Draft TR IEC 61850-7-6 published: Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850

IEC TC 57 just published the 68 page draft Technical Report IEC 61850-7-6:


Communication networks and systems for power utility automation –
Part 7-6: Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850

Voting closes 2018-06-08.

"The IEC 61850 standard series offers a broad basis for communication networks and systems in power utility automation. Due to its broad coverage of power utility automation applications, it is up to the standard’s user (utility, vendor, system integrator…) to pick and choose specific options from the standard in order to meet the requirements of the intended objective. As a consequence, implementations of IEC 61850 represent specific subsets of the standard.
In the context of standards the term “profile” is commonly used to describe a subset of an entity (e.g. standard, model, rules).
Accordingly an IEC 61850 standard profile contain a selection of data models (mandatory elements), communication services applicable and relevant engineering conventions (based on the Substation Configuration Language SCL defined in IEC 61850-6) for an application function of a specific use case in the domain of power utility automation.
Depending on the scope and objective different profile types can be distinguished:

  • User profile – defined subset that is valid for a specific user / organization (e.g. utility)
  • Product / Device profile – implemented subset in a specific vendor product /device
  • Domain profile – defined subset for a specific domain and relevant use cases (e.g. monitoring of substation)
  • Application / function profile - subset covering a specific application or function (e.g. substation interlocking)

These profile types target on reducing complexity and facilitate interoperability for their specific scope and during engineering and device / substation lifetime. In order to achieve both these goals - a properly defined profile and appropriate implementations (processes, tools, products) that support the profile are required."

Note that IEC 61850 is not that complex - but it is very comprehensive!!
Comprehensiveness with regard to:

  1. Number of parts: some 50 inclusing drafts
  2. Number of Logical Nodes
  3. Number of Data Objects
  4. Configuration language
  5. Number of task forces working on new stuff
  6. Number of applications that can be covered
  7. ...

The most crucial challenge is this: How can I find what may be of interest for my application? I hope somebody will do a good job in preparing an overview of models published and under preparation.
Let me know if you are aware of some good document or website ...
