摘要(Abstract)：
在智能变电站中,网络采样模式下的对时系统对时策略以及过程层设备合并单元的数据同步机制起着重要作用。对时系统异常情况下对合并单元的影响,以及合并单元对异常对时系统的处理机制都决定了数据同步的准确性。针对采样同步对时系统和合并单元的对时策略进行探讨,分析多种可能发生的异常对时情况及由此导致伪同步现象,给出了对时系统应对策略和合并单元的同步机制。
In intelligent substation,the strategy of time synchronization system in network sampling mode and data synchronization mechanism of merging unit of process layer equipment play an important role. The influence of time synchronization system abnormity on merging unit and influence of merging unit on the processing mechanism of abnormal system decide data synchronization accuracy. The paper discusses synchronization strategy of synchronization system and merging unit on the basis of sampling synchronization and analyzes various potential synchronization abnormities and the consequential pseudo-synchronization; moreover,it presents strategy of time synchronization system and synchronization mechanism of merging unit.
