Design and construction of model battery charging control for stand-alone self-excited induction generator

Abstract

In this paper, design and construction of model battery charging control for stand-alone wind driven self-excited induction generator SEIG) is present. Apart from an energy transfer function from wind turbine (WT) with stand-alone SEIG, the proposed model battery charging control can also be an active power in linear loads with stand-alone for a three-phase four wire system. Initially, mathematical modeling of the wind turbine with stand-alone SEIG is given. The simulation based on mathematical equations obtained from the model provides electrical characteristics of the wind turbine source that which will be use as the battery charging control input of the inverter. Secondly, the main system has been virtually create in order to actualize the conversion from DC to AC and the main power circuit employs insulated gate bipolar transistors (IGBTs) formed in a three-phase full bridge. Thirdly, the control circuit is discuss and has been design and the control method used is voltage control with microcontroller for stand-alone linear loads that is simple. Finally, the obtained results are discusses in order to verify the correct operation as the system is designed.
