  • Relay Protection Virtual Platform Design

    Relay Protection Virtual Platform Design

    This whitepaper, co-authored by Intel and Kalkitech describes the virtual protection relay (VPR) concept – an architecture where software-defined and virtualized platforms are deployed to host the critical circuit protection functions for an advanced and agile grid. We assert that this use of. Edge Analytics the availability of IEC-61850-3 certified servers built for substations and VMware vSphere supporting latency-sensitive workloads in the substation. Modern substations require standardized, flexible, scalable, and secure systems to build a data-driven power grid to improve the local. A Virtual Protection Relay is a protection system implemented entirely in software instead of a physical relay box. We outline virtualizati n technology and the networking aspects using performance benchmarks laid by IEC 61850 standards. Protective relays have evolved steadily over time. Early power systems relied on electromechanical relays, which were later. As the energy sector is confronted with the high penetration of renewable energy sources, one of the key aspects of the grid controls which are put under stress is the grid protection sub-system.
