Application of Concentrated Windings for High-Power Synchronous Wind Generators

Abstract

The article analyzes the parameters of various configurations concentrated windings for application in high-power geared and direct drive wind generators. It is specified that the concentrated windings advantages over distributed ones can be fully realized by choosing the right values of pole pairs and the slots number. It is shown that the choice of the winding should take into account not only the highest winding factor, but also to the star of slots for the analysis of the harmonic contents of the magnetomotive force (MMF) and electromotive force (EMF), cogging torque and load torque pulsation. Windings with performance conditions Z=12+6k, 2p=Z ±2, k=0,1,2,3,…having an odd number of pole pairs are recommended for high-power wind generators.
