摘要(Abstract):
在智能变电站中,时间同步系统为全站智能设备提供一个准确、安全、可靠的时钟源。通过对智能变电站的时间同步系统进行深入分析,总结出时间同步系统异常对智能变电站的站控层、间隔层和过程层设备的影响,为智能变电站时间同步系统的异常处理提供参考。
In intelligent substations, time synchronization system provides an accurate, safe, reliable clock source for all intelligent equipment. Through in-depth analysis on time synchronization system of intelligent substation, the paper summarizes the influence of abnormal time synchronization system on equipment of the substation control layer, bay layer and process layer in intelligent substation, providing reference for eliminating abnormity in time synchronization system of intelligent substation.
