Transient Stability Analysis of Power Systems using Mi Power

This paper investigates the transient stability analysis of power systems utilizing MI Power, with a focus on the dynamic behaviour of generator angles, bus voltages, and system frequency during fault scenarios. Transient stability is a vital component of power system functionality, ensuring the system can revert to stable operation following disturbances. The study employs MI Power’s load flow analysis capabilities, specifically the Newton-Raphson method, to ascertain pre-fault conditions, including voltage magnitudes, angles, and power flows at each bus. The analysis commences with a comprehensive evaluation of the system under standard operating conditions to establish reference parameters. Subsequently, fault conditions are simulated to examine their impact on generator rotor angles, bus voltage profiles, and frequency fluctuations. Significant findings include the degree of angular displacement in generators, voltage reductions across buses, and frequency variations resulting from disturbances. The system’s capacity to recover from these changes is assessed, providing valuable insights into its transient response characteristics. The findings reveal that the stability of the system is heavily influenced by the dynamics of the generator’s rotor angles, voltage recovery processes, and frequency stabilization. This study enhances the understanding of these factors, aiding in the development of power systems that exhibit greater stability and resilience in the face of faults.
