Substation Communications

Network Solutions and their Usability in Substation Applications

During the last 10 years, reliable industrial networking based on Ethernet became a vital issue for substation automation applications. Especially the trend to replace the discrete wiring using the so called IEC 61850 GOOSE  mechanism leads to redundant Ethernet network layouts ensuring N-1 redundancy, repairing a one-fault situation. Lots of articles have been published already, but new redundancy mechanisms are coming up and will influence the substation automation business. This article gives an overview about the needs, today’s solutions, and upcoming technologies. More
