On the basis of building a data model for synchronization devices and clock links to simulate the timing link transmissions of synchronization networks

quantitative analysis data can be obtained for the optimization and expansion of the existing sync networks.Using the simulation software independently developed by the Electric Power Research Institute of China

this paper analyzes the adaptability of the State Grid 1st-level backbone network structure to the clock synchronization and the clock state of the network nodes and links after clock optimization and adjustment

calculates the statistical results of the ultra-long link phase errors and detects the erroneous clock setting

providing forceful data support for the planning and construction of synchronization networks.
