电力系统GPS同步授时装置设计与应用

Design and Application of Power System GPS Synchronous Clock Device

设计了一种基于STC 12C5A32S2单片机的电力系统GPS同步授时时钟,并介绍了其工作原理;该GPS同步时钟与备用时钟一起为整个电力系统提供精确的时间信息,一分钟内可以完成定位,授时精度在微秒级;不仅具有较高的可靠性和实用性,而且能够满足电力系统对GPS授时的要求;最后对GPS同步时钟在电力系统自动化中输电线路行波故障测距、GPS的同步相量测量技术等功能中的应用进行了讨论。

This paper designed a synchronization based on STC12CSA32S2 micro--controller power system GPS timing clock, and describes how it works. GPS synchronized clock and standby clock provide accurate time information for the entire power system. It not only has high reliability and practicality, but also to meet the requirements of the power system on the GPS timing. Finally, the application of GPS--synchronized clock in the transmission line traveling wave fault location, the GPS synchronized phasor measurement technology are discussed.
