AN OBJECT BASED GRAPHICAL USER INTERFACE FOR POWER-SYSTEMS

This paper discusses object-based graphical user interfaces that may b e used as a flexible, device independent front-end for power system si mulation and control. This discussion is illustrated by an experimenta l prototype GUI suitable for energy management systems or operator tra ining simulators. The GUI is based on the X window environment and emp loys multiple windows to display differing views of the system and dir ect mouse-manipulations to affect the various power system objects in a consistent fashion, ensuring ease of use. An editing portion of the system allows the dynamic construction of one-line diagrams in a paint -program-like environment, although an advanced automatic display gene ration feature is also provided which is capable of constructing layou ts based on database information and sophisticated routing and layout heuristics. The X window (and 'C') basis of the implementation of the system provides for its relative platform and operating system indepen dence, and additionally enables the networked operation of multiple pl atforms running the same functions. As the industry is already moving in these directions, the aim of this paper is to document the generic features and advantages of such a GUI.
