Abstract
A physically realizable linear optimal controller in terms of easily measurable state variables for the stabilization of power system is developed in this paper. The controller is based on a fairly accurate fifth order synchronous machine and a first order voltage regulator. The transformation of the system equations into a cannonical form enables us to determine the weighting matrices Q and R of the quadratic cost function with simple procedure and to design an optimal controller which can stabilize a power system under widel. power range operating conditions. Transient response test on the nonlinear model proves the effectiveness of the linear control design.Keywords
