【摘要】The high precision time synchronization principle based on IEEE 1588 is introduced in this paper, and the organizational structure of the PTP synchronization system for digital substation is described~ This paper studied best master clock algorithm, local clock synchronization algorithm and introduced the production of the hardware timestamp. The factors which affect the accuracy of clock synchronization have been analyzed. The accuracy of clock synchronization have been tested in the last. It can meet the accuracy requirements of all the levels of IEC 61850.%介绍了基于IEEE1588协议的高精度时间同步原理,描述了数字化变电站PTP同步对时系统组织结构。研究了P1’P的最佳主时钟算法、本地时钟同步算法及硬件时间戳的实现,分析了影响同步性能的因素。最后对时钟同步精度进行了测试,结果表明可满足IEC61850所有等级的对时精度要求。 【总页数】4页(71-73,77)
