电网卫星驯服时钟的网络时间同步服务器设计

Design of Network Time Synchronization System Based on Network Satellite Disciplined Clock

在分析网络时间同步协议的基础上,设计了一种ARM+FPGA的网络时间同步服务器。研究了用卫星驯服时钟的方法解决了网络时间服务器中时钟源精度不高,易受干扰的特点,采用了PI调节器的时钟驯服模型。通过实验测试,该服务器可满足对电力系统二次设备的同步授时。

In this paper,the design of an ARM ＋ FPGA for network time synchronization server analysed the network time synchronization protocol.Researching use satellite clock solution to tame a network time server,tackled clock accuracy is not high and susceptible to interference characteristics,using PI regulator clock model Experimental results of the server can satisfy the power system synchronous timing of secondary equipment.
