Abstract
In one embodiment, a blade monitoring system includes: at least one computing device configured to monitor a compressor during a load change by performing actions comprising: extracting a dynamic component of a blade time-of-arrival (TOA) deviation signal in response to the load change on the compressor; calculating, using the dynamic component, at least one of: a natural frequency of the GT compressor blade during the load change, an overshoot of the GT compressor blade during the load change, a rise time of the compressor blade during the load change, a damping factor of the compressor blade during the load change, or a settling time of the GT compressor blade after the load change; and determining whether the GT compressor blade is damaged based upon the at least one of: the natural frequency, the overshoot, the rise time, the damping factor, or the settling time.
