Research on Digital Control Systems for Large Power AC-DC-AC Converters with Synchronous Motor Load

Abstract

Large power AC converters with synchronous motor load are widely used in field projects. In this article, hardware modules with VME-bus and graphical developing environment are used to construct a digital control system. This system is used to control a 5 MVA 3-level PWM AC-DC-AC IGCT converter with synchronous motor load. The open-loop control experiment result proves that using such a set of platform to construct the digital control system for large power AC-DC-AC converters with synchronous motor load is feasible. And the close-loop control experiment is in process
