IEC TR 61850-7-6:2024

Overview

IEC TR 61850-7-6:2024 - "Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850" is a Technical Report that defines a methodology to create Basic Application Profiles (BAPs) for power utility automation. The second edition updates the 2019 release and introduces a machine-processable representation of BAPs in SCL (Substation Configuration Language), guidance on expressing BAPs in SCL files (new Clause 5), and new annexes describing use cases and the Concept Definition Tool (CDT) roles. The report focuses on specifying typical information exchange (data, communication services, engineering conventions) to enable modular, interoperable implementations of IEC 61850 application functions - not on device-level implementation requirements.

Key Topics and Requirements

• BAP methodology and profiling concept: How to define a subset of IEC 61850 features to describe application behavior consistently across implementations.
• Machine-processable BAPs in SCL: Templates, .ASD file structure, SCL extensions, UUID traceability, validation and instantiation processes for engineering tools.
• Interoperability artifacts: Definitions of Basic Application Interoperability Profiles (BAIOPs), allocation roles, functional variants, variable and behavior references to ensure consistent interactions between IEDs and functions.
• Engineering process guidance: Rules for creating, managing and editing BAP templates, addressing namespace conflicts, and requirements for conformance checking of files.
• Examples and use cases: Informative annexes provide BAP examples such as reverse blocking (distributed automation), condition monitoring for on-load tap changers, and line distance protection - covering logical architecture, data models, communication services and performance requirements.
• Traceability & tool support: Introduction of the Concept Definition Tool (CDT) and requirements for tools to manage templates, instances and namespace issues.

Practical Applications and Who Uses It

This Technical Report is intended for:

• Utility engineers and substation automation architects who need standardized application profiles for system design and commissioning.
• IED vendors and software tool vendors implementing IEC 61850 capabilities and SCL support.
• Systems integrators and testing laboratories building interoperable solutions or specifying acceptance tests.
• Project managers and standards specialists aligning engineering processes with IEC 61850-based interoperability requirements.

Practical uses include defining reusable application templates for protection, control, and condition monitoring functions, automating engineering workflows through SCL templates, and reducing integration risk by providing a common, machine-readable description of function behavior.
