智能变电站合并单元同步方法研究

Research on Synchronization Method of Merging Unit in Smart Substation

基于合并单元同步性能与数据可靠性,分析同步元件的工作状态机制,提出同步守时方法。在分析合并单元同步元件工作状态机制与状态判断的基础上,研究了外部时钟丢失后合并单元误同步机理,并提出了相应的改进方法,以避免误同步的发生。

Based on the synchronization performance and data reliability of the merging unit, the working mechanism of the synchronization element was analyzed and the synchronization timing method was proposed. On the basis of analyzing the working mechanism and state judgment of the synchronizing element of the merging unit, the mechanism of the incorrect synchronization of the merging unit after the loss of the external clock was studied. The corresponding improvement method was put forward to avoid the occurrence of the incorrect synchronization.
