Implementation of an IEC61850 Virtual Relay Network in a Protection Laboratory

Abstract:

Electrical protections fulfill an elementary function within electrical power systems, it is a field that is constantly changing according to the needs of each of the equipment. The document presents the implementation of a virtual relay that will have a configuration equal to that made in the physical relay. In this case study, a subtransmission line will be analyzed in which there will be a main protection (distance relay) and a backup protection (overcurrent relay) and the necessary adjustments will be made for each of them. Both GOOSE and MMS messaging are configured through an IEC 61850 station with the help of the IEC 61850 System Configurator® software. As a last point, obtaining the SCL files necessary to duplicate the physical relay in a virtual relay using the IEDScout software will be analyzed. Horizontal communication in GOOSE and MMS between the virtual relays and the server was validated.
