The state of wind turbine technology is defined by comparison of each type. Squirrel Cage Induction
generators (SCIG) has the two modes of induction generators normally used for geared operation in fixed speeds and
variable speeds, doubly fed induction generators (DFIG), and wound rotor induction generator (WRIG) while the
types of synchronous generator defined by Wound rotor synchronous generator (WRSG) and Permanent Magnet
Synchronous generators (PMSG) can operate gearless. These all types of induction and synchronous generator
defined with advantages and disadvantages. Cause of higher demand of power from wind energy system, off shore
installations is becoming more popular.
