Abstract
A power generation plant including a plurality of combustor cans, one or more sensors configured to measure acoustic vibrations from the plurality of combustor cans, and a controller that includes a processor. The processor is programmed to identify a dominant tone of the measured acoustic vibrations, the dominant tone being a frequency where a highest amount of energy lies, determine, for each of the plurality of combustor cans, a frequency of the dominant tone at predefined time intervals, and determine a degradation status of at least one of the plurality of combustor cans based on the frequency of the dominant tone at each of the predefine time intervals for the at least one of the plurality of combustor cans.
