Ingeteam improves DFIG’s fault ride through behavior with crowbarless solution

By Paul Dvorak Ingeteam has announced the introduction of its Crowbarless solution, a modular Fault Ride Through (FRT) system for power converters that will strengthen the grid compliance of doubly-fed induction generators (DFIG). Thanks to the modular FRT system, the Crowbarless solution offers superior capabilities compared to the active crowbar system traditionally used to protect the power converter from grid voltage transient.
The Crowbarless design presents behavioral advantages in issues related to weak grids or grid fault events, letting doubly fed induction generators overcome previous technical constraints and hence comply with the strictest grid codes.
Until recently, most grid codes let wind turbines disconnect from
