Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850

IEC TC 57 has published a document for comments (57/1813/DC, 27 pages) on application profiles::

Draft IEC TR 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

Comments are expected by 2017-02-03

This guideline is focused on building Application / function profiles and specifies a methodology to define Basic Application profiles (BAPs). These Basic Application profiles shall provide a framework for interoperable interaction within or between typical substation automation functions. BAPs are intended to define a subset of mandatory features of IEC 61850 in order to increase interoperability in practical applications.

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
A nice example is contained in Annex A:
