  Transient stability analysis (TSA) plays an important role in power system
analysis to investigate the stability of power system. Traditionally, transient
stability analysis methods have been developed using time domain simulation by
means of numerical integration method. In this paper, a new approach is
proposed to model power systems as an integrated circuit and simulate the power
system dynamic behavior by integrated circuit simulator. The proposed method
modeled power grid, generator, governor, and exciter with high fidelity. The
power system dynamic simulation accuracy and efficiency of the proposed
approach are verified and demonstrated by case study on an IEEE standard
system.
