On the study of wind energy conversion system applied to battery charching using multiblade turbines

This paper presents control system design of a small size wind generation system for battery charging using a multiblade wind turbine. A boost converter is used to regulate the battery bank voltage. Thus, an MPPT algorithm can be implemented as well as the reduction of the mechanical speed can be performed in order to avoid a battery overcharging or overcurrent. The system overview and modeling are presented including characteristics of wind turbine, generator, batteries, power converter, control system, and supervisory system. A simulation of the system is performed using MATLAB/SIMULINK software to obtain the MPPT points. Experimental results for the complete system are also presented.
