Abstract

The application of IEEE1588 in time synchronizing system of smart distribution grid is researched in this paper. Topologic structure of communication system of distribution grid is analysed in the second instance. Redundancy configuration and auto-select technique of precise clock source are brought forward afterwards. Thirdly, clock mode selection scheme of backbone layer, access layer and distribution terminal are analysed with emphasis. Finally, IEEE1588 synchronization process in the redundant mechanism of backbone layer, access layer and distribution terminal is presented in detail.
