This part of IEC 61850 applies to substation automation systems (SAS). It defines the com-munication between intelligent electronic devices (IEDs) in the substation 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 discon-tinuation and decommissioning of the SAS and its IEDs.
The requirements of the system and project management process and of special supporting tools for engineering and testing are described.
