摘　　要：针对智能变电站高级应用需求,提供了一种基于电气间隔的变电站分层拓扑分析方法。结合一次主接线图中各设备的节点连接关系,将变电站一次设备按照"变压器(绕组)-母线-电气间隔"分层结构进行组织,包括对典型的3/2接线、内桥接线等接线方式的识别。在此基础上实现了厂站主接线图中一次设备的静态拓扑识别和动态连通判断,从而有力支撑了智能变电站故障诊断、状态估计和电气间隔运行状态分析等站级智能高级应用功能。With respect to advanced application requirement of smart substations, a hierarchical topology analysis method was proposed for substations based on electrical separation. Based on the node connection relationship of each device in the primary wiring diagram, primary devices of the substation were organized in the principle of hierarchical structure of "transformer (winding)-bus-electrical separation". Typical 3/2 connection and internal bridge connection would also be recognized. On this basis, static topology identification and dynamic connection judgment were realized for the primary equipment in the main wiring diagram of the substation, as a powerful support of advanced application functions at the station level such as fault diagnosis, state estimation and electrical separation operation status analysis.
