摘要
电网内各节点的时间同步对于电网中各厂站的事故分析有重要作用,文章阐述利用SDH网络、IEEE1588协议以及铷钟等技术研发的电网时间同步系统,实现在GPS、北斗等无线信号以及厂站间有线链路出现问题时仍能保证厂站时间精准同步的方法,为今后时间同步系统的建设和应用提出建议。
In the power grid, the time synchronization of each node plays an important role in the accident analysis of each station. This paper describes the power grid time synchronization system with SDH network, IEEE 1588 protocol and rubidium clock and other technologies. This paper implements a method that ensured station time accurate synchronization when the wireless signal of GPS and Beidou, the plant station wire link appeared problems. It makes suggestions for construction and application of future time synchronization system.
