Study on Clock Synchronization Model in Low Voltage Station

Abstract

At present, the requirements for smart and digital power grids continue to increase. As a unique communication method for power grids, power line communication has the advantages of low-cost and wide coverage. However, the low-voltage station topology is complicated and the clock synchronization problem needs to be solved urgently. This article first analyzes the low-voltage station area. The hierarchical structure of power line on-air communication, and then the clock synchronization Precision Time Protocol is studied. Finally, the modularization scheme of low-voltage power line carrier clock synchronization is designed, which is of great significance for improving the accuracy of low-voltage station power line carrier clock synchronization and reducing costs.
