Abstract This paper analyzes the transient behavior of a doubly fed induction generation (DFIG) with split rotor windings during grid voltage dips. By changing the number of the turns of the rotor windings,the rising current can be limited and therefore the low voltage ride through (LVRT) ability can be achieved. A dynamic model based on Matlab Simulink is built to evaluate the LVRT capability on both full voltage dip and partial voltage dip occasions,and to discuss the value of n(turns changing parameter) for the influence on the LVRT capability. The effect of non the performance of DFIG is different under different voltage dip occasions. Finally,the test results of a DFIG prototype (7.5kW) are presented to prove the idea.
