Communication networks and systems for power utility automation - Part 7-1: Basic communication structure - Principles and models

IEC 61850-7-1:2011+A1:2020 introduces the modelling methods, communication principles, and information models that are used in the various parts of the IEC 61850-7 series.

The purpose is to provide - from a conceptual point of view - assistance to understand the basic modelling concepts and description methods for:

  • substation-specific information models for power utility automation systems,
  • device functions used for power utility automation purposes, and
  • communication systems to provide interoperability within power utility facilities.

Compared to the first edition, this second edition introduces:

  • the model for statistical and historical statistical data,
  • the concepts of proxies, gateways, LD hierarchy and LN inputs,
  • the model for time synchronisation,
  • the concepts behind different testing facilities,
  • the extended logging function.

It also clarifies certain items.

This consolidated version consists of the second edition (2011) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
