摘要
阐述了IEC 61850对逻辑节点、通信信息片、事件时间、传输时间、报文的类型和性能级的定义。并指出了变电站自动化系统中报文的性能要求,IED同步标准及电力系统有关参量的指标(如电压、电流对不同级别的精确度、谐波、分辨度和采样率)等。
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.
