摘　　要：介绍了智能变电站现阶段采样值系统两种主要应用模式,结合江西电网已投运智能变电站采样值系统应用情况,归纳总结了两种模式普遍存在的主要问题,并提出了针对性的解决措施。分析了采样值系统主要两种数据同步方案——基于插值算法的软件自同步和基于同步源的硬件同步应用及优缺点。Two main application modes of the smart substation sample value system are introduced according to sampling value operation of smart substation system. Moreover, the Common problem of two modes is summarized. And some corresponding measures are put forward. Finally, software synchronization based on interpolation algorithm and hardware synchronization based on synchronous resource are analyzed.
