北斗、GPS卫星授时在电力系统时间同步装置中的应用

The Application of Beidou and GPS Satellite Timing in Power System Time Synchronizers

电力系统时间同步装置在维持电力系统正常运行控制、事故分析等方面起着极其重要的作用。对北斗、GPS卫星导航系统进行介绍的同时进行差异对比,阐述了卫星授时机理;探讨了卫星授时技术在电力系统中的应用。采用北斗加GPS双时源卫星授时的时间同步装置成为当前电力系统时间同步的主流方案。

Time synchronizers are of vital importance in maintaining normal operational control and accident analysis of power systems.This paper outlines satellite navigation systems such as Beidou and GPS,makes a comparison between the two,explicates the mechanism of satellite timing,and discusses the application of satellite timing technology in power systems.It can be concluded from the review that time synchronizers supported by Beidou and GPS dual-source satellite timing has currently become prevailing solution in power system time synchronization.
