Abstract
In the case of power grid failure, the rotor side converter of double fed wind generator will be shorted when Crowbar protection circuit is put into, which results in the out of control of doubly fed wind power generator.Then the traditional control method of converter will lead to the deterioration of control performance of doubly fed wind generator.As to above problems, this paper improves converter control strategy by considering the dynamic changes of the stator excitation current, and proposes fault ride-through scheme by combining with rotor series resistor.The proposed scheme is analyzed and its superiority is verified through Matlab/Simulink software.Simulation results show that the improved control strategy coordinating with rotor series resistor method can help doubly fed generator ride through the serious fault of the power grid, which is conducive to the operation stability of the wind power system.关键词
