This part of IEC 61850 applies to projects associated with process near automation systems 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. The specifications of this part pertain to the system and project management with respect to: - the engineering process and its supporting tools; - the life cycle of the overall system and its IEDs; - the quality assurance beginning with the development stage and ending with discontinuation and decommissioning of the UAS and its IEDs. The requirements of the system and project management process and of special supporting tools for engineering and testing are described.
