System Transient Stability Due to Various Contingency Using Power World Simulator

A change in load, switching operation, abrupt faults, and loss excitation are the causes of the transient disturbance. Therefore, it is crucial to regain synchronism or equilibrium upon disruptions to the electrical services. This paper focused on the analysis of transient stability of IEEE 9-bus system using Power World Simulator. The Newton-Raphson approach will be used during the load flow studies to determine the pre-fault conditions in the system. The system's variation in rotor angle, frequency, and voltage will then be investigated with the use of a three-phase balanced fault. It is concluded for different contingency test, there will be rotor deviation, changes in frequency and changes in voltage in per unit. Additionally, the critical clearing time of the system will vary depending on the contingencies test. Investigating the stability of the power system during abrupt and large disturbances is done using transient stability analysis, which is crucial to preserving the safety of power system operation.
