Real-time networks for substations automation systems are based on ICT technologies and they may take great advantages from ultra recent network technological improvements. A careful evaluation of the performance enhancement is required. Due to cost and system complexity, such an analysis can be performed only using a dedicated simulation environment, but the currently available simulation libraries...
In modern real-time Ethernet networks for substation automation, several protocols are adopted to guarantee the strict synchronization and availability requirements imposed by applications. The management of these networks is more and more complex, since several (cross-influencing) configuration parameters affect the performance of the overall system. In this paper the attention has been focused on...
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...
In the last year the automation systems in power substation start to rely on networks thanks to the introduction of the IEC 61850 standard. Besides, it generates a general interest on synchronization also in the field of substation automation systems. In fact, timestamping of critical events or synchrophasor measurements can have a great advantage from distributed synchronization protocols like IEEE...
