The purpose of PowerGraf is to present a graphical user interface (GUI) and a convenient tool for building one-line diagrams displaying data. The GUI is open and friendly for power systems design, analysis and control, because a picture provides a better illustration of cause-and-effect relationships than a tabular printout does. Basic elements such as buses, lines and transformers are given such that the power system topology is easily drawn with this tool, and the system parameters are entered on the picture and checked visually. This enables the power system topology and the system data to be shown on one picture page. The advantages of these graphics are that users can view line overloads, low voltage problems, and outages on the overall(total) system. In addition, it is possible to see the impact of contingencies on the system. To date, PowerGraf 3.0 together with an instructional demo has been used to teach power systems courses in Electrical Engineering Department at the University of Missouri-Rolla (UM-Rolla). It is also available on the Computer Learning Center network to help students design their own optimal power systems. © 1997 IEEE.
