SYSTEMS AND METHODS FOR MONITORING A COMPRESSOR

A method includes receiving sensor data from one or more combustors of a turbomachine, wherein the received sensor data includes a plurality of frequency signal amplitudes over a sample period, the one or more combustors disposed downstream of a compressor of the turbomachine, and the compressor includes a compressor stage with a plurality of blades disposed about the compressor stage. The process then identifies first harmonic frequencies of a first blade pass frequency of the plurality of compressor blades from the received sensor data, wherein the first blade pass frequency is based at least in part on a first quantity of the plurality of blades disposed about the compressor stage and a rotational speed of the compressor stage. The process then determines whether one or more of the plurality of frequency signal amplitudes corresponding to the identified first harmonic frequencies exceeds a first threshold value.
