Graphical user interface for next generation power systems

The world of telecommunications is a world of transmission of information. However microprocessor based controllers used in power systems typically offer broad information. Typical menus in today's user interface are text based with difficult navigation. The operators must be specialized in power and be specifically trained to operate the equipment and to be able to decode the various messages and outputs from user interfaces. To make this mass of information more accessible and easier to use, the human-machine interface must be designed in a methodical way, from the hardware support to the information provided to the user. The choice of technology is very important, as well as presentation of the data. The technology determines the possibilities and the limitations for the design. Using that technology, the data must be grouped and organized in an intuitive way to allow any user, specialist or unskilled person to navigate easily in the environment and to find the information required. The paper describes a recommended design process and approach to develop a user friendly graphical user interface (GUI). This process has a very methodical approach backed by academic concepts. The goal is to facilitate the use and comprehension of power equipment by developing a simple tool that is very intuitive and easy to use. An example of a human-machine interface on a PC based power system controller is demonstrated.
