Engineering analysis takes an interactive view

摘要

V-GRAPH, a one-line diagram and database program described in this article, is a Windows-based graphical interface to a comprehensive power system database. The database is common to individual power system modeling programs. Users need not enter data for separate applications. The capabilities of this graphical interface, which include one-line diagram drawing, data entry via click-on devices, database storage and graphical display of engineering analysis results, are attuned to the current trend towards visual data entry. The program runs under Microsoft Windows Version 3.1 and higher, on IBM-PCs or compatibles, and requires a Windows compatible mouse.
