通过理论分析，提出基于LCL滤波的并联型有源电力滤波器(SAPF)双环控制系统的设计方法. 结合具体实例，从系统稳定性方面考虑，提出LCL滤波器电网侧电感和逆变器侧电感的分配方式、阻尼电阻和比例增益的选择方法. Matlab/Simulink仿真验证了所提参数设计方法的有效性.
Through theoretical analysis，a design method for LCL-filter-based double-loop control system of shunt active power filter (SAPF) is proposed in this paper. Considering stability of the system，the distribution of inductance between the grid side and inverter side，the selection of damping resistance and proportional gain are put forward combined with a specific example. The simulation with Matlab/Simulink verified the correctness and effectiveness of the proposed design method
