Title Communication networks and systems for power utility automation - Part 4: System and project management
Project Number 22715
Abstract/Scope IEC 61850-4:2011 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 publication is of core relevance for Smart Grid.
