“…(The 8-pole winding is the power winding, which is wounded in the inner side of the stator, while the 4-pole winding is the control winding, which is wounded in the outer side of it).

“…The operation of BDFRM under different conditions, such as the capability of generating reactive power for voltage drop considerations [79], open-circuit [82], and unbalanced grid voltage [83], is investigated. All grid-tied wind turbine generators must be compatible with locational system codes, as well as the reactive power considerations, and thus, need to be evaluated under grid-tied performance in the understudy zones.…”

“…The accuracy of the results is justified by testing the machine and afterward compared with the FEA machine design. In [83], a mathematical model for a BDFRG under unbalanced grid voltage is introduced. Based on the sequence components, the machine EEC in the d-q reference frame is presented, and the torque, as well as the power formulations, are extracted.…”

The Brushless Doubly-Fed Reluctance Machine (BDFRM) has been widely investigated in numerous research studies since it is brushless and cageless and there is no winding on the rotor of this emerging machine. This feature leads to several advantages for this machine in comparison with its induction counterpart, i.e., Brushless Doubly-Fed Induction Machine (BDFIM). Less maintenance, less power losses, and also more reliability are the major advantages of BDFRM compared to BDFIM. The design complexity of its reluctance rotor, as well as flux patterns for indirect connection between the two windings mounted on the stator including power winding and control winding, have restricted the development of this machine technology. In the literature, there is not a comprehensive review of the research studies related to BDFRM. In this paper, the previous research studies are reviewed from different points of view, such as operation, design, control, transient model, dynamic model, power factor, Maximum Power Point Tracking (MPPT), and losses. It is revealed that the BDFRM is still evolving since the theoretical results have shown that this machine operates efficiently if it is well-designed.

“…Under unbalanced conditions, negative-sequence components are present in the grid voltage, causing problems for wind generators such as unbalanced primary currents, current harmonics at the secondary side, unequal heating, or hot spots in the windings [30] which degrade the insulation and reduce the life expectancy of the windings, as well as producing power pulsations [31,32]. Unbalanced currents also create a pulsating torque, which may cause extra mechanical stress on the drive train and gearbox [33][34][35][36] and increase acoustic noise, too. Therefore, studying wind generators under unbalanced grid voltage conditions and designing a convenient control strategy are very important.…”

Dynamic Modeling and Control of BDFRG under Unbalanced Grid Conditions

The Brushless Doubly-Fed Reluctance Generator (BDFRG) is a potential alternative to the Doubly Fed Induction Generator (DFIG) in wind power applications owing to its reasonable cost, competitive performance, and high reliability. In comparison with the Brushless Doubly-Fed Induction Generator (BDFIG), the BDFRG is more efficient and easier to control owing to the cage-less rotor. One of the most preferable advantages of BDFRG over DFIG is the inherently better performance under unbalanced grid conditions. The study conducted in this paper showed that conventional vector control of the BDFRG results in excessive oscillations of the primary active/reactive power, electromagnetic torque, and primary/secondary currents in this case. In order to address such limitations, this paper presented a new control strategy for the unbalanced operation of BDFRG-based wind generation systems. A modified vector control scheme was proposed with the capability to control the positive and the negative sequences of the secondary currents independently, thus greatly reducing the adverse implications of the unbalanced supply. The controller performance has been validated by simulations using a 1.5 MW BDFRG dynamical model built upon the positive and negative sequence equations. The main benefits of the new control strategy are quantified in comparison with conventional PI current control design.
