| Abstract: | The definitions given by IEC 61850 on logical nodes (LNs), PICOM, event time, transfer time, types and performance classes of message are expounded. The requirement of the performance of messages for substation automation systems, the standard IED synchronization and the indices of related values of power system, e.g., the accuracy, harmonic, resolution and sampling rate of voltage and current for different classes are put forward. |
