Windows based graphical tool for symmetrical components analysis

A new windows based graphical tool to facilitate the teaching and learning the symmetrical components analysis is described In this paper. This software provides a user-friendly environment to aid the studies of symmetrical components. The software calculates and displays graphically the ABC sequence and the corresponding phasors of symmetrical components. Taking the advantages of the graphical user interface (GUI), it provides the student with interactive visual communication to analyze and better understand the relationship between the ABC sequence and symmetrical components. Students can manipulate the graphical displays either using keyboard input or mouse operation. Besides, students can use this tool to analyze the unsymmetrical short circuit fault currents. It is hoped that this tool makes the learning process more interactive, interesting and user friendly.
