摘要：

Based on the characteristics that DVR(Dynamic Voltage Restorer) can restore voltage in a short time, the capability of DVR to assist DFIG(Doubly-Fed Induction Generator) wind turbines for the improvement of asymmetrical voltage fault ride-through is investigated. For DFIG wind turbines, the topology and compensation strategy of DVR are selected. The DVR control method based on proportional-resonant controller is analyzed and a single-loop voltage feedback control strategy is proposed. The simulation experiments are performed with PSCAD/EMTDC. Results show that DFIG wind turbines can successfully ride through asymmetrical voltage faults under DVR protection and its improved transient behaviors. © 2019, Electric Power Automation Equipment Press.
