A contractor hands over an SCD file claiming it matches the actual device configuration. But how do you verify that quickly and provably when there are 76 IEDs on site and no permanent monitoring system? A field case from Tekvel: the verification module in the Tekvel Magic software automatically compared the device configurations against the SCD and produced an engineering deviation report covering DataSets, GOOSE, Sampled Values and MMS reports in 15 minutes.
CIGRE's first dedicated framework for virtualised IEDs will not publish until Q1 2028 — but the vPAC pilots that have to align to it are being commissioned now. Its scope is already public, through the working group's Terms of Reference and a framework article refeatured in ELECTRA 345 (April 2026): what is mandatory, what is deliberately out of scope, and what every 2026 vPAC pilot should already be doing in response.
How to use the dumpcap command-line utility for stable long-term network traffic capture — without Wireshark freezes or crashes.
8 out of 10 configurators fail to fully recognize SCD files. We analyze the confRev attribute in GOOSE and SV: what happens when the value does not match the expected one, and how this nearly derailed the commissioning of a real project with 43 IEDs.
Top-down IEC 61850 engineering — formalized in TR IEC 61850-90-30:2025 and TR IEC 61850-7-6 (Ed. 2) — moves specification errors from commissioning to the design phase, before a single IED is selected or procured. This article explains the mechanics of the five-step process: what each step produces, what files are exchanged, and why the sequence achieves outcomes the conventional bottom-up approach cannot.
Since the UpGrid forum started, many experts were quick to "bury" the exhibition "Electrical Grids of Russia" - the event participation in which is a longterm tradition for electric power engineers all over Russia. We had the feeling that UPGrid - it's more for "white collars", while LEP (as is often simply referred to) - is the place where you meet designers, maitenance engineeres, including specialists from different parts of Russia - those who work directly with the equipment on the ground. And, you know, our assumption looks true. "Digital Substation" prepared a special report from the eve
TEKVEL company presented a free beta version of JAVA-based IEC 61850-9-2LE software simulator. Digital Substation immediately downloaded the application and offers an express overview of the proposed software.
