摘要
分析了电力系统对时间同步的各种需求,介绍了一种新型北斗II代/GPS双模卫星导航接收模块,并以此为基础研制了一种电力系统双模时间同步时钟。研制的双模卫星导航接收模块支持北斗II代和全球定位系统(global positioning system,GPS)的单系统定位和双系统联合定位,对电力系统的安全稳定运行具有重大的战略意义。双模时间同步时钟输出信号类型包括RS232/485串行口、IRIG-B(inter-range instrumentation group-B)、脉冲以及网络时间协议(network time protocol,NTP)/PTP(precision time protocol),可为电力系统中各种自动化设备提供精确时间基准。
In this paper, the development trend of time synchronization system in the power system was analyzed, and a new Beidou II/GPS dual-mode satellite navigation receiving module was introduced developed, which leads to the development of a dual-mode synchronization clock for power system. The receiving module supports not only independent work mode of Beidou or GPS, but also unite work mode of Beidou and GPS. It has great strategic significance for the safety and stable of power system. The Time synchronization clock has multi output information format including RS232/485, inter-range instrumentation group-B （IRIG-B）, pulse and network time protocol （NTP）/precision time protocol （PTP）, which can be a precise time source for kinds of automation devices in the power system.
