The invention provides a doubly-fed induction generator low-voltage ride-through control system which comprises a three-phase power gird, a doubly-fed motor, an inverter, a PLL (phase locked loop), a stator voltage and current Clarke conversion unit, a stator active power and reactive power calculation unit, a rotor current Clarke/Park conversion unit, a power outer ring, a rotor current inner ring, a SVPWM modulation and computing unit, and a Crowbar circuit. The low-voltage ride-through control system also comprises a stator damping resistor switching device, and the stator winding of the doubly-fed motor is connected to the three-phase power gird through the stator damping resistor switching device. The stator damping resistor switching device is realized by the parallel connection of a bidirectional thyristor and a damping resistor. The invention provides the doubly-fed induction generator low-voltage ride-through control system with the acceleration of stator magnetic linkage demagnetization process and the improvement of the control characteristic of a unit in a low voltage-ride through process.
