چکیده:

This paper presents a new method for designing nonlinear power svstem stabilizer to improve transient and dynamic stability. In these studies, a 4th order nonlinear model of synchronous generator has been used. First the existence of a diffeomorphism Transformation for nonlinear power system has been proved and then, the nonlinear model has been transformed to a canonical form using inputoutput linearization method. Finally’. the linearized model is controlled using sliding mode technique. At these procedures. The stability of zero dynamics has been attained. The simulation results on a single machine connected to ail infinite bits. show the good performance of the stabilizer.
