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.
