AN OBJECT-ORIENTED POWER-SYSTEM GRAPHICS PACKAGE FOR PERSONAL-COMPUTER ENVIRONMENT

Power system graphics package (PSGP) is developed and presented in thi s paper. This new package runs on a personal computer along with Micro soft Windows and ToolBook software packages. The chief advantage of PS GP is featured by its capability to combine texts and graphics into on e package for power system analysis, design and education. PSGP contai ns extensive color graphics representations of power systems, interfac e with external power system simulation programs, dynamic display of t he simulation results and communication among external and internal da ta bases. In addition, a PSGP user can edit large blocks of informatio n using basic commands such as cut, copy, paste and clear. PSGP applic ations in power systems are illustrated by a few examples in this pape r. The minimum system requirements, as well as the PSGP implementation and its specific features are discussed.
