COMPARATIVE STUDY OF DOUBLY FED INDUCTION GENERATOR AND PERMANENT MAGNET SYNCHRONOUS GENERATOR IN WIND ENERGY CONVERSION SYSTEM

The objective of this research paper is to compare various types of generator used in Wind Energy Conversion system topologies. Now a days there is fast growth of variable speed WECS due to rapid advances in power electronics technologies. In present scenario there are primarily two types of generators used in WECS namely Doubly Fed Induction Generator(DFIG) used for geared operation for variable speeds and fixed speeds and Permanent Magnet Synchronous generator(PMSG) can operate gearless. As there is higher demand of power, offshore installations are gaining popularity and hence new wind turbine designs are being expected in near future, as there will be development in generators and converter design.
