Digital Substation is an engineering publication focused on IEC 61850 automation, protection systems, and digital grid intelligence.
In 2023, fourteen European TSOs signed a common statement on IEC 61850 engineering and demonstrated a working proof of concept. Their five-step top-down process — backed by two new IEC technical reports — changes how utilities, IED suppliers, and tool vendors interact. Here is what they built and why it matters.
The EN100 Ethernet communication module and SIPROTEC 5 relays are affected by security vulnerabilities which could allow an attacker to conduct a Denial‑of‑Service attack over the network.
National Grid, one of the world’s largest energy companies, has selected Siemens to provide technology to help deploy the IEC 61850 digital design standards for its bulk transmission substations.
The IEC 62443 standard is the first that provides a basis for IT security certification for industrial automation and control systems.
SIPROTEC 4 and SIPROTEC Compact users are recommended to check EN100 module firmware.
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...
Recently we have received binary signals input/output module by Siemens - SICAM IO UNIT 7XV5673. This device is absolutely new: as binary inputs/outputs expansion module it was presented last fall and, regarding to Siemens office, we were one of the first to try it out.
