ADSIG as Gen-Former providing three port network for soft coupling of distribution feeders in addition to wind energy harvesting

Abstract With increase in the Electric Vehicle (EV) load the coupling of feeder in the distribution has become essential. The paper prescribes the use of multiple Asymmetrical Dual Stator Induction Generator (ADSIG) acting as ‘Gen-Former’ to draw out coupling of feeders for bidirectional power transfer in addition to energy harvesting from the feed on its rotor from wind energy source. The paper presents an analysis of soft coupling for two feeders by providing route for power to flow from one power feeder to other power feeder region in addition to harvesting power from wind energy turbine. Asymmetrical Dual Stator Induction Generator (ADSIG) is modeled and analyzed for enacting as soft coupler for power transaction between two feeders together with wind energy harnessing. An experimental study is also done on a scaled down 3.75 kW developed prototype in the laboratory. The performance of the proposed system is analyzed and results show effective coupling between the feeders with power injection and effective power distribution by ADSIG under perturbing load conditions on either of the connected feeders.
