Abstract: Inter-area oscillation will seriously affect the normal operation of the system. Once the line cascading failure occurs, the system will produce greater disturbance. The inter-area oscillations occurring in the Eastern Interconnection of United States were investigated by six typical cases using the frequency monitoring network (FNET) data. The matrix pencil method of multiple signals was used for the modal analysis. The parameters related to mode shape were calculated. The mode shapes for the dominant mode are revealed for each case. Analysis results depict a view of inter-area mode distribution in the Eastern Interconnection.
            Key words: inter-area oscillation; matrix pencil; mode shape; wide area monitoring system
