| Abstract: | An improved short-term overload control strategy of DFIG is proposed.Firstly,the basic theory and operation characteristics of DFIG are expounded.Then the working principle and limitations of the short-time overload control mode of DFIG wind turbines are analyzed.The hidden trouble of excessive release of rotor kinetic energy and the phenomenon of secondary frequency drop are analyzed.An improved short-time overload control strategy is proposed,and 3-machine 9-node system model is built by using Matlab/Simulink for simulation.The results verify the effectiveness to improve transient frequency response. |

| Keywords: | DFIG virtual inertia control secondary frequency drop frequency modulation frequency stability |
