Abstract

This paper presents simulation software that allows the efficient and accurate fixed-time-step simulation of complex switched electrical systems. The software, named ARTEMIS (Advanced Real-Time Electro-Mechanical Transient Simulator), accurately simulates time-segment linear systems with discontinuities occurring anywhere between time-steps. This paper focuses on the simulation of a DC-AC converter with ARTEMIS Discrete Time Compensation of Switching Events (DTCSE) algorithm and the RT-EVENTS algorithm, highlighting the benefits of the software in real-time applications.

Abstract

This paper describes the architecture and specifications of advanced real-time simulators capable of accurately simulating electrical power grids and power electronic systems of any size. The OPAL-RT eMEGAsim simulator is based on modern high-performance distributed supercomputer technology comprised of off-the-shelf INTEL or AMD multi-core processors. Several eight-processor shared-memory supercomputer modules are interconnected with fast PCI Express communication links and IO systems controlled by Field Programmable Gate Array (FPGA) Xilinx processors capable of executing sub-system models with time step below 250 nanoseconds. A brief history of the evolution of real-time simulators will be given followed by the main specification requirements for each type of application, a description of the simulator architecture and a typical application case.
