| Abstract: | The wind generation system has a diode rectifier, a boost DC/ DC converter and a single-phase inverter in parallel with the grid to enable grid-connected operation. The control strategy was developed for the systems. That is: PI control for boost DC/DC converter; deadbeat current control strategy for grid-connected inverter; and the context effect was analyzed. A 3.5kW grid connected inverter was designed. Experiment results prove that the method has good dynamic and static characteristics. |
