“…Thus, the generator can be operated over a wide speed range and also the over rating of the power converter can be eliminated. The diode bridge rectifier employed at the generator terminals helps in reducing the reactive power burden on the excitation capacitor banks, since the displacement factor at the input side of this uncontrolled rectifier is unity [19,22]. The novelty of the present paper lies in the application of controlled PWM inverter with simple analog based closed loop hysteresis current controller (HCC) for the CEIG.…”

A system consisting of a capacitor-excited induction generator (CEIG) with associated power electronic converters has been developed for supplying power to a micro-grid. The power fed to the grid from the CEIG is controlled using a diode bridge rectifier (DBR) and a pulse width modulated (PWM) inverter, connected between the generator terminals and the grid. A simple analog based hysteresis current control (HCC) technique has been employed in which the current control of the PWM inverter alone needs to be carried out by sensing the current and voltage at the grid terminals. The successful working of the system has been demonstrated for three different patterns of feeding power to a micro-grid, by experiments conducted on a three-phase 230 V, 3.7 kW CEIG, with a 100 µF delta connected excitation capacitor bank and employing the controllers fabricated in the laboratory. The grid power is represented as an equivalent load resistance in the steady-state equivalent circuit of the CEIG and the technique of genetic algorithm (GA) has been adopted for the analysis of the proposed system. The predetermined performance characteristics of the system and the results of Matlab/Simulink simulation studies have also been presented.

“…The three diodes shown in series with the IGBTs are meant for blocking the reverse current flow through the inbuilt diode in the IGBTs, i.e., to provide unidirectional current conduction. The dc power output from the semi-converter is fed to the inverter through a dc link inductance [14,15]. This inductance is used to obtain a steady direct current from the SC.…”

A Self Excited Induction Generator (SEIG) system has been proposed for supplying power to the grid through a combination of a three-phase semi-converter (SC) and a line commutated inverter. This system is capable of operating at variable speed to enable maximum power, proportional to the cube of the wind speed, to be extracted from the wind. The method of analysing the system has been explained by deriving the relevant expressions for the various performance quantities. The different control schemes to be adopted for the SC to suit the various speed ranges of the generator has been described with an example along with the predetermined performance characteristics of the system, following cube law power curve. The simulated waveforms of voltage and current at the various stages of the proposed system are also presented.

in part I and part II, proposes modeling, analysis and control of a small scale wind energy conversion system employing a direct driven Flux Reversal Generator (FRG) connected to the micro grid through a quasi-Z-source inverter (QZSI). The application of QZSI using FRG to feed micro grid is proposed for the first time in this research work. The QZSI can realize buck/boost, inversion and power conditioning in a single stage with improved reliability. Also it features a wide range of voltage gain which is suitable for applications in wind systems, due to the fact that the wind generator output varies widely with wind velocity. In addition, the modified space vector PWM (SVPWM) technique is proposed in this paper to satisfy the shoot-through characteristic of QZSI. This also adds to the contribution of this research work. In this part I of this full research, modelling of the small scale FRG for wind system using Finite Element Analysis (FEA) is presented. The major parameter of FRG viz, voltage, current, torque and power are analyzed, validated and then represented in d-q model. The simulation results are validated with the analytical results. An experimental set-up to run the full procedure reported in this paper. These results form the basis for part II of this research work.
