Real-Time Control and Emulation of Multimachine Systems using eMEGAsim
Multimachine/Multiconverter systems are common in many applications of electrical and electromechanical systems, including: distributed power generation networks; web transport systems and winders in paper, plastic and metal industries; and electrical vehicles. Strong similarities exist in the characteristics and behaviors of these systems and it is interesting from an educational point of view and for training of systems engineers to study analog models.
We present modeling of a winder system, using force-current analogies, as an equivalent system that can be realized in the form of a distributed power generation system. The main system components are four AC induction motors, four voltage source inverters (VSI) and four DC generators, coupled mechanically and electrically - ARTEMiS, Opal-RT’s solver that enables the real-time simulation of power electronic systems, was instrumental in simulating the system stably and efficiently.
A test bed was designed for real-time control using eMEGAsim, for motor velocity control and line current control, where eMEGAsim directly generates control pulses for the four VSI. Experimental results are presented for a 2 motor-set system used for voltage sag studies and the configuration of the full 4 motor-set system is described.
