Wind Generation System

In wind generation system, the power converter efficiency is one of the key factors for the performance of the system. In those systems, DC/DC Buck converter is widely used for high power system. Considering the converter’s cost and efficiency, this paper mainly focuses on the design of an improved topology Buck converter adopted for high power standalone wind generation system. The designed converter uses multi-MOSFETs in parallel instead of the IGBTs, in order to increase the conductive current as well as the converter switch frequency. From the experimental tests results, the maximum efficiency of the designed 2 kW Buck converter is up to 96% based on maximum power point tracking (MPPT) method.

Wind Generation System

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.
