A personal computer graphical environment for industrialdistribution system education, design, and analysis

摘要

The purpose of this paper is to investigate the computernapplications and analyses in industrial distribution design. First ofnall, we have to inquire into the design of graphic symbols and thendrawing of a single-line diagram by taking advantage of AutoCADnsoftware. Next, by employing DBASE III, the database for distributionnapparatus is accomplished to integrate with the graphic information sonthat the distribution graphic information database is obtained. Then, wenfocus our attention on the applications of practical operation for anfactory. Written in C language, the application programs include loadnflow calculation, voltage drop equation, grounding resistor selection,npower factor improvement, wire selection, protective coordinationndisplay, and fault current computation. Finally, the linking ofnman-machine-interface and application programs can be accomplishednthrough the modification of ACAD.MNU and ACAD.PGP of AutoCAD.nAccordingly, an educational teaching software is developed to carry outna key-controlled industrial distribution system analysis
