DEMO | Testing an SEL Protection Relay in a Real-Time Hardware-in-the-Loop Simulation of a Microgrid | OPAL-RT Learning Journey

Author : Chris Genganantha

Hardware-in-the-Loop (HIL) testing has been adopted as a standard technique for the development, validation and integration of power system control and protection equipment. In this presentation, we demonstrate how HYPERSIM® remains a powerful real-time electromagnetic transient (EMT) simulation tool for the HIL testing of this same power system protection equipment. The GHOST microgrid model, based on the BANSHEE distribution network developed at MIT and NREL, is a distribution level power system model comprised of three feeders having various Distributed Energy Resources (DERs), including solar, diesel, and battery energy storage systems. The model featured in this demo is run on an OPAL-RT real-time simulator, which is used to send voltage and current measurements in real time to a physical protection relay from SEL, which is interfaced with the simulation. Using the IEC 61850 GOOSE protocol, the demo features both fault and islanding scenarios to highlight the ease and utility of HYPERSIM® as a real-time simulation tool.
