摘要
This paper presents an optimal design approach for a double-stator permanent magnet brushless synchronous wind generator that is used in direct drive wind turbine applications. Poles and slots number of generator were so chosen that the torque ripple and Total Harmonic Distortion (THD) of voltage were reduced. Winding design method and number of slots to number of poles ratio were selected in such a way that maximum winding factor to be achieved. Simulation results showed that lower THD of voltage and torque ripple were obtained by using Finite Element Method (FEM) and technical selection of parameters. The proportions of pole arc to pole pitch and slot opening to slot width of this generator were obtained for minimum torque ripple and voltage THD. Also, after optimization by genetic algorithm, power density and efficiency of the generator were effectively enhanced.
