This paper presents a generalized method to analyze auto-parametric resonance which would be regarded as a kind of nonlinear oscillation in power systems. In the present work, the equation is generalized to analyze a resonance among multiple modes by using the Method of Multiple Scales, an excellent method for analyzing large scale nonlinear systems. It is demonstrated through numerical simulations that the generalized envelope equation is valid for predicting the resonance phenomena themselves and also for examining critical factors of how severe resonances are aroused. The factors chosen for study here are: the degree of heavy loads, small dampings and large disturbances. The method is promising with regard to the analysis of various facets of general multi-mode resonances.
