摘　　要：LCL型滤波器能够用较低的电感量滤除较多的高频谐波。基于此建立了LCL型并网逆变系统的数学模型,提出了采用遗传算法来优化设计网侧LCL滤波器参数的方法。仿真结果表明,采用优化参数的滤波器具有良好的网侧谐波抑制能力,从而验证了该设计方法的可行性和优越性。LCL filter can achieve better filtering effect by smaller inductor values, based on it, the mathematical model of LCL type connected-grid inverter was constructed. This paper also proposed an optimized design method based on genetic algorithm for LCL filter. The sinmlation results indicate that the optimized filter has favorable ability of harmonic suppression, and it is significant for practical application and prove the feasibility and superiority of the design.
