This paper gives systematically study on grid-side converter with LCL filter for doubly-fed induction generator in wind power. This paper adopts the parameters of the PI-based controller that is already used for the L-filter-based active rectifier. On the basis of model in the dq coordinate system, the paper proposes a double-closed-loop control strategy. Then the simulation model of PWM rectifier is established in the MATLAB/SIMULINK environment. According to the articles theory imitation of the real system design with good dynamic and static performance.

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.
