“…frequency), 3.7 kW, delta-connected squirrel-cage induction machine has been considered for the analysis of the proposed WECS. A delta connected capacitor bank of 100-lF per phase has been chosen for operating the induction machine in self-excited mode [8,10,13]. For this value of capacitance, the machine delivers its rated power with a voltage of 230 V at rated speed of 1500 rpm (1 p.u.…”

“…In such systems, squirrel-cage induction machines functioning as generators are being used due to their low cost, simple, robust construction and almost nil maintenance requirements [5][6][7][8][9][10][11][12]. This machine can be operated either as a grid-connected induction generator for supplying power to the grid or selfexcited induction generator (SEIG) for feeding power to the isolated loads.…”

“…A smoothing inductor is connected in between the output side of semiconverter and dc microgrid to have the continuous dc grid current. In the case of SEIG, the output voltage and frequency vary with the driving speed and load [5][6][7][8][9][10][11][12][13][14]. For the present system, this variable voltage and variable frequency (VVVF) output from SEIG is fed to the three-phase semi-converter.…”

a b s t r a c tNowadays, there is an increased emphasis on utilizing the renewable energy sources and selection of suitable power converters for supplying dc microgrid. Among the various renewable energy sources, wind energy stands first in terms of installed capacity. So, an attempt is made in this paper for supplying dc microgrid utilizing wind energy. A self-excited induction generator has been used in the proposed wind energy conversion system (WECS). A single-stage power converter, namely, semi-converter is connected between the SEIG and dc grid terminals for closed-loop control of the proposed system. A perturb and observe (P&O) based maximum power point tracking (MPPT) algorithm has been developed and implemented using a dsPIC30F4011 digital controller. In this MPPT algorithm, the firing angle of the converter is adjusted by continuously monitoring the dc grid current for a given wind velocity. For analyzing the proposed system, a MATLAB/Simulink model has been developed by selecting the various components starting from wind-turbine model to the power converter supplying dc microgrid. Successful working of the proposed WECS has also been shown through experimental results obtained on a prototype model developed in the laboratory.

“…Furthermore, it is to be noted that (i) the magnetising reactance X m and the core loss resistance R m vary with the speed and load and (ii) as seen from (1), the generated frequency f g depends not only on the speed but also on the parameters of the generator and load. So in this paper, a technique based on genetic algorithm (GA), proposed more recently by Karthigaivel et al [25,26] is adopted.…”

“…The measured parameters of the generator are R 1 = 1.30 Ω, R 2 = 1.75 Ω, X 1 = X 2 = 2.6 Ω, the rated stator phase current being 9.0 A. The (E/a) against X m and (R m /a) against (E/a) characteristics were obtained experimentally at the rated frequency of 50 Hz, following the procedure described in [25]. Using the curve fitting algorithm available in Matlab, these relationships were expressed as sixth order polynomials as …”

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.
