Abstract
In this paper, a modified direct feedback linearization method for transient stability and voltage regulation of power systems is discussed. Starting with the classical direct feedback linearization technique currently applied to power systems, a modification is proposed in the equation of excitation control of synchronous generators in order to eliminate the static error of the terminal generator voltage. This modification takes into account the change of the reactance line after a three-phase short circuit. The proposed method is based on a standard third-order model of a synchronous generator which requires only information about the physical available measurements of angular speed, active electric power and generator terminal voltage. Simulation results show that this technique presents a fast response and a robustness compared with the Power System Stabilizer (PSS) and the Direct Feedback Linearization (DFL). They also demonstrate that the damping, the steady-state and the transient stability as well as voltage regulation are all achieved satisfactorily.
