摘要：传统的对时方式已经不能满足目前变电站对于对时精度的要求。本文通过对脉冲对时、编码对时和网络对时等几种同步对时技术进行研究,对其对时精度、组网方式等进行了比较,同时根据数字变电站站控层、间隔层和过程层的对时可靠性及精度的要求差异,综合考虑建设成本、日常维护等因素,提出了SNTP+IEEE1588网络同步方案,并指出了变电站同步对时技术的发展趋势。
At present, the traditional synchronization technology can ’t meet the substation’s requirement for synchro-nization precision.This paper studied the time synchronization technology such as pulse synchronization , coding time and network time synchronization , and compared their time precision and network mode.And meanwhile according to the different requirements for the synchronization reliability and precision of station level , bay level and process level of the digital substation and considering the construction cost , daily maintenance and other factors , this paper pro-posed the SNTP ＋IEEE1588 network synchronization scheme , and pointed out the development trend of the substation time synchronization technology.
