ABSTRACT: 
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.

CONCLUSION: 
Through apply the phasor solution method to modeling and simulation for the transient stability 
analysis of a simple transmission system containing two hydraulic power plants, shows that the 
phasor solution method can reduce the system simulation time greatly and has good precision. 
This solution method still can be applied to simulate more complex power grids.
