About this webinar
XSD validation can confirm that an SCL file is structurally correct, but it cannot express every engineering requirement that determines whether a substation configuration is actually consistent and acceptable. Object Constraint Language (OCL) extends validation with formal, machine-readable rules that can be checked automatically. In this webinar, we will explain the role of OCL in IEC 61850, review the rule sets already developed within IEC TC57 WG10, and discuss how utilities can use OCL to formalize their own engineering requirements. We will also briefly look at the open-source reference tooling and demonstrate a practical utility workflow using Tekvel Park.
What you will learn
- Understand why XSD validation alone is not sufficient for complete SCL/SCD quality checks.
- See how OCL can turn engineering requirements into formal rules that are checked automatically.
- Learn what standard OCL rule sets already exist in the IEC 61850 ecosystem and how they can be applied.
- See how utility-specific rules can be managed and applied consistently across projects and SCD files.
- Watch a live demonstration showing the difference between structural validation, standard OCL checks and corporate OCL requirements.
Who it's for
- Utility protection, automation and digital-substation engineers responsible for IEC 61850 specifications, engineering and acceptance.
- Utility experts defining corporate SCL/SCD requirements, naming conventions and standard engineering practices.
- System integrators and engineering organizations preparing or reviewing SCD files for utility projects.
- IEC 61850 specialists who want to understand how OCL complements conventional XSD validation.

Speakers
Alexey Anoshin — Founder and CEO of Tekvel · IEC 61850 and digital substation trainer
Founder and CEO of Tekvel · IEC 61850 and digital substation trainer Alex has spent over 15 years working on IEC 61850 and protection, automation and control (PAC) systems — as an engineer, product developer, consultant and educator. He founded Tekvel in 2012 and has since trained more than 3,500 engineers worldwide through hands-on and theoretical programs on IEC 61850 and digital substation technologies. His training draws directly on real project experience. At Tekvel he led the development of Tekvel Park, a communication monitoring and diagnostics system for digital substations, and Tekvel Magic, a simulation tool that brings CI/CD principles to the routine testing and maintenance of PAC systems. He has delivered multiple IEC 61850 engineering projects, including the commissioning of a fully centralized, server-based protection and control system for a utility. Before Tekvel, Alex established a multi-vendor Digital Substation Laboratory at Moscow Power Engineering Institute, where he taught protective relaying reliability and ran practical lab courses, and helped bring an RTDS real-time simulator into research and protection scheme validation. Earlier roles at Profotech and Tavrida Electric involved introducing fiber-optic instrument transformers and new medium-voltage switchgear to the market, and he co-founded Releyshik, a magazine for PAC engineers. Alex is a member of CIGRE and IEC TC 57 WG10, the working group that maintains the IEC 61850 standard, and has presented papers at CIGRE SC B5. He holds MSc and BTech degrees in Electrical Engineering from Moscow Power Engineering Institute and is certified in RTDS Simulator Levels I and II. He teaches in English and Russian.
