This paper proposes an optimized and coordinated model predictive control (MPC) scheme for doublyfed induction generators (DFIGs) with DC-based converter system to improve the efficiency and dynamic performance in DC grids. In this configuration, the stator and rotor of the DFIG are connected to the DC bus via voltage source converters, namely, a rotor side converter (RSC) and a stator side converter (SSC). Optimized trajectories for rotor flux and stator current are proposed to minimize Joule losses of the DFIG, which is particularly advantageous at low and moderate torque. The coordinated MPC scheme is applied to overcome the weaknesses of the field-oriented control technique in the rotor flux-oriented frame, which makes the rotor flux stable and the stator current track its reference closely and quickly. Lastly, simulations and experiments are carried out to validate the feasibility of the control scheme and to analyze the steady-state and dynamic performance of the DFIG.

“…As an alternative, the Doubly Fed Induction Generator connected to a diode rectifier on the stator and excited by a low power PWM converter through the rotor can be used, where both the diode bridge and the rotor converter are connected to the same dc grid: such a layout has been recently proposed in [8]- [9]. It should be noticed that the reduction of the cost of power electronics, which is the main reason for which DFIGs are widely used in ac wind energy conversion systems [10]- [12], is further pursued in this configuration, because one-less PWM converter is needed.…”

“…In [8], a Field Oriented Control (FOC) which regulates the average dc power by acting on a suitable fraction of the rotor flux linkage has been proposed, with the aim to tune the commutation inductance in such a way to minimize the derating of the DFIG due to the current harmonics. In [9], a FOC in the stator flux linkage frame has been suggested.…”

Summary This paper addresses the diagnosis of open‐switch fault in pulse‐width modulation (PWM) power converter based on insulated‐gate bipolar transistor (IGBT) used in doubly‐fed induction generator‐direct current (DFIG‐DC) system. The fault diagnosis is carried out by analyzing the rotor currents within healthy and faulty operation conditions. In the new proposed configuration of DFIG connected to DC‐bus, the diode rectifier is employed to connect the stator windings to the DC‐bus and the PWM power converter is employed to connect the rotor windings to the DC‐bus. The main goal of using a PWM power converter is to keep the stator voltage and frequency constant at rated values. In this regard, the various experimental results for open‐circuit faults are obtained by using dSpace DS1104 control board. Some experimental results are obtained, proving the effectiveness of the proposed diagnosis approach such as low detection time and high robustness against false alarms.
