The stability of a wind turbine-rotated synchronous generator must be maintained during a sudden change in wind speed or direction. In integral slot winding machines this task is taken care of by rotor damper windings. Tooth-coil permanent magnet generators cannot, however, have a damper winding in the rotor because of the high harmonic content of the air gap. In this paper, we study a possibility to stabilize PMSG damperless synchronous operation by dividing the generator stator winding into two parts -power winding (PW) and control winding (CW). We call this machine a dual-port PMSG (DPPMSG). The PW is directly connected to the grid. Therefore, the generator rotates, in average, at a fixed speed. On the other hand, the CW is connected to the grid through a four-quadrant power converter. The CW has three different tasks: It is responsible for the startup process, damping of speed oscillations and, of course, power generation. Electrical and magnetic decoupling of the winding sets is ensured by concentrated wound coils. The number of stator coils allocated to a winding set determines its power level. Different power levels of winding sets are analytically analyzed for wind gust speeds according to the IEC 61 400 standard. The results are verified by experimental tests.

“…This voltage waveform is shown in Figure 8. Figure 9 shows the induced torque due only to coupling between the winding sets (Ayaz et al, 2012). The peak-induced voltage of phase B2 for Type-2 owing to mutual coupling is around 4.4 V. The peak-induced voltage value of phase B2 for Type-3 is around 85 mV.…”

This paper presents a new accessory drive system for hybrid electric vehicles (HEVs). This new concept involves a dual winding electric machine with simultaneous motor and generator functions. The electric machine provides power for all accessory loads such as the steering pump, compressors and 12 V loads. When the engine is off, the electric machine starts its motoring action and provides mechanical power to the accessory loads. Simultaneously, the generator windings provide power for the 12 V loads. The proposed structure could be a viable choice for fault-tolerant applications because of the concentrated winding type that maintains electrical and magnetic isolation. Design considerations of the proposed electric machine are outlined in the paper. The distributed winding topology and concentrated winding topologies are also compared. Analytical proof of magnetic decoupling is presented and experimentally verified. E. Mese et al.

“…The overlapping nature of winding exhibits a higher mutual coupling effect making it a poor choice for the independent operation of motor and generator. For such operations, the dual winding PM machines using a specific arrangement of nonoverlapped nature have been studied in [9,10,11,12]. This type of winding benefits the shorter end windings, high slot fill factor, and flexible control to improve the performance [13].…”

Three-Phase Dual-Winding Multitasked PMSM Machine Using Double Layer Concentrated Winding for HEV Application

This paper proposes a three-phase dual-winding permanent magnet synchronous machine (PMSM) providing multitasked operation for accessory drive systems in hybrid electric vehicles (HEV). The novelty of this research lies in the machine having special slots and pole combinations with specific configuration of two sets of double-layer concentrated group winding separated by the unwound tooth between the phase groups formed on the same stator to achieve both the motoring and generator operation simultaneously as well as independently. These operations are accomplished by incorporating motor and generator winding separately on the same stator of a single PMSM machine. This single machine is particularly designed to eliminate the mutual coupling between these two sets of windings such that the load variation on the generator does not affect the mechanical output power of the motor. To confirm this multitasking, the electromagnetic design of the machine has been presented, and its operating modes are analyzed. The performance is compared using finite element analysis with that of a conventional PMSM machine having a double-layer winding configuration.INDEX TERMS Accessory drive system, double-layer concentrated winding, dual-winding machine, hybrid electric vehicles, permanent magnet synchronous machine.
