Investigation of the power quality of wind permanent magnet synchronous generator

During the last few years more and more permanent magnet synchronous generator are being introduced thanks to the use of direct drive train and lack of excitation. This whole generated energy is converted by a power electronic converter, based on pulse width modulation. The switching frequency shifts the injected harmonics to grid. In this paper the power quality both measured in a wind park and by using mathematical modeling, is being researched. The results are shown and a comparison which shows a lot of matches of the outcome characteristics is made.
