Battery Charging Using Doubly Fed Induction Generator Connected to Variable Speed Wind Turbine

Wind energy, one of the renewable energy sources can be used as an alternate fuel. The main objective of this paper is to make the system with a variable speed wind turbine using DFIG to supply the local loads. The proposed system using DFIG is modelled and simulated in MATLAB. The slip power from the DFIG in its super synchronous mode of operation can be used for battery charging through back to back connected converters. Here machine side converter acts as the rectifier and the battery side converter as inverter. The simulations analysis for battery charging is done here using MATLAB Simulink model.
