Simulation of the control system for the 12-Pulse bridge

Abstract

This article made a study of various schemes’ options and control algorithms for 12-pulse thyristor bridge rectifiers. While maintaining the same speed’s modes were analyzed changes of the power factor and harmonic composition of current and voltage, as well as was assessed their level based on the IEEE 519-1992 standard. Simulation of the electric power system has been performed in the software environment Matlab. The aim of the job is to identify the most suitable ways of connecting and control thyristors schemes for improving power factor and harmonic composition of current and voltage. The results of the work will be put in a series of activities to effectively phase manage the rolling mill drives’ distributed power converters.
