Compressor blade monitoring system

摘要

A system 2 including: at least one computing device 120 configured to monitor a compressor blade 10 in a turbomachine 5 by: extracting time of arrival (TOA) data about the compressor blade 10 at a defined interval; correlating turbomachine operating conditions with the TOA data; extracting resonance data about the compressor blade 10 during startup or shutdown of the turbomachine 5, and extracting static deflection and tip clearance data about the compressor blade 10 during steady state operation of the turbomachine 5; creating a baseline compressor blade comparison level based upon the extracted resonance data, extracted static deflection and tip clearance data, and correlation between the turbomachine operating conditions and the TOA data; and iteratively extracting updated TOA data and performing the correlating, the extracting of the resonance data, static deflection and tip clearance data using the updated TOA data at the defined interval to create an updated baseline compressor blade comparison level. Corresponding computer program product with a program code executed by such a computing device.
