AN ABSTRACT OF THE THESIS OF Shibashis Bhowmik for the degree
Dynamic control of brushless doubly-fed machines

Creator:

Zhou, Dongsheng, 1964-

Abstract:

This thesis presents the development of dynamic control strategies for the brushless doubly-fed machine (BDFM). A simple open-loop scalar controller is first investigated and its response is found to be oscillatory. Using the speed feedback signal, an improved closed loop scalar control algorithm is designed. Steady state performance is controlled...

Voltage sag and momentary interruption ride-through for adjustable speed drives

Creator:

van Zyl, Annabelle

Abstract:

The awareness of electric power quality has increased over the past decade as electronic equipment has become more susceptible to power disturbances. The most disruptive power disturbances are voltage sags and momentary interruptions and their effect on adjustable speed drives (ASDs) is studied in this thesis. Several solutions have been...
