In order to implement the system configuration function based on IEC61850and strengthen the description for virtual interactive messages among protection intelligent electronic devices（IEDs），a kind of prototype of graphic system configuration tool based on IEC61850for substation is studied.Function modules of the system include the main user interface，extensible markup language（XML）analysis and substation configuration language（SCL）syntax verifying modules，as well as three kinds of interactive information configuration modules，i.e.，internal protection logic relationship in a logical node（LN），the coordination logic relationship among LNs in an IED，the virtual interactive messages among LNs of different IEDs.Some toolboxes that include primary electric wiring diagram and secondary equipment configuration are designed.Implementation methods of the key techniques are described，such as drawing and picking of graphic elements，the storage of graphic files with scalable vector graphics（SVG），the graphic configuration of the virtual interactive messages among different IEDs.The main function of prototype graphic configuration system has been implemented.It provides a reference for the configuration development and system testing of intelligent substation.
