Abstract :
An application of the rule-based stabilizing control scheme to improve the overall stability of electric power systems is presented. Several simple rules are prepared for each generator in the system. The stabilizing signal for each generator is of the discrete type; it is renewed at every sampling time to control the generator excitation levels depending on the speed/acceleration state of the generator, using the measured speed deviation and the control rules. The efficiency of the proposed rule-based stabilizer is demonstrated by using a sample three-machine power system
