Abstract

This paper presents new simulation software that allows the efficient and accurate fixed-time-step simulation of complex event-based electrical systems. The software, named Advanced Real-Time Electro-Mechanical Transient Simulator (ARTEMIS™ ), accurately simulates time-segment linear systems with discontinuities occurring anywhere between time-steps. The new software is used for the simulation of energy and power system dynamics, and is implemented in the ARTEMIS™ add-on for Simulink’s Power System Blockset (PSB). With ARTEMIS™ real-time compensation of switching events (RTE), the between-step events are transparently taken into account and compensated for in the simulation results. This eliminates sub-synchronous jitter while causing only minor increase in both the average time-step and real-time time-step (typically <10%), making ARTEMIS™ with RTE suitable software for real-time simulation of precision-critical hardware-in-the-loop (HIL) electromechanical and drives systems. The RTE algorithm is very good at handling difficult fixed-step simulation cases, like multiple single time-step discontinuities encountered in the simulation of electric drives and power converters.
