| Abstract: | 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. |
