The transient voltage stability analysis method based on Monte Carlo method and frequency domain analysis is studied.The IEEE 39-node standard system is modeled by simulation,and the 16#node is set with three short-circuit faults lasting 0.1 s,which verifies the effectiveness of the proposed method.The experimental results show that this method can accurately capture the voltage fluctuation range of the system after the fault,show high analysis accuracy and stability,and provide a scientific evaluation method for the transient voltage stability of large-scale power systems.
