Power Converter Interfaces for Wind Energy Systems - A Review

The paper attempts to bring out a wide-ranging analysis the performance of electronic converter interfaces that assuage to meritoriously control a Wind Energy Conversion System (WECS). The system seems to gather significance in an effort to exploit the natural resources and offer support to associate the generation demand gap. The effective practice of the wind power augurs to carry down the cost of generation and encourage to satisfy the needs of the utilities. The WECS exist in the form of the variable speed generators and the types include the Permanent Magnet Synchronous Generator (PMSG), Doubly-fed Induction Generator (DFIG), Synchronous Generator (SG) and Wound Rotor Induction Generator (WRIG). The DFIG invites a greater attention owing to its smaller requirement of the partially rated converters and enables to regulate the system through a compliance for the transfer the real and reactive power.
