Using IEC 61850 data transfer beyond the substation for enhanced protection for distribution networks

摘要: Protecting electricity distribution networks is becoming increasingly challenging and improved performance continually being demanded. The growth in distributed generation, the opportunities offered by meshed service demands of consumers require smarter protection. Invariably, solution will involve capitalizing on developments digital relaying communications. This paper describes findings an investigation into extending concepts communications within substation contained IEC61850 beyond order to provide It introduces basis for Fault Passage Relaying current differential protecting feeders associated internet scheme. based scheme builds behind provides a process bus.
