LVRT-DGFACTS devices in wind farms

This article compares the results recorded in the connection of three types of DGFACTS (DSTATCOM, DVR, UPQC) to a wind farm in order to resolve the issues of LVRT requirements on wind farms equipped with wind turbines with squirrel-cage induction generators. For illustrative purposes, reference has been made to a standard wind farm in Spain, which has been subject to a fault of the type specified in Operating Procedure 12.3 in the Spanish Grid Code. The aforementioned options provide the wind farms with LVRT capability, in addition to catering for numerous other possibilities that have not been considered within this research.
