Research on Grid-Connected Inverter Based on Current Track Control in Wind Generation System

In wind generation system, the control of the grid connected inverter is most important in achieving the transformation and transmission of the power. The system is controlled by the feedback of the instantaneous current, and the synchronous signal of the grid voltage is used as the current track command of the inverter directly. The system uses the closed-loop control of the feedback grid current to get the unit power factor transmission. The control system model of grid connected inverter based on switch function is set up, and the simulation and experiment results show that the proposed control strategy can achieve a better quality of the current fed back to the grid and improve the stability and dynamical performance of the grid connected inverter.
