Abstract
  • The brushless doubly fed machine (BDFM), or self-cascade single-frame machine, can operate asynchronously or synchronously over a wide speed range. In this sense the machine becomes an adjustable speed synchronous machine. Such machines may become unstable in certain regions of operation. Analyzing its steady-state performance and determining its stable operating regions are very important efforts to pursue. This thesis presents the theory and its verification in order to predict the steady-state operating performance of the BDFM using a method based on circle diagrams. The stable regions and the loci of operating points for different mechanical input characteristics are presented.
