IEC 61850 defines two types of specific communication service mapping (SCSM) for sampled values communication among intelligent electronic devices (IED): sampled values over serial unidirectional multi-drop point to point link in IEC 61850-9-1and sampled values over ISO/IEC 8802-3 in IEC 62850-9-2. In view of the importance of real-time communication, packet transfer model was built following IEC...
This paper describes the experience from the world first installation of High Voltage substation with IEC 61850 Process Bus where IEEE 1588 Time Synchronization and dynamic multicast filtering have been used. The authors provide brief introduction to the concept of digital substation and process bus, then provide overview of IEEE 1588 standard for precise time synchronization and finally describe...
There is a need for fool proof architecture of the substation communication network (SCN) for reliable, fast and deterministic operation of the automation functions within a substation, to ensure the reliability, availability and survivability of the geographically distributed complex power network. This paper presents different types of Substation Communication Network architectures and analyzes...
