The adoption of IEC 61850 in the deployment of Substation Automation System opens new scenarios to system design. The presence of a communication infrastructure connecting Intelligent Electronic Device (IED), sensors and protections may suggest the development of distribute measurement devices, where the sampling of the physical quantities and the elaboration of the sampled value could be performed...
The modern industrial and substation automation Ethernet networks have demanding requirements about high availability. Recently, the IEEE 802.1 WG proposes the IEEE 802.1aq, also known as Shortest Path Bridging, to manage Ethernet redundant networks. The IEEE 1588 protocol can exploit the SPB capabilities to manage multiple paths in order to improve synchronization availability. In the paper, the...
The introduction of the standard IEC 61850 for the communication of Substation Automation System (SAS) opens new scenarios in which products of different vendors can communicate on the same network infrastructure, based on Ethernet technology. The recent improvements in industrial communications are going to deeply influence two of the key points in the development of SAS: synchronization and availability...
