Modeling and Simulating for Transient Stability Analysis of Power System Using Dynamic Phasor

In this paper, using a new solution method, the phasor simulation, a model of two-machine power system with static var compensators (SVC) and power system stabilizers (PSS) is built. By this system model, the transient stability analysis of this two-machine power system when single-phase fault and 3-phase fault is simulated. The result shows that the phasor solution method can reduce simulation time greatly of power grids, and has good precision.
