor comprising a fuel injector, the fuel injector receiving fuel at a fuel temperature and a fuel flow rate; and c. a controller configured to execute logic stored in a memory, the logic causing the controller:
i. to determine a phase of a combustion instability and an amplitude of the combustion instability;ii. to compare the phase of the combustion instability to a predetermined phase limit and the amplitude of the combustion instability to a predetermined amplitude limit; andiii. to adjust at least one parameter of the gas turbine if the phase of the combustion instability is actionable relative to the predetermined phase limit and the amplitude of the combustion instability is actionable relative to the predetermined amplitude limit.
