“…The pole pitch must be sufficiently large for the substantial diameter-specific design, so a larger number of parts and windings make this heavyweight and costly. Furthermore, it is important to energize the rotor winding with DC, utilizing slip rings and brushes, or brushless exciter, utilizing a rotating rectifier, and the field losses are unavoidable [31].…”

Transverse flux permanent magnet (TFPM) machines are a potential candidate for directdrive wind power application due to high torque and power densities. The operating principle of TFPM machines is firstly described with various topologies available in literature, with the placement of magnets as a criterion for the classification of TFPM machine topologies. This review includes characteristics, power factor improvement, cogging torque minimization, material consideration, modelling techniques, and scalability. Different wind turbine concepts with direct-drive machines, control techniques and power converter topologies are also considered in this paper. INDEX Permanent magnet, topologies, transverse flux, and wind power.

“…• The BDFRG is almost fully-saturated by the grid-tied primary winding, so L m , and hence L p = L m + L lp , can hardly change making (16) and (17) insensitive to their on-line variations. This is further reinforced by the comparatively higher leakage inductances (L lp ) intrinsic to the machine [10,11].…”

“…brushless doubly fed induction generator (BDFIG)) can be of special nested-loops cage or wound structure with short-circuited coils [1,2,8,9], whereas its cage-less reluctance companion, the brushless doubly-fed reluctance generator (BDFRG), may have an axially or radially laminated design [10,11] offering the superior efficiency, fewer parameter-dependent dynamic models [12], and the possibility for decoupled field-oriented control of real and reactive power [13,14] similar to DFIG [4]. More optimised hybrid rotor prototypes of higher torque densities and efficiencies have likewise been reported recently to combine the individual BDFIG and BDFRG advantages in a single machine [15][16][17]. Besides, the usually 30% rated 'backto-back' converter of the BDFG is not only cheaper but less susceptible to failures than its full-scale version with synchronous wind turbine generators [18], sharing so the DFIG's economic benefits in this sense [19].…”

“…A modern cage-less reluctance rotor version of the BDFG, the brushless doubly-fed reluctance generator (BDFRG), presented in Figure 1 is particularly promising [10,11]. It can offer better efficiency, facilitated less parameter dependent dynamic modelling and much simpler control compared to the cage induction rotor counterpart with nested-loop structures [12][13][14].…”

A new model reference adaptive system based estimation technique for vector control of real and reactive power of a brushless doubly fed reluctance generator without a shaft position sensor is proposed. The rotor speed is being precisely observed in a closed‐loop manner by eliminating the error between the measured and estimated inverter‐fed (secondary) winding current angles in a stationary frame. Contrary to the existing model reference adaptive system observer designs reported in the brushless doubly fed reluctance generator literature, the reference model is entirely parameter‐free and only utilises direct measurements of the secondary currents. Furthermore, the current estimates coming from the adaptive model are obtained using the measured voltages and currents of the grid‐connected (primary) winding, which has provided prospects for much higher accuracy and superior overall performance. The realistic simulations, preliminary experimental results, and the accompanying parameter sensitivity studies have shown the great controller potential for typical operating conditions of variable speed wind turbines with maximum power point tracking.
