摘　　要：介绍了PTP授时原理,分析了智能变电站PTP授时服务器的架构,提出通过精简PTP服务器状态机和采用集群PTP来提高授时服务的可靠性、可用性和可扩展性,并提出了安全PTP服务的构建思路和快速跟踪外部时间源,这对构建智能变电站统一坚强的网络授时服务平台具有一定的指导意义。This paper puts forward the ideas of refining PTP server state machine to improve the stability and using clustering PTP service architecture to improve the availability and scalability. A safe PTP service model and a fast external time source tracking mechanism are also discussed in the paper. It has reference value for the construction ofunified time service platform in smart substations.
