Communication networks and systems for power utility automation. Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850 | Status: Current

1 Scope

1.1 General

This part of IEC 61850, which is a Technical Report, is focused on building application / function profiles and specifies a methodology to define Basic Application Profiles (BAPs), in textual documents (edition 1, 2019) or in a machine processable SCL format (current edition). These Basic Application Profiles provide a framework for interoperable interaction within or between typical substation automation functions. BAPs are intended to define a subset of features of IEC 61850 in order to facilitate interoperability in a modular way in practical applications. It is the intention of this document to provide a common and generic way to describe the functional behavior of a specific application function in the domain of power utility automation systems as a common denominator of various possible interpretations/implementations of using IEC 61850. The guidelines in this document are based on the functional definitions of:

• • IEC 61850‑5 , Communication requirements for functions and device models, which gives a comprehensive overview of all application functions needed in a state-of-the-art substation automation implementation.
• • IEC TR 61850‑7‑500 , Basic information and communication structure – Use of logical nodes for modelling application functions and related concepts and guidelines for substations, which illustrates and explains application functions for the substation/protection domain of Logical Nodes in modelling simple and complex functions, to improve common understanding in modelling and data exchange, and finally to lead to interoperable implementations.
• • IEC TR 61850‑90‑3 , Using IEC 61850 for condition monitoring diagnosis and analysis, which gives use cases and data modelling for condition monitoring diagnosis and analysis functions for substation and power grid facilities.
• • IEC TR 61850‑90‑30 , IEC 61850 Function Modelling in SCL, which describes extensions of the SCL Substation/Process Section allowing to create a comprehensive, IED and hardware independent specification of an IEC 61850 based power system.

This document does not describe the applications and respective implementation requirements; the focus is on their typical information exchange including data and communication services and engineering conventions.
