An object based graphical user interface for power systems

Object-based graphical user interfaces (GUIs) that may be used as flexible, device independent front-ends for power system simulation and control are discussed. An experimental prototype GUI suitable for energy management systems or operator training simulators is described. The GUI is based on the X window environment and uses multiple windows to display differing views of the system and direct mouse manipulations to affect the various power system objects in a consistent fashion. An editing portion of the system allows the dynamic construction of one-line diagrams, although an advanced automatic display generation feature capable of constructing layouts based on database information and sophisticated routing and layout heuristics is also provided. The X window (and C) basis of the implementation of the system provides for its relative platform and operating system independence, and allows the networked operation of multiple platforms running the same functions. The aim of this study is to document the generic features and advantages of such a GUI
