1 概述 随着电力系统自动化技术的发展,系统对时间统一的要求日趋迫切,对时间同步精度的要求也越来越高,我们选用进口GPS接收机部件二次开发研制而成的GPS—1标准时间同步钟,就是专门为电力系统自动化提供高精度时间基准的时间同步设备。该设备以美国导航星全球定位系统为时间基准,可以同时跟踪视场内的12颗GPS卫星,自动选择最佳星座进行定位、定时,其时间同步精度为1μs。
1 Overview With the development of power system automation technology, the system is more and more urgent requirements for time uniformity, the time synchronization accuracy requirements are getting higher and higher, we use imported GPS receiver components developed by the second developed GPS-1 standard Time synchronization clock, is specifically for the power system automation to provide high-precision time-based time synchronization equipment. The device to the United States navigation satellite global positioning system as a time base, you can simultaneously track 12 GPS satellites in the field of view, automatically select the best constellation positioning, timing, the time synchronization accuracy of 1μs.
