Abstract

Abstract: In order to assist speedy design of virtual terminals in SCD, a graphical generation method and system for virtual terminals in intelligent substation are studied. Some key technologies are described, including manual rapid association, template-based search for output terminals and copy virtual connections to similar objective devices. The virtual input terminals are displayed graphically with multiple partitions and columns, as well as output terminals and their sending sources. With dragging and dropping technology, the output virtual terminal is designated to corresponding input virtual terminal. For an input terminals, with the virtual connections from SCD templates, the similar candidate terminals can be found by matching virtual terminals description and keywords to generate virtual connections for objective device. The graphic generation system has been implemented by Qt C++. It has been applied to actual substation design and improved design efficiency and accuracy.

Key words: intelligent substation, SCD, design of virtual terminal, graphic interface
