摘要
Power GTS是通过电网现有的SDH光通信网络为主,以GPS或者北斗为补充的电网统一授时系统。文章从研发的角度出发介绍了Power GTS中区域时间中心系统的组成及其主要功能。通过已建立的Power GTS示范网的测试数据,说明这种授时网络的中心站可以保证20 ns的授时精度,而其传递到从站的时间精度可以达到微秒量级。
The power GTS is a time service system for power grid,which mainly through SDH optical communication network and implemented by GPS or BD.This paper introduces the system configuration and the main functions of the regional time service center of the power GTS system.Based on the test data from power GTS demonstration network,it points out that this time service network can ensure 20 ns timing accuracy.So the time accuracy at repeater stations can reach microsecond.
