This paper presents a new control structure for the synchronous generator excitation control in its capacitive operating area. The proposed method enables the generator to operate stably close to the stability limit, extending its capacitive operating area. As to generator stability, the main variable is the generator load angle, hence the proposed method suggests using a load angle controller along with a voltage controller. The proposed algorithm has been implemented in a digital system based on a signal processor and has been experimentally verified on a lab model.
