High speed induction generators

Full converter ( FC ) concept using standard high speed drivetrain can also be realized with asynchronous squirrel cage induction generators (SQIG) instead of the high efficiency HS PMGs. SQIGs offer robust conventional technology with good efficiency and small size.

Unlike Doubly-fed, in FC concept all the generated power goes through a “full size“converter. It offers full variable speed operation and advanced grid code compliance also in the future, fully separating the mechanical drivetrain from the grid disturbances.

 ABB is the leader in converter duty applications for over 30 years, when ABB introduced the first converters to the world markets. Using converters imposes many technical challenges concerning the electrical dimensioning and insulation of reliable generators that match perfectly with the drive.

 In addition to other industries using variable speed motors, ABB has delivered nearly 10 000 SQIGs for FC application to leading wind turbine manufacturers since 2003.
