| Abstract: | First of all, some basic concepts of perturbation method are introduced. And then,three main singular perturbation methods are elaborated. Lastly, some applications of the method of matched asymptotic expansions, the method of KB average, and the generalized KB method and the modified KBM method proposed by Dai Shiqiang in nonlinear control,analysis of nonlinear resonance, and the investigation of strongly nonlinear oscillations in electrical engineering of modem power systems are presented. In this way, the great application potentiality of perturbation method in power systems is showed. |
