Improved DC-Link Voltage Control for Double-Fed Induction Generator during Grid Fault

Abstract:

Transient capability improvement of doubly fed induction generator (DFIG) during low voltage ride-through (LVRT) is important for both generator and grid safety. A theoretical current control method is introduced here to deal with LVRT of wind turbines with DFIG under symmetrical voltage dips. The objective is achieved by balancing the energy that flows in and out the DC-link capacitor. Simulations performed by Matlab software demonstrate the capabilities of the proposed method in enhancing the DFIG’s performance during low voltage ride-through.
