Abstract

According to the intelligent substation and the increasing synchronization requirements of Green Power Grid, it is important to establish a communication support network of time synchronization in the whole power grid. This paper offers a comprehensive introduction and detailed analysis of the basic concept, signal type and the networking technology of time synchronization. According to the application requirements of power system in Yunnan Power Grid and the characteristics of power communication network, the DCLS +NTP time synchronization networking mode based on SDH+IP network, the NTP time synchronization networking mode based on IP network, the PTP time synchronization networking mode based on SDH +IP network and the PTP time synchronization networking mode based on PTN+OTN in future are investigated , they will be the reference of time synchronization network formation in Yunnan Power Grid.
