Design of a dual-excited synchronous machine and development of stabilization techniques

A dual-excited synchronous machine is designed and constructed. A power system is simulated using the machine and a medium length transmission line joined to the laboratory bus energized from B.C. Hydro which is considered the infinite bus. The effect of supplemental excitation control on power system stability is investigated. Feedback control is used in both the direct and quadrature fields. Torque angle, speed, power and terminal current signals are compared in their damping action. The response is also calculated from a ninth order mathematical model. It is found that the shaft speed is the best supplemental signal and that the direct and quadrature fields are equally effective in dynamically controlling the machine when operating near rated output.Applied Science, Faculty ofElectrical and Computer Engineering, Department ofGraduat
