Abstract Doubly-fed induction generators (DFIGs) have been widely used in wind generation because of their less loss and simple control strategy. There are many ways to reduce the current and voltage fluctuation in fault duration in DFIG and crowbar circuit is a widely used method. However, the crowbar circuit cannot limit the current and voltage after fault very effectively. This paper analyses the model of DFIG and proposes a method to evaluate the dynamic response of DFIG after fault. The new crowbar circuit with capacitance in series with a resistance is used in the model and three ways to calculate the optimized capacitance are proposed in the paper. Finally, MATLAB/SIMULINK is used to build a wind farm model to verify the effectiveness of the theoretical investigation.
