摘　　要：介绍了一种基于公共信息模型(CIM)/可扩展置标语言(XML)电网模型和可缩放矢量图形(SVG),以及以联络线路为边界进行多区域电网模型在线拼接与合并的方法。针对各区域系统之间存在T接联络线的情形,提出通过T接分组的方式来解决由于虚拟站命名不统一而造成的T接点不易合并,以及线路信息频繁修改等问题。在模型的增量更新上,除了通过设备的统一命名来更新设备参数外,还通过运行库与待导入模型文件间的连接关系绑定实现模型连接关系的增量更新。通过模型的在线拼接与合并,所开发的电力保障自动化系统根据电网拓扑梳理出从380V到上级各级电源的供电路径,满足了"全链条式"的电网监视要求,最大限度地保障了对重要用户的可靠供电。A description is made of an online multi-regional model splicing and merging method based on the CIM/XML power system models and SVG graphs and with the tie lines as modeling boundaries for the power ensured automation system. In view of the teed tie lines between regional systems, tee grouping is presented to merge the tee connections from several-models and prevent frequent modification of the line information due to non-unified naming of virtual substations. As for the incremental model update, apart from updating the attributes of devices on the basis of unified naming, the connection between equipments will be updated by binding the connectivity of the operating system to that of the model to be imported. By means of the model＇s online splicing and merging, the power： ensured automation system developed will be capable of retrieving a power supply path for important customers from 380 V to all upper level power sources through the network topology. Thus the requirement of ＂the whole .chain＂ network monitoring can be met, guaranteeing as much as possible＇ reliable power supply to important customers.
