Abstract

PEREZ LONDONO, Sandra Milena; OLIVAR TOST, Gerard  and  ANGULO GARCIA, Fabiola. Bifurcation Analysis: Comparative study over a single machine - infinite bus system. Rev.fac.ing.univ. Antioquia [online]. 2011, n.59, pp.108-121. ISSN 0120-6230.

In this paper, the dynamics of a straightforward system which includes a single machine-infinite bus power system (SMIB) with soft-limits in the field excitation control is presented. The system is forced to operate under several conditions for studying its behavior close to codimension-two bifurcation points. We specifically consider the Zero-Hopf bifurcation, which contributes significantly to the system dynamics.

Keywords : Bifurcations; power system dynamics; stability; soft limiter.
