摘要：In recent decades, the installed capacity of wind power is increased greatly, and doubly fed induction generator (DFIG) occupies a dominant position among wind power generators due to its excellent characteristics. However, how to improve the low voltage ride through (LVRT) success rate of doubly fed induction generator during the grid fault especially unsymmetrical grid fault of great value. Based on an improved crowbar control strategy, this paper designs a new control circuit, optimizes the control process, and improves its control speed. Finally, the simulation of MATLAB/Simulink shows that the rationality of this control circuit.
