OCL in IEC 61850: Machine-Readable Rules for SCL Validation

XML Schema validation checks structure — it cannot verify that a GOOSE subscription references a valid dataset or that a logical node contains required data objects. Object Constraint Language (OCL) fills that gap. IEC TS 61850-6-3, published in 2025, defines how OCL rules should be written and applied to IEC 61850 XML files, laying the groundwork for consistent, formal SCL validation across tools.

Network infrastructure in digital substations

A local area network is critical infrastructure in a digital substation. Experts in the area of relay protection and automatic as well as automated process control systems run into it with increasing frequency, while the number of questions such as, ‘How to design it?’, ‘How to maintain it?’, ‘How to evaluate its security and effectiveness?’ only increases.
