Abstract	:	One of the most important and complex tasks in power engineering is the analysis of power systems under fault conditions. The detection and analysis of these faults are important to guarantee that the dependability and stability of the power system does not decline as a result of a critical event such as a fault. This thesis will conduct research on how a power system under fault conditions behaves and will examine the various scenarios of faults such as three-phase, single line-to-ground, line-to-line, and double line-to-ground faults. A simplified method based on symmetrical components is used to construct the mathematical models that calculate the fault currents and the fault voltages. A MATLAB/ Graphical User Interface based simulation tool has been developed to use as an educational tool and these models have been integrated into a MATLAB/ Graphical User Interface. This GUI has an option to enter input data and select the fault type and will provide the calculation of three-phase, single line-to-ground, line-to-line, and double line-to-ground faults on power systems. These calculated fault currents and voltages display on a GUI screen along with the time variations of signal. A so called "Educational resources zone" was also added with various text from literature and videos on power system analysis so that the students can have a better understanding. In this way, the developed MATLAB GUI simulation tool can be used by students to check the accuracy of the hand calculations and to observe the transient wave forms of fault current and voltages.
