Systems and methods for detection of combustor stability margin |
摘要 |
The present invention comprises systems and methods for determining stability margin of a combustor. One embodiment of the present invention includes the steps of providing a measuring device in communication with the combustor, wherein the measuring device generates signals indicative of combustor quantities; performing an autocorrelation calculation on the signals to determine the correlation time of the signals in the combustor; and determining the damping coefficient from the autocorrelation calculation, wherein the damping coefficient signifies a proximity of the combustor to instability. The damping coefficient may be estimated from the oscillatory envelope of the autocorrelation calculation data.
