Abstract

This research develops a low speed wind system based on an axial flux permanent magnet generator with distributed winding and circular magnet shape and a modular multilevel inverter. Machine is modeled by 3D finite element method to obtain the characteristics of the machine and calculate the maximum value of the flux density, which is necessary to simulate the dynamic model of the wind system. Detailed model of the inverter and a control method for protecting the voltage balance are described. Finally the performance of the wind system is evaluated by simulating whole model of the system.
