Abstract
This paper describes a method of stabilizing control for a dual-excited synchronous generator connected to an infinite-bus system. The method is based on a combination control scheme in which is used a phase control of resultant flux-linkage produced by d-and q-axis field windings jointly with the feedback controls of generator terminal voltage and electrical output. The proposed controls consisting of two excitation systems are implemented on a laboratory size 3kVA generator with a personal computer acting as the digital controller. The experimental results show that the synthesized control method is suitable for improving the transient stability subjected to large disturbances in a dual-excited synchronous generator infinite-bus system.
