Design of a controller for reduced order model of an SMIB power system using pole placement technique

Abstract

In order to design a large interconnected  system and to gurantee  the system  stability at a minimum cost it is very complex.From control theory point of view, power system is a higher order multivariable process which operates constantly in a changing environment. Hence, it is necessary to perfom the order reduction, for such a complex system. In this paper order reduction techniques i.e. Modal Analysis Approach methods have been used to reduce the stable higher order system to a stable lower order model.
