The Design of Wind Power Converter Based on LCL Filter

Article Preview

Abstract:

As to the output current of grid inverter in high-power wind power generation system contains large current harmonic, the solution is to introduce the LCL filter to replace the typical inductance filter in grid inverter, which brings instability to the system, thus the control strategy is to use the grid inverter current indirect control combined with the grid voltage feed forward compensation. A 15KW wind power simulation platform is constructed. The experimental results show that the grid converter can run stably, and also have a better dynamic and static performance.
