The research of power system has been paid more and more attention
in the current society. How to achieve the efficiency of power distribution and the
transformation of lines are the most critical part of this research. Through a series of
research methods and line technology transformation, the power system is constantly
optimized. In this paper, a SDH based network architecture system is proposed. The
system is based on the most rapid and mature SDH network in the power system
research as a fixed medium of the network structure system. Its method is to use the
time slot calibration network architecture (TSA) algorithm for time calibration, which
can achieve high-precision synchronization of the system, and then reconstruct the
power line. Next, we will discuss the transformation of power lines based on SDH
network structure in power system.
