| Abstract: | According to the intelligent substation building program and the synchronization requirements of the power automation system in the smart grid, the synchronization modes of power automation system were analyzed and compared. A method of utilizing SDH network to achieve IEEE 1588 Precision Time Protocol （PTP） is proposed. The new synchronization system is based on SDH transmission terrestrial links, so both satellite and ground synchronization signal are provided and both are each other＇s back. The proposed method achieves communication synchronization and electric power automation synchronization system integration. The prospects of entire power system networks PTP synchronization are also forcasted. |
