Abstract

Chaotic phenomena in dynamic systems represents on urgent task. It is particularly important in control of technical systems. The work deals with Hopf bifurcation and chaos in power systems. A three-machine system which is close to real systems is considered. Conditions are revealed in which bifurcation and chaos take place in power systems. For a three-generator system the torus is built in the phase space which corresponds to Arnold diffusion. A characteristic equation is given which describes a three-machine system and the analysis of the characteristic equation makes it possible to analyse Hopf bifurcation and random motions in power systems
