Digital Substation is an engineering publication focused on IEC 61850 automation, protection systems, and digital grid intelligence.
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.
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.
IEC TC 57 distributed a proposal from ENTSO-E to add some features to IEC 61850 (57/1771/DC).
IEC TC 57 has published (57/1767/NP) a proposal for extending the System Configuration Language (SCL) to provide high-level direction in terms of how best to bind the HMI graphical objects with the IEC 61850 data objects/attributes using the configuration description language defined in IEC 61850-6. The concept willl be based upon the existing System Configuration Language (SCL) defined in IEC 61850-6, in addition to possibly incorporating other non-IEC namespaces such as the W3C's Scalable Vector Graphics (SVG) namespace.
IEC TC 57 proposes a new work item (57/1768/NP) IEC 61850-7-7: Communication networks and systems for power utility automation – Part 7-7: Basic communication structure – Machine-processable format of IEC 61850-related data models for tools (proposed 61850-7-7). Closing date for voting: 2016-11-25.
GOOSE-messaging has been covered a lot in many technical papers and to add anything valuable to the subject is rather difficult. But we will try. And functional constrained data will help us with that.
