摘　　要：随着电力系统规模的扩大以及电力系统控制技术的发展,时间同步变得越来越重要。NTP网络授时服务作为电力系统时间同步中一项重要的方式。因此,设计一个高精度的NTP服务器为电力系统提供授时服务是十分重要的。本文以AT91RM9200处理器为硬件核心,嵌入式Linux系统为软件核心,设计了电力系统NTP授时服务器。经试验证明,授时精度高,系统运行稳定。In recent years, with the expansion of power system and the development of power system control technology, Time synchronization is becoming more and more important. The NTP network time synchronization services become more and more important as an important way of electric power system. So designing a high precision NTP server for power system to provide the timing services is very important. Based on AT91RM9200 processor as the core hardware, software embedded Linux system as the core software,the author designed NTP time synchronism syetem of power system. Through the experiment, the timing Synchronism precision is high, the system runs stably.
