摘 要:
分析了影响并网逆变器输出电流波形质量的主要因素,建立了含变压器的三相并网逆变器输出电流的数学模型。在此基础上提出同步旋转坐标系下谐波扰动重复控制与基波电流PI(比例积分)控制相结合的三相并网逆变器系统控制方案。实验证明该方案能够有效抑制逆变器输出电流的谐波扰动、改善电流波形质量。[著者文摘]

Abstract:
Some factors affect the inverter's output current was analyzed. One control scheme was presented using the combination of a PI controller and repetitive controller tracking fundamental component and restraining harmonic disturbance. The experiment results showed that the scheme works well, and highly accurate steady output and less harmonic disturbance was obtained.[著者文摘]
