The paper proposes a novel fault ride-through (FRT) configuration with a transient management scheme to provide dynamic grid supports for self-excited induction generator (SEIG)-based wind turbines. The new configuration is capable of supporting both shunt and series compensation modes for enhancing FRT capability and transient stability. The proposed control scheme, utilizing positive and negative sequence controllers, provides a transient management solution for both balanced and unbalanced fault conditions. An active damping control loop for the shunt compensation configuration is developed to mitigate system oscillation and improve system performance during and following faults. A comprehensive simulation has verified the FRT capability of the new configuration and transient management scheme, and showed that the proposed topology increases system stability under various short circuit ratios, even in case of a weak grid. The experimental results are also carried out to show the effectiveness of the proposed shunt-series reconfiguration topology.
