Construction Scheme of Integrated Timing and Clock Synchronization System in Power Grid

电网一体化时间同步网的建设方案,主要是基于现有数字同步网和变电站时间同步系统,采用IEEE1588v2精确时间同步协议(PTP)传输时间同步信息,并在卫星同步源方面增加北斗同步系统,实现时间同步源的GPS、北斗和地面同步网天地互备格局,大大地提高电网时间同步可靠性的同时,实现全网同步。

The Power Grid integration time synchronization network construction scheme is mainly based on the existing digital synchronous network and substation time synchronous system,using IEEE 1588v2 precise time synchronization protocol（PTP） transmission time synchronization information,and the BD synchronization system to be used for the time synchronization source beside GPS.Thus the time synchronization sources of satellites（GPS and BD） and time network are prepared each other,which will improve the time synchronization and reliability greatly at the same time,the whole network synchronization in Power Grid is relized.
