“…Authors in [15] have proposed a variable DC (VDC) SPM control, in which the band limiter and its current feedback sensors are not required, since regulating voltage is proportionally comparable to back emf and speed. VDC control operates in SPM mode throughout the speed range, in which current is maintained within the operating range by varying turn‐on and turn‐off angles [15]. Speed dependent variable DC‐link voltage‐based SPM control in PV‐fed WPS is presented in [9], where the variable DC‐link voltage is regulated from PV source by an intermediate DC–DC converter for MPPT tracking as shown in Fig.…”

Variable speed drives (VSDs)‐based direct photovoltaic (PV) fed water pumping systems (WPS) are of increasing importance for the socio‐economic growth in remote areas. Due to the absence of windings and magnets on the rotor, switched reluctance motor (SRM) is emerging as a viable economic alternative in VSD systems. Thus, this study proposes and presents a simplified pulse width modulation‐based maximum power point tracking (MPPT) control for direct PV‐fed SRM‐WPS using modified lookup table (MLUT) approach. The proposed control technique offers lesser phase peak, near same phase rms, reduced torque ripple and noise, better efficiency and reduced DC‐link current ripple in contrast to single pulse mode technique. In addition, the proposed system does not require an intermediate converter and current sensors. Thus, results in reduced noise, reduced size and hence the cost of WPS. Further, it also provides a reduced memory size due to MLUT and an effective MPPT with the good dynamic response for a change in atmospheric conditions. The proposed system is modelled and simulated in MATLAB/Simulink environment and the prototype is built to validate experimentally using field programmable gate array controller. The performance analysis of the proposed system has been carried out and presented.

“…The majority of existing papers referring to the analysis of wind energy systems [3][4][5][6][7][8], use simulation tools that are more focused on the detailed simulation of the control system rather than the machine. Consequently, in most of the cases Matlab/Simulink is used as a simulation tool.…”

The purpose of this paper is the performance investigation of a Permanent Magnet Synchronous Generator (PMSG) system, suitable for wind power applications and the comparison of the machine electromagnetic characteristics under open and closed control loop implementations. The copper and iron losses are estimated and compared for the above control systems with the use of the Steinmetz-Bertotti loss separation equation. In addition, the effect of the rotating magnetic field on the total losses is studied. The generator is simulated using Finite Element Analysis (FEA), while the rest of the components are connected to the machine model using a drawing window of the FEA software and suitable command files. The close loop control used in the present study results to less losses and greater machine efficiency. The main novelty of the paper is the simulation of the PMSG coupled with a converter and control schemes using FEA, which ensures more accurate results of the whole system and allows the detailed machine electromagnetic study, while the majority of existing papers on this topic uses simulation tools that usually simulate in detail the electric circuits but not the machine. The FEM model is validated by experimental results.

“…In a comparative study of electrical generators fitted to wind turbine systems, the authors in [5] conclude that the PMSG seems to be the most adapted candidate as illustrated in the Table 1 below taken from this reference, where the evaluation is based in the main characteristics of the WECS, each them is graded from 1 to 5 points. Recently, due to numerous advantages (simple structure, robustness, high performance, low cost), an innovative variable reluctance generator (VRG) [6][7][8][9][10][11][12][13][14] has been recognized to have potential for wind power applications. This explains our interest in the study of this type of generator.…”

Based on exhaustive review of the state of the art of the electric generators fitted to Wind Energy Conversion System (WECS), this study is focused on an innovative machine that is a Variable Reluctance Generator (VRG). Indeed, its simple and rugged structure (low cost), its high torque at low speed (gearless), its fault-tolerance (lowest maintenance), allow it to be a potential candidate for a small wind power application at variable wind speed. For better accuracy, a finite element model of a studied doubly salient VRG is developed using open source software FEMM to identify the electromagnetic characteristics such as linkage flux, torque or inductance versus rotor position and stator excitation. The obtained data are then transferred into look-up tables of MATLAB/Simulink to perform various simulations. Performance of the proposed wind power system is analyzed for several parameters and results are discussed.
