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 ...
IMPACT OF ELECTRICAL NOISE ON THE TORSIONAL RESPONSE OF VFD COMPRESSOR TRAINS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
The popularity of VFD motors in compressor trains
has increased in recent years. Increased process flexibility is a
primary consideration for implementation of VFD systems.
