“…Figures 11(c)-11(e) illustrate that the THD measured for injected grid current and voltage is 2.4% and 2.3%, respectively, which is quite low per Standard IEEE-519 and IEC 61727. Also, it satisfies the power factor demand with a 0.996 power factor, as illustrated in Figure 11(g), and is far better as compared to power factor and THD of about 0.94% and 4.25%, respectively, in the case of the converter topology proposed for wind power applications by Oliveira et al in [5]. This demonstrates the expected improvement when compared with similar works in [3,5,18].…”

“…In [5], various power processing topologies were proposed and have investigated from time to time by different researchers. But all these suffer from the demerits of poor device utilization; the produced variable DC-link voltage causes distortion of currents and voltage of generator and has poor power factor operation.…”

This article presents the development of a novel control for matrix converter interfaced permanent magnet wind energy conversion system. Here, an adaptive fuzzy control algorithm incorporated with a reversed matrix converter is proposed to yield maximum energy with enhanced dynamic performance and low harmonic characteristics. The control algorithm is implemented using a dSPACE DS1104 real-time board (dSPACE, Paderborn, Germany). Feasibility of the proposed system has been verified through simulation and experiment results using a laboratory 1.2-kW prototype of a wind energy conversion system under dynamic conditions.

“…The same topology can also be used in an induction generator-based WECS, but it is less attractive due to the need for an external source of VAR. Employing semi-controlled rectifiers is also a possibility [64]. One problem with using a diode rectifier as the generator-side converter is the resulting distortion in the stator current waveforms, leading to higher losses and torque ripples in the generator.…”

Small-scale standalone wind turbines provide a very attractive renewable energy source for off-grid remote communities. Taking advantage of variable-speed turbine technology, which requires a partial-or full-scale power converter, and through integrating an energy storage system, smooth and fast power flow control, maximum power point tracking, and a highquality power is ensured.Due to high reliability and efficiency, permanent magnet synchronous generator seems to be the dominating generator type in gearless wind turbines, employed for off-grid applications.However, wind turbines using geared squirrel-cage induction generator (SCIG) are still widely accepted due to their robustness, simplicity, light weight and low cost. Permanent magnet induction generator, a relatively new induction-based machine, has recently been recognized in the wind energy market as an alternative for permanent magnet synchronous generator. A thorough comparative study, among these three generator types, is conducted in this research in order to enable selection of the most appropriate generator for off-grid wind energy conversion system (WECS), subject to a set of given conditions. The system based on geared SCIG has been shown to be the most appropriate scheme for a small-scale standalone WECS, supplying a remote area.Different topologies of power electronic converters, employed in WECSs, are overviewed.Among the converters considered, current source converter is identified to have a great potential for off-grid wind turbines.Three current-source inverter-based topologies, validated in the literature for on-grid WECS, are compared for off-grid WECS application. Feasibility study and performance evaluation are conducted through analysis and simulation. Among all, the topology composed of three-phase diode bridge rectifier, DC/DC buck converter, and pulse-width-modulated current-source inverter (PWM-CSI) is identified as a simple and low-cost configuration, offering satisfactory performance for a low-power off-grid WECS.A small-scale standalone wind energy conversion system featuring SCIG, CSI and a novel energy storage integration scheme is proposed and a systematic approach for the dc-link inductor design is presented. iv In developing the overall dynamic model of the proposed wind turbine system, detailed models of the system components are derived. A reduced-order generic load model, that is suitable for both balanced and unbalanced load conditions, is developed and combined with the system components in order to enable steady-state and transient simulations of the overall system. A linear small-signal model of the system is developed around three operating points to investigate stability, controllability, and observability of the system. The eigenvalue analysis of the small-signal model shows that the open-loop system is locally stable around operating points 1 and 3, but not 2. Gramian matrices of the linearized system show that the system is completely controllable at the three operating points and completely observable at...

“…Usually, the AC-DC conversion is achieved by some boost-type converter [16][17][18] which is not appropriate if a low DC-voltage is required. This paper analyses the behavior of a buck-type converter applied as a rectifier stage for such low-voltage buses.…”

Abstract:A new application of the three-phase buck-resonant converter is presented in this paper. It is shown that the analyzed converter is suitable to operate as the rectifier stage in low power wind energy conversion systems (WECS) based on permanent magnet synchronous generators (PMSG) with variable wind speed. As main features, it presents a single controlled switch, simple implementation and control, and operates with a high power factor and low harmonic distortion over all wind speed ranges. The converter topology, its design equations and its operation are presented, as well as the simulation results of the PMSG based conversion system. From the analysis carried out in the paper it is concluded that the converter is indicated to be employed in distributed generation and hybrid systems where wind generation is associated with other sources.
