IEC 61850 facilitates communications within substations automation systems.
IEC 61850 is more than a simple protocol standard. It is object oriented and models for communications between devices and user-friendly names in the context of a standard power system.
It utilised efficient networking technology including TCP/IP networks as well as substation local area networks. This is done using high-speed Ethernet, which enables the swift response necessary to monitor protective relays.
This also enables redundancy options and time synchronisation for system-wide time-coherent data.
