The terminal-connected series dynamic braking resistor (SDBR) is applied to assist the low-voltage ride-through (LVRT) of the doubly-fed induction generator (DFIG). With the fault current and switch-in of the SDBR. the stator voltage oscillates. thus the constant stator voltage drop assumption is invalid and the effect of the converter current control is weakened with the changing vol... https://www.markbroyard.com/
