Annotation of standard text IEC 61850-4-ed.2.1+Amd.1-CSV :

IEC 61850-4:2011+A1:2020 applies to projects associated with process near automation systems of power utilities (UAS, utility automation system), like e.g. substation automation systems (SAS). It defines the system and project management for UAS systems with communication between intelligent electronic devices (IEDs) in the substation respective plant and the related system requirements. This second edition constitutes a technical revision to align the document more closely with the other parts of the IEC 61850 series, in addition to enlarging the scope from substation automation systems to all utility automation systems. 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. This publication is of core relevance for Smart Grid.
