Effect of Low Voltage Ride Through Technologies on Wind Farm

Doubly fed induction generators (DFIG) offer many advantage when used with wind turbines. Given their configuration, they are particularly sensitive to grid faults. As many countries now require wind turbine generators to remain connected to the grid during faults, low voltage ride through solutions are being developed to fulfill this new requirement. This paper offers a comparison of different LVRT solutions. The effects of each method on a small network containing both conventional generators and wind turbines are investigated. The performance of the different solutions is evaluated based on the wind turbines response.
