Abstract: The inter-area oscillations are highly non-linear and complex in nature. They are not easily damped by the conventional Power System Stabilizers. They cause the interruptions in the flow of bulk power in between two areas and sometimes they may cause the breaking of power system, if not damped sufficiently. Inter-Area oscillations contribute significant importance because they involve various units belonging to different areas in power system. They may cause greater oscillations in the tie line connecting various units. To analyse these inter-area oscillations, the entire power system has to be represented in detail. The analysis has also be done on how the certain quantity of power is transferred from one area to another which are interconnected by tie- line.
