Delayed Feedback Control of Three Synchronous Generators Infinite-bus System

Abstract

Delayed Feedback method for controlling three machines operating onto an infinite-bus system is investigated by computer simulation. Only internal state is necessary for this method. The time series of phase angle of generators with an accident of transmission lines shows the irregular motion and the step-out. It is shown that the irregular motion of the electric power system is controlled onto the stable equilibrium points with the six stable manifolds by delayed feedback control.
