substations, and various protective and control devices that communicate over communications networks. Typical utility terminology is a “low latency network” in the context of specific grid use cases and Define what “realtime” means applications. Real-time behavior of Ethernet based communication networks is defined in IEC 61784-2. There are 6 (plus one technology specific) consistent sets of parameters described to define the requested and achieved Real-time Ethernet behavior of end-to-end stations. For the network components using TSN is an effort ongoing in IEC SC 65C.PT61784-6, dealing with a TSN profile for industrial automation applications. Teleprotection differential protection schemes require very low (<10ms) – end to end latency, which must be highly consistent and predictable. Teleprotection differential protection schemes require very low (<10mS) end to – end latency, which must be highly consistent and predictable. Type of connection typically fiber – Intra-substation LAN. Support for IEC 61850 Generic Object Oriented Substation Event (GOOSE) messages for controlling relays and switches within the substation. TR61850-90-13 addresses this Type of connection typically Ethernet (copper or fiber) – GOOSE and MMS traffic. TSN could be a help on the process bus - Shared IT/OT networks over a common medium. The OT networks require a controlled, predictable latency, and freedom from dropped or lost packets. This behavior is required regardless of the loading or overloading of the IT network. How does TSN affect this? The important benefit is providing a converged architecture. Critical services can have guaranteed performance and bounded latency. This saves cost by converging several networks into one. But not all TSN behaviors can be built in one network component without a difficult engineering. A profile for Utilities is needed to reduce the effort of engineering. IEC TC57 is looking for such a profile and is collaborating with the IEC SC65C/MT9.PT61784-6 project team.
