Most digital substation projects are single-vendor, single-site proofs of concept. RTE — the operator of France's 2,600-substation transmission grid — decided to do something harder: build a fully digital, multi-vendor PACS from scratch, act as its own system integrator, and scale it across the entire network.
Last year Relyum launched a time-aware Redbox-DAN PCIe network interface RELY-SYNC-HSR/PRP-PCIe. Taking a brief look at the device.
IEC TC 57 has proposed a new part for IEC 61850 (57/1766/DC): IEC TR 61850-90-20 - Communication networks and systems for power utility automation – Part 90-20: Guideline to redundancy systems. As more application domains are added to the IEC 61850, additional modelling, description and functional capabilities needs to be added to the “core” of IEC 61850. And one of such capabilities is redundancy.
In Electric Power Networks of Russia-2014 exhibition MOXA presented DA-820 industrial computer which supports PRP and HSR redundancy protocols. Now process control systems manufacturers and suppliers can use this platform to offer workstations for integration in IEC 61850 station bus networks without redundancy boxes.
