| Summary: | This paper presents an energetic comparison between two control strategies of
a small size wind generation system for battery charging. The output voltage
of the direct drive PMSG is connected to the battery through a switch mode
rectifier. A DC-DC boost converter is used to regulate the battery bank
current in order to achieve maximum power from the wind. A maximum
powertracking algorithm calculates the current command that corresponds to
maximum power output of the turbine. The DC-DC converter uses this current to
calculate the duty cycle witch is necessary to control the pulse width
modulated (PWM) active switching device (IGPT). 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. |
