Performance Evaluation of the IEEE 9-Bus Power System Under Various Fault Conditions using a Simulation based Approach

This research paper offers a simulation based comparative study of fault conditions in a typical IEEE 9-bus power system to assess system performance and stability under different disturbance conditions. The analysis is concerned with typical fault types which are essential in the analysis of power system operating flexibility. It is inserted that 100% fault location take place between bus 4 and bus 5. The 9-bus network model is simulated using power world simulator with every fault type, and voltage magnitude, current, and phase angle are closely monitored. The simulation results reveal information regarding how fault severity variations affect system operation. Comparative studies show that three-phase faults cause the deepest voltage dips due to current value 3765 A. The significance of faults result gives the proper fault detection, identification, and protection coordination to improve system reliability. The study is a valuable contribution toward improved fault management practices, which are imperative to ensure the stability and integrity of modern power systems with many interconnections system.
