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.
