In this study, the effect of parametric variation of pole arc offset distance on the performance of a Permanent-Magnet Synchronous Generator (PMSG) used in wind energy applications has been investigated. Fourier analyses of the voltage wave-shapes that are obtained by the parametric variation of the pole arc offset value have been made. The THD is determined for each voltage wave-shape. As a result of optimization study, the efficiency and output power have been kept approximately constant. The THD of the output voltage has decreased. (c) 2017 Sharif University of Technology.
