Torque control of a wind turbine using 6-phase synchronous generator and a dc/dc converter

Abstract

In this thesis an electrical system for a torque controlled synchronous generator for wind power applications is developed. The setup is made simple with a diode rectifier and a boost converter where the boost converter provided the torque control. Two different generators are tested, an EMSG, Electrically magnetized synchronous generator, and a BLDC generator, Brushless direct current. A comparison is made between them to investigate the best working machine. The conclusion in this thesis is that the electrical system works well for both generators in low wind speeds an that the EMSG provides the best results because it is shown that it was easier to filter out the harmonics when this generator was used.
