Abstract
The interaction between rotor-side and grid-side converters (RS-GSCs) has a significant impact on the low-voltage ride-through (LVRT) performance of grid-connected wind turbine based on doubly fed induction generator (WT-DFIG) during severe symmetrical grid faults. Hence, to improve the LVRT performance of the WT-DFIG during symmetrical grid faults, this letter proposed an LVRT control strategy, which is implemented by coordinating the current references of RS-GSCs. Compared to existing LVRT strategies, by coordinating the active and reactive currents of the RS-GSCs, the proposed strategy could enhance not only the transient stability level of DC-link voltage, but also the LVRT performance of the WT-DFIG. Finally, the validation was carried out using an experimental system.
