| Abstract: | In order to satisfy the high precision and high security requirements of time synchronization for Smart Grids,a time synchronization system is proposed in this paper,which is based on the Bei-Dou/GPS dual-mode timing and IEEE 1588 protocol.According to different operation modes of the system,different time synchronization schemes are presented for master stations and sub-stations.And their time synchronization errors are discussed,the closed loop control method of crystals compensation is also proposed,the efficiency and precision of the time synchronization are improved. |
