Abstract :
A new methodology is proposed in this paper, it is based on Adomian-Pade method and it is used to characterize power system Oscillations. The differential equations of the system are solved using Adomian method and the oscillation characteristics are obtained by applying Pade approximation on this solution. The developed methodology is applied on a single machine - infinite bus system to identify oscillation modes. Results are compared against those obtained by commercial transient stability software.
