Study of Power Converters for DFIG Based Wind Energy Conversion Systems

R. Venkatasubramanian, Dr. T.A. Raghavendiran

Abstract


This paper explains a different converter topologies with different induction generators used for wind energy conversion system. In this focussed area of renewable energy resources, wind energy conversion system is more popular than the other conversion systems. Four main types of induction generator used in wind energy conversion system (WECS) are Squirrel Cage Induction Generator (SCIG), Permanent Magnet Synchronous Generator (PMSG), Doubly Fed Induction Generator (DFIG), and Wound Field Synchronous Generator (WFSG). Presently, doubly-fed induction generator (DFIG) is widely employed in modern wind power industries. The maximum electrical power can be obtained in both wind speeds of above and below synchronous speed using DFIG. Also, it reduces the power rating of the converter. This paper mainly explains the study concepts of Power converter topologies in used with Doubly Fed Induction Generator (DFIG) connected wind energy conversion system.
