摘要：

This paper derives the transients between the grid voltage and the rotor current of doubly-fed induction generator (DFIG) under grid voltage symmetric swell. An effective control strategy aiming to restrain rotor over-current is proposed and the traditional control strategy of the grid-side converter is also improved. Without adding any other power electronic devices, the proposed method with both the rotor current suppression (RCS) and the grid voltage suppression (GVS) can not only solve the problem of short-circuit of the rotor side converter resulting from the frequent switching of the Crowbar device, but also maximally improve the capability of wind turbine in dynamic reactive power support. This control strategy can make sure that the wind turbine is able to maintain its normal operation even during the fault and at the same time the high voltage ride through (HVRT) capability of wind turbine can be achieved. As a result, the operation reliability of the wind turbine is significantly improved. Finally, the simulations and analysis results in the PSCAD/EMTDC verify the effectiveness and feasibility of the proposed control scheme. © 2020, Power System Technology Press. All right reserved.
