摘　　要：对于LCL并网逆变器在谐波下的控制策略,本文利用组合反馈,精简了反馈变量的测量;采用比例谐振控制,使系统获得较优的稳态性能和抗干扰性能;利用电网电压前馈,使系统对电网谐波具有良好的抑制能力,文章详细说明了该控制策略的参数设计步骤。仿真结果表明,该方法可使逆变器获得了高质量的并网电流。In allusion to the resonance control strategy in grid-connected inverter with an LCL filter, the method of composite current feedback is adopted to streamline the measurements of feedback variables; proportional resonance （PR） control is put forward to enhance the stability of system and resistance against interference; and grid voltage feed-forward control is suggested to effectively compress the resonance caused by LCL filter. The effectiveness of the proposed control strategy is validated by detailed experiment parameters and the simulation.
