Wind Energy Systems 2

The power extracted from the wind is given by the relation

Which generator is preferred in wind energy extraction

• Squirrel cage induction generator

• Permanent magnet synchronous generator

• Doubly-fed induction generator

• Wound round induction generator

Soft starters is used in SCIG based Wind Energy system to limit

• Speed

• Frequency

• Vibration

• Inrush current

Doubly fed Induction generator named because

• Two generators connected in series

• Two generators connected in parallel

• Both stator and rotor fed power to the grid

• Two generators connected in capacitor

The induction generator commonly used in direct drive application is

• SCIG

• WRIG

• DFIG

• PMSG
