摘要
针对光伏阵列的特点,提出了基于最大功率点跟踪(MPPT)的光伏阵列并网发电方案,采用电网电压前馈和电流跟踪技术,建立了相关的控制模型,实现了网侧电流正弦化且为单位功率因数,实验结果证明了方案的正确性。
A photovoltaic grid-connected inverter with maximum power point tracking (MPPT) is proposed. The control model of system is founded by the technology of grid voltage feed forward and current tracking. In this system, sine wave grid connected current and unity power factor are realized. The experiment proves the control concept described in this paper.
