研究三相单级光伏并网系统,建立并网逆变器在同步旋转d-q坐标系下的数学模型,提出一种新型的滑模变结构矢量控制方法。将并网电流分解为有功电流和无功电流,控制无功电流分量为零,实现单位功率因数并网;控制有功电流分量为MPPT算法给定的参考值,实现最大输出功率跟踪。组建实验样机,进行稳态和动态性能测试,实验结果表明所提出系统的可行性和控制策略的有效性。

The three-phase on-grid PV power generation system is studied, and mathematical model of three-phase on-grid inverter was established in synchronous rotating reference frame （d-q）. A novel sliding mode variable structure vector control methods is put forward, which made the grid current into the active current and the reactive current. Unit power factor is achieved by controlling the reactive current component to be zero; and PV maximum power output was realized by controlling the active current component to be the reference value given by MP...
