The Torsional Torque Fluctuations of a Compressor Train with a Vector Control PWM Inverter

Abstract

A stable speed & torque control system is essential for large adjustable speed motor driven compressor trains. In order to achieve stable control, advanced control techniques are required. This case study shows the problems associated with & the countermeasures taken relating to the adjustable speed drive control. Investigation, simulation and a successful resolution of the problem achieved safe & stable compressor operation.
