This standard defines communication delivery time of information to be exchanged within and external to substation integrated protection, control, and data acquisition systems.
Utilities will use communication performance requirements as part of a procurement specification to develop new substation automation systems, or to modify existing substation automation systems. Vendors will use communication performance requirements to build open system communication interfaces for intelligent electronic devices for substation automation.
New IEEE Standard – Inactive-Reserved. A standard defining communication delivery times of information to be exchanged within and external to substation integrated protection, control, and data acquisition systems is described. Communication capabilities and system capabilities to deliver data on time are also specified.
