Time Sensitive Networking (TSN)
for IEC 61850 Substation Networks
Maik G. Seewald, maseewal@cisco.com, Member of IEC TC57 WG10
Patrick Wetterwald, pwetterw@cisco.com, Member of IEC TC57 WG10
Sed Introduction to TSN
Technical Background
= Determinism (Simplified: creation of a predictable system that always create the
same output)
= In Networking, the following objectives must be met: Bounded Jitter, Bounded
Latency, Very low packet loss ratio
= Technically, a fully scheduled network based on: Time Synchronization,
Resource reservation, Redundancy
= TSN is a set of technologies to achieve determinism in networking
= Determinism and the Industrial Ethernet are building blocks to enable
Industrial loT / Digital Factory / Industry 4.0

One (1) tool to manage the installation: IED’s
and Network Devices
Engineering-Tool programs the network with
“intent”
Only one protection and control expert
needed to configure and engineer the
substation automation solution
Engineering-Tool communicates with
controller
Controller programs network and
schedules the flows
Enhanced usability, less error prone
» Q&A
Discussion with Process Bus User Task Force
» We are very interested in your feedback!
= ... and in even more use cases:
= Use cases in grid automation that require deterministic delay and jitter
= Use cases in grid automation that benefit from deterministic and time
sensitive/scheduling capabilities (e.g.: multi-service/converged networking)
