AB - This paper deals with control of wind turbine connected to the grid through  the back-to-back converter in case of unbalanced grid voltages. The  motivation for this research has been found in recent transmission and  distribution grid code, which demand modern wind turbines to stay connected  to the grid and supply the highest possible apparent power during the grid  disturbances. In order to comply with these requirements we proposed improved  dual vector current controller to deal with the unbalance imposed by the  electrical grid. Controller provides injection of active and reactive power  to the grid, even if the voltages are lower than the nominal one. The results  are validated using low power prototype and contemporary hardware-in-the-loop  emulation platform. In both cases the controller is based on TMS320F2812 DSP.
