Digital Substation is an engineering publication focused on IEC 61850 automation, protection systems, and digital grid intelligence.
A local area network is critical infrastructure in a digital substation. Experts in the area of relay protection and automatic as well as automated process control systems run into it with increasing frequency, while the number of questions such as, ‘How to design it?’, ‘How to maintain it?’, ‘How to evaluate its security and effectiveness?’ only increases.
German company Ziehl presented the new version of temperature sensor TR1200 - now it supports GOOSE-messaging.
To meet the needs of both operational technology (OT) and information technology (IT) networks, SDN is emerging as a superior solution.

The number of Ethernet switches with integrated IEC 61850-8-1 server increases. Manufacturers do not only implement standard logical node classes according to IEC 61850-7-4 but also those ones introduced by IEC 61850-90-4 technical report. These switches do also support buffered and unbuffered reporting mechanisms. Seems like the closest future is the one where IEC 61850-8-1 (MMS) communications will replace communications over SNMP (being widely used at the moment). This will allow for integration of Ethernet switches in process control systems the same way as it is done with IEC 61850-8-1 pr
Updated test register includes a lot more IEC 61850-9-2LE conformant stand-alone merging units and IEC 61850-8-1 ed. 2.0 conformant devices.
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.
Siemens presented the new series of arc-fault protection devices 7XG31. The new series includes 7XG3124 RA24 device which is capable of transmitting GOOSE messages on detection of arc-faults in different compartments of enclosed switchgear. It is possible to...
