摘要
介绍了时间同步的概念和主要方式,简要描述了PTP网络对时协议的同步过程,针对目前时间同步存在的问题,分析论证了建设全省时间同步网的必要性和意义;同时结合山东电力传输网现状及发展趋势,展望了基于地面链路的山东电力时间同步网建设与应用,可作为山东电力PTP时间同步网建设的参考依据。
This paper introduces the basic concept and main mode of the time synchronization,describes the synchronization process of PTP network based on precision time protocol,and analyses the necessity and significance of constructing a provincial time synchronization network.Combining existing situation and developing trends,it discusses the construction and application of Shandong power time synchronization network based on ground links.It has reference value for the construction of PTP time synchronization network in Shandong power grid.
