Abstract Q Q Q Q A review of methods of minimum capacitance value calculation of a 3 -Ø self–excited Induction generator used to extract the power from wind have been attempted. Either induction generator used as stand-alone mode or grid connected mode of operations it require capacitors in wind power generation. Now a days grid connected induction generator require capacitor even though grid supplies the reactive volt-ampere (VAR), to avoid the voltage collapse due to heavy drain of VAR from the grid. A simple method suggested, calculating the capacitance value to self-excite the generator using the manufacturer data. A sequential systematic procedure of capacitance calculation of a 3. 7 k. W, 415 V, 7. 8 A, 1420 -rpm induction motor has been completed using its nameplate details. An attempt made to validate the proposed method. A proto type model of induction generator has been rig up in the laboratory using a separately excited D. C. motor coupled with an induction motor. Simulation studies of performance of SEIG have been completed using power system toolbox in Mat lab / Simulink software. 9/17/2020 VIT University, Vellore, Tamil. Nadu, India 632 014 2

CONCLUSION ü Simulation of SEIG completed using power system tools box in Mat lab / Simulink software. ü Rotor reference frame of induction motor in d-q axis considered for motor model. Initial current in the stator winding of SEIG taken as 0. 28 ampere and slip is 3% arbitrarily. ü Time required to build up the rated voltage is 1 second. The simulated results show 253 V with charging current of the capacitor is 2. 129 A with a frequency of 50 Hz. ü The proposed method is a simple and easy to calculate the capacitor require selfexciting the induction motor working as a generator and the grid connected induction generator. ü The capacitor connected across the grid connected capacitor to reduce the burden of the grid to supplies the leading VAR to the generators. ü The leading VAR required by the grid connected generator varies with vary the wind velocities. 9/17/2020 VIT University, Vellore, Tamil.
