摘要
针对采用LCL滤波器三相光伏并网逆变器,首先进行理论分析并建立数学模型,其次提出一种极点配置与重复控制相结合的并网控制方案,最后通过实验验证理论分析的正确性以及控制策略的可行性。
The three-phase inverter with LCL filter was theoretically analyzed and the state-space mathematic model of the inverter was established in the paper. Through the analysis about pole-assigrtment control and repetitive control, a hybrid controller incorporating repetitive control and state feedback pole-assigrtment control based on single-phase inverter with LCL filter were designed, and the validity of the controller was proved by the experiment.
