Abstract
Transient stability of an alternator under fault condition and after removal of the fault has been studied in great details by many authors. The stability studies have been made either on grid systems or on one machine on infinite bus idealization. The saliency effect, saturation and damping (due to both damper winding and solid iron rotor) have been accounted for by many authors. But in many cases, the effect of fast-acting control systems like automatic voltage regulator and exciter has not been considered. Transients caused by the turbine governor are slow and may be neglected, but not the fast-acting exciter control. This paper is devoted to assessment of stability in the presence of AVR exciter. A suitable model of IEEE has been chosen for the specific case study, which has been subsequently mapped to state space. The composite model has been developed from which both transient stability and dynamic stability have been assessed. The boiler and firing control is extremely sluggish—hence their effect has been neglected.
