Abstract

The RSC is generally controlled by using PI controller, but its narrow bandwidth and slow transient response speed limit the LVRT capability of DFIG. So, a LVRT strategy-based multi-controller switching is proposed in this paper. According to different rotor current setting value, the corresponding control strategy of RSC is implemented. That is, the PI controller is used during normal PCC voltage. However, during PCC voltage sag, the control strategy is switched to FLHCC when the rotor current reaches the first setting value, and a set of resistors is connected into the rotor circuit when the rotor current reaches the second setting value. In addition, the FLHCC implementation, the control strategy switching and the series resistance determination are also introduced in detail. Finally, the feasibility of the proposed LVRT strategy is verified by the dynamic simulation.
