A Common User Interface for Offline and Real-time Simulation of Transients

This paper presents EMTP-RT, a real-time toolbox developed for use with EMTP-RV - an application for the simulation and analysis of electromagnetic transients. EMTP-RT enables users to share a single, unique graphical user interface (GUI) for both offline and real-time hardware-in-the-loop (HIL) simulation of transients. The growing need to conduct real-time HIL studies presents new challenges to users of classic offline transient simulation applications. These challenges include the requirement for models to be separated and distributed across multiple processors to reach the computational performance required for real-time simulation, for extra tools to be added for data visualization and synchronization, and for the design interface to contain an HIL interface for model communication with actual analog and digital signals.
