Abstract

High precision and high reliable time transmission network and time signal transmission technology are the key of time network of power grid.This paper analyses the demand of power grid on time transmission,the characteristics of SDH optical transmission and high-precision time transmission technology.It discusses the time transmission technology based on the two-way pulse method with adaptive compensation,E1 channel coding techniques and location measurement techniques,theoretically analyses the leading causes of time transmission error,and put forward an analysis on test data. The key technology applied in the process of time transmission is also introduced in the paper.
