| | Transformer Based Voltage Sag Generator to test Renewable Energy Systems during Grid Faults in the Laboratory (Paper)
By C. Wessels; T. Wehrend; F. W. Fuchs | |
|
Abstract: A transformer based voltage sag generator to test renewable energy systems is presented. Design
considerations concerning overvoltages and overcurrents during switching action are adressed. Measurement results of a 30 kW laboratory prototype testing a line side PWM converter and a DFIG are
presented. Both measurement results for investigations on the transformer based sag generator at the line side converter and the DFIG show the superb fuctionality of the sag generator. Voltage dips of variable depth, duration time and fault type can be generated without overvoltages or voltage interruptions.

| | The importance of considering DFIG‘s fault ride-through capability during asymmetric faults (Paper)
By M. Itsaso Martinez; Ana Susperregui; Gerardo Tapia; Haritza Camblong | |

Abstract: DFIGs’ ability to generate power decreases considerably during faults. Nevertheless, it is still not clear
how such a reduction is developed. Consequently, the system may be over demanded, ending up tripping the wind turbine. Thereby, this paper presents an analysis of DFIGs’ capability to generate
power and ride-through asymmetric faults.
