This paper describes the experience from the world first installation of Smart High Voltage substation with IEC 61850 Process Bus where IEEE 1588 Time Synchronization and dynamic multicast filtering have been used. IEC 61850 is one the 30 standards identified by NIST as key elements for achieving interoperability in the Smart Grid. This paper describes the experience from a high voltage substation...
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...
Modern distance protection relays are complex multifunctional devices based on classical or advanced operating principles that impose special requirements for their testing. The paper analyzes the functionality, the functional hierarchy and the schemes typically available in distance relays. It then discusses the methodology for testing of such relays. Testing of individual protection and non-protection...
The Architecture of Substation Secondary Systems (AS3) [6] is a project within National Grid Electricity Transmission which is seeking to overcome some of the ownership challenges presented by modern protection and control (P&C) devices, which have an inherent short life due to their dependence on modern electronics and software. This will be achieved by implementation of a process bus using IEC...
This paper presents a practical process bus architecture conforming to IEC 61850-9-2 that fits the task of protection and control of substations by drawing from the universal topology rules of substations.
IEC 61850 is the new standard for communications in substations that defines process bus and substation bus communications allowing the development of distributed waveform recording systems. The paper describes the different components of such systems and the distribution of functions between the devices included in it. Multiple merging units communicate over a 100 Mb Ethernet with a central computer...
