Abstract or Summary
  • This thesis presents the development of a supervisory controller for a pre-commercial Brushless Doubly-Fed Machine (BDFM) drive system. In addition, characterizations of new diecast rotors for the BDFM are presented. Using the characterization results from the new rotors, a control scheme was developed to allow a BDFM to be packaged into an integrated drive system, which is specific to the doubly-fed nature of this machine. Experimental evaluation of the diecast rotors indicates that this form of rotor production can be applied to BDFMs and allows for mass production at reasonable cost. The control system was integrated within the BDFM drive system, making the first self-contained BDFM drive a reality. Since this drive is intended to be a prototype for commercial development, this thesis contains a detailed account of the supervisory control, how it was implemented, and how it can be operated or reconfigured. This controller has a number of functions, including: host for the user interface, synchronization control, speed control, ensuring optimum performance, and establishing active power factor correction.
