详细说了双馈风机三相短路时的情况，并且着重分析了短路电流的表达形式以及最大值出线时刻，在此基础上提出了Crowbar电阻的取值方法。-In case of three-phase short circuit fault occurring at the terminal of a doubly-fed induction generator ( DFIG ), the rotor current characters of DFIG are analyzed from the viewpoint of the flux linkage, and the expression of the rotor
current is deduced together with the estimated expression of the
maximum rotor current. Based on above analysis, the max rotor currents and their appearing times with different Crowbar resistances are found, and the appropriate Crowbar resistance value is set for the 1.5 MW DFIG.
