Abstract

This paper describes the dynamic model of a gas turbine generator, which supplies a radial
distribution system. An optimal controller for the excitation system is designed based on the
linear model. The response of the closed loop system with optimal and conventional
controllers are compared under different type of electrical disturbances such as a 3-phase short
circuit at different loads and switching some of loads off or on.
