Abstract :
This paper presents the experimental study of advanced interactive power systems analysis using a-personal scientific computer. The personal scientific computer has new powerful displaying and operating capabilities. Our workstation, called the Advanced Analyzer of Power System (ADAPOS), intends to utilize these capabilities for power systems analysis. In addition our workstation has three features to perform effective human interaction: a supervisory system, database and graphic human interface. The supervisory system controls start and stop of application programs selected from a menu and guides a user to run them successfully according to the rules of analytical procedures. The database facilitates handling of both input and output data of application programs. The graphic human interface is the most important part of our system. Iconic and text menus, instead of a conventional command language, improve operational performance. Graphical presentations of analytical outputs, for example the color animation of power swings, aid understanding of power systems. The experimental results show that the new workstation highly contributes to effective power system analysis, although the computing speed is a little slow for large power systems.
