A DFIG Wind-Turbine Ride-Through System Influence on the Energy Production
Paper in proceedings, 2004

The influence on the energy production of a voltage sag ride-through systems, for a doubly-fed induction generator (DFIG) wind turbine, is investigated. Based on simulations a candidate ride-through system, based on IGBT modules with high current rating and anti-parallel thyristors that can disconnect the stator of the DFIG from the grid, is developed. It has been found that by increasing the current rating, of the converters IGBTs, the losses of the converter can be reduced. However, if anti-parallel thyristors has to be connected between the stator and the grid, in order to achieve a fast disconnection, the over all losses of the total system increase instead.
