PROJECT TITLE :

Analytical Calculation of Synchronous Reactances of Homopolar Inductor Alternator

ABSTRACT:

During this paper, the direct-axis ( -axis) and quadrature-axis ( -axis) synchronous reactances of homopolar inductor alternator (HIA) are calculated. First, an approximate a pair of-D model of HIA is developed and its relative air-gap permeance function is described. Then, the analytical expressions for the synchronous reactances within the -axis and -axis are derived from magnetomotive force-relative air-gap permeance function theory, including armature reaction reactance and armature leakage reactance. Finally, theoretical results are compared with the simulation and experimental results.
