摘要

In the case of power grid failure, the rotor side converter (RSC) of double fed wind generator (DFIG) will be shorted when Crowbar protection is activated, which results in the out of control of DFIG. And the traditional control method of converter can lead to the deterioration of control performance of DFIG. In view of the above problems, this paper improves converter control strategy on the basis of considering the dynamic changes of the stator excitation current and proposes fault ride-through scheme based on rotor series resistor. The proposed scheme is analyzed and its superiority is verified through Matlab/Simulink simulation platform. Simulation results show that the proposed method involving the cooperation between rotor series resistor and improved control strategy can help the DFIG achieve fault ride-through under grid faults condition, which is conducive to the stable operation of the wind power system.
