Real-Time Simulation of a High-Power Cycloconverter Drive

This paper presents the use of a real-time simulation platform for the study of a high-power cycloconverter drive. Advantages of this strategy are reported, especially when compared to off-line simulation tools when evaluating electrical systems in presence of complex high-power static converters. Characteristics of a cycloconverter drive are presented, together with a real-time simulation model running in a multi-core platform from OPALRT. Time-domain simulation results with a time-step of 50μ s are shown. Capabilities of the model are exemplified with the analysis of two harmonic-current compensation strategies and the integration of the model with an external power converter for a power-hardware-in-the-loop application.
