Adjustable Speed Control and Damping Analysis of Torsional Vibrations in VSD Compressor Systems

چکیده
This paper proposes a model-based two-degree-of-freedom (2DOF) speed control for medium voltage (MV) variable drive (VSD) connected to centrifugal compressor (CC) train. Torsional mode excitations in the shaft due converter switching behaviour are considered. An effective description of harmonics transfer is proposed. The tuning strategy aims optimize tracking step and ramp command, taking care critical excitations. stability closed-loop dynamics against time delay parameter variations studied by means Nyquist diagrams time-domain simulations. A descriptive method process damping evaluated through simulations as well an experimental setup, based on hardware loop (HIL) master–slave configuration.

Power Electronic Devices for Damping Torsional Vibrations
Torsional vibrations and resonance problems with synchronous machines are most frequently encountered in rotor systems with long shafts and large inertias constituting a weakly damped mechanical resonator which exhibits a low resonance frequency. It is impossible to obtain a effective mechanical damping for these torsional vibrations, but by using a power electronics device and an inductive or ...

ABSTRACT. This paper is concerned with the torsional vibrations of a nonhomogeneous magnetostrictive elastic cylinder. The cylinder is subjected to the action of a circumferential magnetic field produced by an axial current of constant density and the deformation of a magnetostrictive cylinder is produced by a constant longitudinal magnetic field. The frequency equation is determined, and the d...
