Time-Sensitive Networking is the next big thing in automation and control networks, especially in the context of IEC 61850: Deterministic Networking technologies based on the standards from IEEE 802.1TSN provide various means to support substation automation networks based on IEC 61850. Higher efficiency in terms of resource usage is only one benefit. In many deployments, substation network bandwidth is overprovisioned in order to achieve the delay and packet loss requirements. Combined with the benefits of guaranteed bounded latency, low bounded jitter, and low packet loss, a substation automation solution built on top of an IEC 61850-TSN -Profile is a good fit to meet the tight requirements in an efficient way. As one result, the adoption and implementation of the Process Bus as a key architectural component of IEC 61850 would benefit.
