This paper deals with the analysis of the inter-area mode phenomenon in stressed power systems following large disturbances. It is shown that the inter-area mode phenomenon could occur as a result of a nonlinear interaction of the natural modes of oscillation in the system. A technique to determine the interaction is developed and the machines participating in the interaction are identified. A procedure to predict the onset of the inter-area mode is presented. The analysis and the procedure developed are tested on two systems: a 50-generator system and a 126-generator system.
