An overview of different strategies applied to enhance the fault Ride-Through (FRT) ability of the Doubly Fed Induction Generators (DFIGs)-based Wind Turbines (WTs) during transient state is introduced in the study. Different FRT strategies dependent on (a) additional protection circuit's establishment, (b) reactive power injecting devices installation, and (c) various control approaches have been proposed in the literature. Typically, during disturbance in the grid to restrict the generated rotor overcurrent and undesirable Direct Current (DC)-link overvoltage, the protection circuits or control structures are connected. Concurrently, to improve the transient performance of the DFIG-based WT, the reactive power injecting devices outperform any deficiency of the reactive power and consequently bound the DC-link voltage and current in the rotor. Actually, during the transient state without damaging its operating strategy, many research findings show a productive DFIG protection. Along these lines, this study centers around underscoring the present status of the rotor overcurrent and DC-link overvoltage protection solutions, for example, the crowbar and its related protection circuits, fault current limiter, the reactive power injecting devices, for example, the static synchronous compensators, static var compensator, and dynamic voltage restorer.

“…Essentially, the Crot converter controls the real and reactive power production of the induction machine, and the Cgrid controls the DC-link voltage and the reactive power absorbed from the grid by the converter [19]. The conventional control mechanism for these DFIG converters is based upon the decoupled d-q vector control concept, detailed in [20].…”

The connection of distributed generators in distribution systems of medium voltage or low voltage has been encouraged widely. Wind power generation in Brazil has been growing substantially in the last years. In this way, it is essential to investigate the dynamic behavior of this technology connected to the electrical grid. Among all power quality phenomenon, voltage sags are one of the main issues for the industry sector customers due to the damage caused to voltage sensitive devices largely employed in industrial applications. This paper aims to analyze the dynamic response of gridconnected doubly-fed induction generators subjected to an instantaneous voltage sag Type A, considering two rotor-side converter control topologies: Voltage Regulation and Reactive Power Regulation. The results will provide the reader a better comparative insight into the responses of these DFIG control topologies applied to a wind power system.

“…In [11], a direct torque control scheme is proposed for dc voltage regulation based on hysteresis controller and optimal switching table. In [12], a mathematical model of DFIG-DC system considering harmonic currents in rotor flux reference frame is built for the better understanding of dc voltage control and torque ripple mitigation. However, the control accuracy of all these methods is highly dependent on machine parameters due to the stator or rotor flux orientation [8]- [12].…”

This letter proposes a unified power control method for DFIG-DC system, which can seamlessly transfer from grid connected mode to standalone mode without changing control strategy and vice versa. There is no need to detect the interconnection switch to identify whether it is grid connected or standalone. The dc voltage and stator active power are both positive correlations with the magnitude of rotor current vector, which indicates that these two objectives can be combined as the unified power to generate the rotor current reference. The stator frequency can be controlled by the rotating speed of rotor current vector without calculating stator frequency which can reduce the parameter dependency. Finally, the experiments based on a 1 kW DFIG-DC setup is carried out to verify the proposed unified power control method.
