After supporting system frequency, when regaining the rotor speed, the existing recovery researches are unable to achieve the counterbalance between the depth double frequency drop (DFD) and rotor speed recovery performance. To overcome this issue, firstly, the influence of the amount of the power reduction on the DFD and the speed recovery performance is quantified in this paper; secondly, a recovery strategy of DFIG based on PI controller is proposed, in which the active power reduction with output characteristics of “rising after restraining” is preliminary constructed. Then, in order to compensate the shortcomings of the fixed-PI-coefficient based speed recovery strategy; the dynamic-PI-coefficient based speed recovery strategy is addressed to ensure the rapid speed recovery performance while suppressing the depth of DFD. Finally, a system with various wind power penetrations and speed conditions is conducted to indicate the effectiveness of the proposed rotor speed recovery strategy.
