VSDS Motor Inverter Design Concept for Compressor Trains avoiding Interharmonics in Operating Speed Range
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
During operation of compressor trains by a variable speed
drive system (VSDS), integer and non-integer harmonic
currents are generated in the inverter. Via the electrical system
of the inverter and the motor, an excitation ...
RECIPROCATING COMPRESSOR CONDITION MONITORING
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Technology for reciprocating compressor condition monitoring has been around since the 1950’s, however until the last 20 years or so it seemed that only the pipeline companies spent much effort on this activity. Technology ...

ON-SITE DETERMINATION OF THE CONTROL LINE FOR INTEGRALLY GEARED COMPRESSORS FOR AVOIDANCE OF IMPELLER FATIGUE FAILURES
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
In this lecture a root cause analysis (RCA) is presented for a fatigue failure of a semi-open impeller of an integrally geared compressor. The compressor had been in service for about one year in an air separ
3rd stage impeller.
