Comparison of DDPMSG and DFIG concepts for wind turbines

Through this paper, following the classification of wind turbines in four main topologies based on their generators, different aspects of the two dominant and state of the art concepts of wind turbine (WT) configurations, the direct drive permanent magnet synchronous generator (DDPMSG) type and doubly fed induction generator (DFIG) type, will be assessed. Among this investigation, it is aimed to compare different aspects of basic electrical components such as the generators, converters and controlling methods of these two WT´s structure to introduce the superior one. This comparison will include some dominant contracture of generators as well as different exerted converters and applied drives.
