| Determination of stability characteristics of a power system is considered as a substantial issue with the increasing complexity of power systems. Power system stability is defined as the behavior of the electrical power system under sudden or sequence of disturbances when it is operating in steady state. It could be a problem of voltage stability, frequency stability or rotor angle stability depending of the type of disturbance. Transient stability which is a sub section of rotor angle stability, is concerned with the condition in which the synchronous machines in the system remain in synchronism or 'in-step' with each other when the system is subjected to severe disturbances. In multi-machine power system, transient stability analysis is an indispensable tool in the areas of planning, design, operation and research.; The nonlinear nature under disturbance is not linearised for the purpose of analyzing transient stability. Therefore, the theories and methodologies for transient stability analysis based on approximations and assumptions. This study is to prepare an educational software package to understand the transient stability behavior while understanding the theories and methodologies behind it.
