Abstract: This thesis deals with the investigation of stability problems that limit the MW transfer capability of longitudinally interconnected power system. The focus of the investigation is on the effects of excitation system and power system stabilizer on enhancing the system stability. The extra emphasis is on the preliminary design of power system stabilizer for the single machine connected to infinite bus power system, using the frequency-domain approach. The systema??s responses to small and large perturbations are examined, utilizing the time-domain simulation. Dynamic voltage stability is investigated by means of Hopf bifurcations, using the eigen-values analysis. Static operating limits of round-rotor generator are modeled. Simulation studies are carried out to investigate all the aforementioned limits and their effects on the MW transfer capability of the system. To provide a sound control over the system interconnection, the load-frequency control of the hydro-power generation in the study system is also examined.
