智能变电站配置描述虚端子多视角图形化查看系统

Multi-view Graphical Viewing System for Virtual Terminals in Smart Substation Configuration Description

为方便辅助设计人员与调试人员以不同的视角快速准确查看智能变电站配置描述(SCD)中各设备的虚端子及其连接关系,研究了多视角图形化查看方法。运用图形化技术,以宏观图直观显示每个智能电子设备(IED)与其各发送、接收设备之间的虚端子宏观联系。从2个IED之间的某组虚连接、某IED的全部输入(或全部输出)虚连接、某发送控制块详情等多个视角,展示各设备之间虚端子的关联关系。通过图形化操作实现宏观图与子图之间、多个IED之间的切换。目前,该系统已成功应用于多座智能变电站的系统调试,大幅提高了查看与检查设备虚端子的准确性及工作效率。

To facilitate rapid and accurate examination by design and testing people of the virtual terminals of substation configuration description(SCD)in smart substations,a kind of multi-view graphical viewing method is proposed alongside a multi-view graphical viewing system. Using the graphic displaying technology, a macro-graph is designed to show the macro-linking between each intelligent electronic device(IED)and its sending and receiving IEDs.Multiple subgraphs are given to show the details of virtual terminals,such as the virtual connections between two IEDs,all input and output virtual terminals of one IED and the detailed information on control block.The graphic switching technology between macro-graphs and subgraphs is studied.To date,the multi-view graphical viewing system of virtual terminals has been implemented and successfully applied to system testing of some substations,with greatly improved efficiency and accuracy of viewing virtual terminals in SCD.
