Transient Stability Analysis and Simulation of a Five-Buses Electric Power System During a Three-Phase Fault Event

Electric transient stability is recognized as one of the most prevalent issues affecting electric power systems. To ensure a secure electric power system, it is essential to examine all facets of system stability. Various aspects of power system stability have been utilized to assess oscillations and interruptions within the electric power system under different scenarios, which may arise from various types of faults. This paper presents a simulation of a five-busbar electric power system using the Electrical Transient and Analysis Program (ETAP). The analysis includes the waveforms of currents, voltages, and frequencies for each component of the power system. When a three-phase fault occurs at any location within the electric power system, oscillations are induced by the fault, leading to instability. If the fault is rectified within a specified timeframe, the power system is likely to regain stability; otherwise, it will continue to operate in an unstable manner.
