Development of intelligent grid have increasing demands for time synchronization, high precision, large scale, high performance time synchronization system has become necessary guarantee for the normal operation of the power grid. This article introduced the composition of the time synchronization system, discusses the IEEE1588 implementation of high precision clock synchronization principle and SDH data transmission principle, analysis of the PTP protocol for transmission through the principle of the SDH E1 line, gives the networking scheme of PTP over the E1 way, which meet the precision requirement of 1 us.

High performance clock synchronization system is essential in communication transmission, which is based on the principle of phase locked loop synchronization that tracking a high accuracy, high stability reference clock source usinh low-pass filter to turn the value into voltage and to control VCO or VXCO and makes the output frequency and the input frequency to maintain strict synchronization.

Modern high-speed telecommunication networks with time division multiplexing (TDM) based on nx64kBit/s channel switching cannot function without a high-quality network synchronization system, which is designed to ensure the reliability and stability of the formation, switching and processing of information in digital channels. The clock synchronization system is based on the transmission of the reference frequency from the primary clock to all digital equipment of the telecommunication network through the high-speed streams of transmission systems. However, in the case of distributed communication networks, the integrity of the clock synchronization system is violated, and there is a need to develop special technical solutions to ensure the provision of frequencies for all remote network elements. This article is devoted to an overview of such solutions.
