<P>PROBLEM TO BE SOLVED: To provide a system for monitoring normality of a compressor blade. <P>SOLUTION: In one embodiment, a blade monitoring system 120 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 4; calculating, using the dynamic component, at least one of: a natural frequency of the GT compressor blade 10 during the load change, an overshoot of the GT compressor blade 10 during the load change, a rise time of the compressor blade 10 during the load change, a damping factor of the compressor blade 10 during the load change, or a settling time of the GT compressor blade 10 after the load change; and determining whether the GT compressor blade 10 is damaged based upon the at least one of: the natural frequency, the overshoot, the rise time, the damping factor, or the settling time. <P>COPYRIGHT: (C)2012,JPO&INPIT |
