Abstract

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.
