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...
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...
This paper deals with time synchronization of distributed systems over Industrial Ethernet network. A new simulation model of IEEE1588 PTP is presented and discussed. The development platform used for simulation is OPNETtrade. Architecture of the proposed model is explained in details, highlighting some special features introduced by authors: modelization of drift and rate variations in the local...
