“…The proposed controller in [44] is robust to uncertainties toward parameter variations and achieves the constant converter switching frequency by using space vector modulation. In [45], the DPC based on the twelve sections has been adopted to implement the power tracking of the openwinding BDFIG system as illustrated in Fig. 5.…”

The brushless doubly-fed generator (BDFG) is a kind of dual-electrical-port field-modulated electrical machine containing two sets of stator windings with different pole pairs. The stator power winding undertakes most of the power inflow and outflow, and the stator control winding connected to the power converter can be utilized to regulate the machine operation status. Consequently, the rotor no longer needs to be supplied by the power converter, so that the brushes and slip rings can be removed. The BDFG can be used for grid-connected power generation as well as standalone power generation. This paper reviews recent advances of control technologies for BDFGs under different operation conditions, e.g., gridconnected ac power generation with normal and faulty grids, standalone ac power generation with normal and special loads, and dc power generation. The progresses of sensorless control technologies for BDFGbased power generation systems are also discussed. The classification and comparison are carried out to discover the similarities and differences between theses control technologies. This paper is in the hope of inspiring new, ground breakings and progresses for high-performance BDFG power generator applications.

“…Enormous efforts have been put in the advancement of WECS, to reduce costs, increase the efficiency and the reliability [1,2], with the sustained and rapid growth of world economy, the energy demand is increasing day by day, but a large amount of fossil fuel is used to lead to the environmental pollution aggravation. The wind energy as a clean and renewable energy accords with the future energy development [3]. The permanent magnet synchronous generator and the doubly fed induction generator based of WECS (PMSG WECS, DFIG-WECS) has become the most popular configuration for wind energy applications on one hand, The DFIG has several advantages including the maximum power capture over a wide speed range and decoupled active and reactive power control.…”

This paper deals with the control aspect of the brushless doubly fed induction generator, 'BDFIG' incorporating in a wind energy conversion system, 'WECS'. The control process may divide in two main parts control of machine side converter, MSC' and grid side converter, 'GSC'. Control process adopts direct power control, DPC approach thanks to its robustness and implementation simplicity direct power control permits decoupled regulation for active and reactive powers and as well pretty good robustness and performance during transient and steady state operation without PI regulators and rotating coordinate transformations. The regulation of power flow toward supply network via stator is performed using conventional direct power control at level the machine side converter where the active power reference signal is tuning depending to the output of the MPPT unit and the reactive power reference signal is set to zero to ensure unity power factor operation. Meanwhile, control of power flow between grid and grid side converter, 'GSC' is done using improved direct power control based virtual flux and Second order generalized integrator - frequency locked loop, 'SOGI-FLL' estimator in order to estimate frequency and angular position of voltage grid vector and as well power flow has been analysed during various operation conditions, 'synchronous, sub synchronous and super synchronous speeds'. The obtained simulation results show satisfactory system operation in terms of robustness and optimum power tracking behaviour and good steady state stability and finally reasonable settling time during transients.
