In this paper original analytical models to determine the electromagnetic performances of segmented permanent magnet synchronous machines (with removed active parts in the stator or the rotor) are presented. These models are adapted to PMSM with large air gap width, large diameter, a high number of poles and large angular gaps. This method based on analytical approach is validated by comparizon with a 2D Finite Element calculation (Altair FluxTM 2D) for the specifications of a large diameter, low speed tidal high power current turbine generator. The presented method allows fast and accurate evaluation of the performances of this kind of particular machine and can be used in a systematic design process.

With the use of the discrete Fourier transform (DFT), the study provides a compact relation to calculate the winding factor of any winding distribution among regularly space-shifted slots. The new expression is general, meaningful and particularly easy-to-compute. The phase winding layout is represented with a distribution vector whose length equals the slot number: each component corresponds to a slot and indicates the proportion of conductor allocated to the considered phase (forward turns positively counted and backward turns negatively counted). From winding factor definition, mathematical developments allow to demonstrate that, in any case, the winding factors simply relate to the DFT of the distribution vector: each component of the DFT vector corresponds to a space harmonic order and equals the so-called complex winding factor. The module of the complex winding factor is the usual winding factor while the angle of the complex winding factor reveals the magnetic axis position for the considered space harmonic.

If multi-phase machines equipped with tooth-concentrated winding with half a slot per pole and per phase offer interesting characteristics (simplified manufacturing, no space subharmonic, fault-tolerant ability), their low fundamental winding factors make their designs and controls challenging. The paper addresses the case of a seven-phase Surface-mounted Permanent Magnet (SPM) machine which has a fundamental winding factor lower than the third. This so-called bi-harmonic specificity is considered in order to achieve good torque quality (average value and ripples). Regarding the design, the magnet layer is segmented into two identical radially magnetized tiles that cover about three-quarters the pole arc. Regarding the control, the rated Maximum Torque Per Ampere (MTPA) supply strategy (h1h3 control) aims at generating a third harmonic current component greater than the fundamental. A prototype has been manufactured: the ability of the machine to provide smooth torque is experimentally confirmed through the implementation of a simple MTPA control which copes with high distortion in no-load voltage.

This paper addresses the implementation of a fault-tolerant control for a seven-phase Surface-mounted PM machine (with tooth-concentrated winding to improve the fault tolerant ability). At any time, for a given torque demand, from off-line estimated electromotive force, an inherently fault-tolerant Maximum Torque Per Ampere control strategy calculates the reference currents taking into account the number of available phases. According to preliminary simulations, building the computed electromotive force with harmonics one, three and five appears as a good compromise between torque ripple reduction and peak current mitigation in safe and open-circuit fault operations. Experimental tests confirm these results.

For three-phase induction machines supplied by sinusoidal current, it is usual to model the n-bar squirrel-cage by an equivalent two-phase circuit. For a multiphase induction machine which can be supplied with different harmonics of current, the reduced-order model of the rotor must be more carefully chosen in order to predict the pulsations of torque. The proposed analysis allows to avoid a wrong design with non-sinusoidal magnetomotive forces. An analytical approach is proposed and confirmed by Finite-Element modelling at first for a three-phase induction machine and secondly for a five-phase induction machine.

This paper investigates modeling, control and power management aspects of tidal energy conversion system (TECS) with an energy storage system (ESS) unit connected to an islanded grid. The model presented in this work takes into account entire conversion system including machine, AC-DC converter, DC-AC converter, DC-DC converter and supercapacitor-based energy storage system. A dynamical modeling of the complete TECS is achieved using the graphical formalism Energetic Macroscopic Representation (EMR) and inversion-based rules are used for the control development. In addition to the modeling and control of TECS, a simple algorithm to manage the power flows between the system components is proposed. The proposed algorithm ensures the slope limitation of the active power supplied to the grid and maintains the state of charge of the supercapacitor at acceptable levels. The performances of the overall grid-connected TECS with ESS are evaluated based on tidal current data from the Ushant Island.

Multiphase induction machines have the advantage of producing torque under different current harmonics. Theoretically, with some simplifications, the maximum produced torque can be considered proportional to the harmonic winding factor related to the injected current harmonic. However previous work has shown that this theoretical proportionality between the maximum developed torque and harmonic winding factors is not obtained in the case of a five-phase induction machine with eight-poles and fractional-slot tooth concentrated winding. This paper aims to investigate the effect of winding parameters, especially phase number, fundamental polarity and stator slots number, on the torque production in multiphase induction machine under harmonics injection. A comparative study is done between four five-phase winding configurations, with the same geometry and copper volume, under both first and third harmonic injection. Finally, a special 15-phase winding presenting better consistency between maximum developed torque and harmonic winding factors is proposed.

This paper deals with a design methodology of permanent magnets (PM) generators used for fixed-pitch tidal turbines in a marine renewable energy context. In the case of underwater turbines, fixed-pitch tidal turbines could be very attractive and interesting to reduce maintenance operation by avoiding using such a complex electromechanical system for blade- pitching. In this technological case, one of the main control challenges is to ensure power limitation at high tidal current velocities. This control mode can be achieved using the generator flux-weakening. In this context, this paper proposes an original and systemic design methodology to optimize the generator design taking into account the tidal turbine power limitation for high tidal currents velocities.

To smooth the power fluctuations induced by marine current speed and to satisfy standard grid constraints, the tidal current turbine system should be combined with an energy storage unit (ESU). However, adding ESU into the existing system results in a complex structure of the entire electromechanical conversion chain that needs appropriate tools for system modeling and control development. For that purpose, this paper focuses on the use of a graphical tool based on energetic macroscopic representation (EMR) in order to model the system and design control schemes of a grid-connected tidal current turbine system including a supercapacitor-based energy storage. The transcription of EMR to Matlab/Simulink environment through the available EMR library allows a simple development of overall system control using the inversion-based rules. Simulation results, obtained from the developed simulator, are shown and discussed.

This paper presents a new analytical model to determine the cogging torque of stator-segmented permanent magnet machines (with angular air gaps, i.e. flux barriers, located in the stator). Basically, if the saturation is not considered, the cogging torque can be seen as the sum of two independent contributions: the first contribution results from the cogging torque related to an equivalent slotless machine with a single gap, the second resulting from an equivalent non-segmented slotted machine. For the specifications of a marine current turbine generator, this analytical approach is evaluated and compared with a numerical 2D Finite Element Analysis (Flux™ 2D by Altair).

In this paper, a general and compact formulation is established to predict the space harmonics generated by any symmetrical multi-phase winding (if saturation and end-effects are neglected). With the introduction of the space harmonic groups, the current sequence where a given space harmonic originates from can be determined. The speed of a space harmonic depends on the electrical frequency of the originating current supply. Two time harmonics belonging to the same sequence will generate the same wave train but with different speeds. The method is successfully applied to several multi-phase integral-slot, 1st grade and 2nd grade fractional-slot winding distributions (single-layer and double-layer). As fundamental results, for a given sequence, the present space harmonic orders only depend on the slot, pole, phase and base slot numbers.

Assessing the reliability of power electronic converter systems is an essential task. New generations of components and topologies will be deployed in industrial segments such as renewable energy and electric vehicles. Although the lack of experience feedback, the reliability of those converter systems may be estimated by assessing stress profile and using physics-of-failure models. This method is used in the assessment of a wind turbine converter reliability including the effects of the uncertainty in the lifetime model parameters. By using Monte Carlo method, this paper exhibits the strong impact onto the reliability function of the input parameters although their weak scattering.

The paper investigates the effect of the bar number on the performances of a five-phase squirrel-cage induction machine with fractional-slot tooth concentrated winding. With a same stator, five different rotor bar numbers are chosen and the rotor magnetic circuits are designed using an analytical approach. Then, a finite-element analysis is done under two different supply conditions: fundamental currents and third harmonic currents. Finally regarding the used winding specificities the possibility of second harmonic current supply is evaluated. The results are presented in a comparative way in order to determine the impact of rotor bar number on torque quality for the different supply modes.

This paper addresses the estimation of the 3D air gap field for Ironless Rotor Double Stator axial flux Permanent Magnet machines: the described method is based on a coulombian representation of the Permanent Magnets and the mirror theory. This approach can take into account the significant 3D effects that can occur in machine with very large air gap (that might be used in wind or tidal energy harnessing). For validation purpose, a laboratory prototype has been manufactured, the machine being characterized by the possibility of changing the air gap values. For several air gap values, experimental and calculated no load voltages are in good agreement, thus showing the ability of the focused calculation method to evaluate the performances of these particular machines.

The paper addresses the design of a seven-phase Surface-mounted Permanent Magnet (SPM) machine with tooth-concentrated winding. As the fundamental winding factor is lower than the third, the rated control strategy aims at generating a third harmonic current component greater than the fundamental. For this control, the magnet layer is designed with the constraint of maximizing the average torque and minimizing the ripple torques. Solutions where the pole consists of several identical radially-magnetized magnets (regularly space shifted along the pole arc) are explored: designing the rotor with two identical radially magnetized magnets that cover about three-quarters the pole arc appears as the best solution. In addition, fifth harmonic current injection can be performed to slightly enhance the torque without increasing the ripples. 2D FEA confirms these results. Furthermore, according to analytical approach, positive impacts on some parasitic effects (as the radial stress and the magnet losses) are expected.

In the context of traction drives with required torque transient capabilities and a classically wide flux weakening speed range, this paper gives design considerations of a particular Double-Polarity (DP) five-phase machine. Beyond its intrinsic fault tolerance due its five phases, it specificity is the ability to develop torques of comparable values under three kinds of supply: with only first, third or both first and third sinusoidal currents. This property, due to first (E1) and third (E3) harmonic electromotive forces (emf) of comparable values, gives more degrees of freedom for the control of the machine. Unlike three-phase sinusoidal machine, flux weakening is no more the unique solution when maximum voltage is reached. Design considerations of such DP machines are presented: firstly, elements for the choice of slots/poles combination are given; secondly, in case of an Interior Permanent Magnet Synchronous Machine, possible adaptations of the rotor are proposed; thirdly, the level of eddy-current losses is considered, important at high frequencies. For proof of the concept effectiveness, a prototype with a five-phase fractional-slot concentrated winding of 40 slots and 16/48 poles is presented with results from experimental set-up and Finite Element modeling. A comparison with equivalent three-phase 24-slot/16-pole machine is also carried out.

This paper addresses the design of a bi-harmonic five-phase Surface-mounted Permanent Magnet (SPM) machine for marine propulsion. The bi-harmonic characteristic results from the particular 20 slots-8 poles configuration that makes possible high value of third harmonic current injection. Thus the machine performance can be improved in terms of average torque, speed range, losses control and torque quality, this last feature being the scope of the paper. As low ripple torques are wanted at low speed, the magnet layer is defined to reduce the cogging torque and to make third harmonic current injection increasing average torque and reducing pulsating torque in the same time. According to a selection procedure based on the numerical simulations of a high number of machines, it appears that designing the rotor with two identical radially magnetized magnet that cover two-third the pole arc allows to reach this goal. Referring to an equivalent three-phase machine, the torque ripple level of the bi-harmonic five-phase machine is more than three times lower, thus being obtained with a simple control strategy that aims at achieving constant currents in the rotating frames. The time simulations of the drive confirm the significant reduction of the speed oscillation, especially at low speed.
