Digital Substation is an engineering publication focused on IEC 61850 automation, protection systems, and digital grid intelligence.
We analyzed the full UCA IUG conformance registry — all 1,650 records across three editions. The result: in 2025, three out of four new IEC 61850 certificates were Ed.2.1. The tipping point has already passed.
South Africa's Eskom is building a self-healing grid through AI, FLISR, smart metering and microgrids — backed by a R321 billion five-year capex plan. Here's what is actually deployed, what is still being developed, and what the engineering numbers say.
A technical overview of how SCADA systems integrate with digital substations for real-time monitoring and control.
If you have ever opened an SCL file from another vendor and wondered whether it is actually correct — not just well-formed XML, but semantically valid against the IEC 61850 standard — you already understand the problem that OCL is trying to solve.
The Brainstorm block is a collection of industry experts’ opinions on actual problems. It allows specialists to look at different problems from different perspectives.
The System Operator of the Unified Energy System (SO UES) has published comprehensive data on the operation of relay protection and automation devices (RPA) within the Russian Electric Power System (EPS) for the calendar year 2023. This report aims to provide a detailed analysis of the operational integrity and challenges faced by these critical components in ensuring the stability and reliability of the power grid.
