Fault Analysis Toolbox using Matlab with Graphical User Interface (GUI)

The Fault Analysis Toolbox for MATLAB with Graphical User Interface is presented in this paper (GUI). In MATLAB, a graphical user interface (GUI) is a tool that automatically visualizes and analyses data using programming. The different types of faults that commonly occur in power system analysis were calculated using this GUI tool. During the occurrence of fault, the bus voltages and fault currents were observed. Fault analysis can be categorized into balanced and unbalanced three-phase faults. In this paper, a 3-bus, 11-bus and 30-bus system were used since the aim was to develop a GUI tool focused for education purposes. It was focused on instances of faults that occur in the theoretical field. Since MATLAB is so well-known among engineering students, another goal is to build a user-friendly visual tool. As a result, fault analysis can be easily understood and analysed by the individual who requires a user-friendly visual tool.
