| Abstract: | Based on the structure and function of digital substations,the time synchronization demands of intelligent electrical devices are analyzed in this paper.On this basis,a multi-level time synchronization scheme is proposed.In this scheme,the network synchronization technology based on SNTP and pulses per second(PPS) are used to realize the data synchronization and assure the functions of intelligent electrical devices.According to the requirement on synchronization scheme,the performance of SNTP synchronizati... |
