摘要
根据单相两级式隔离型光伏并网发电系统,设计出前级BOOST升压电路以及后级逆变电路,并分析了其系统控制,计算了BOOST电路以及低通滤波的元器件参数,搭建了MATLAB/Simulink仿真电路,经仿真实验,证明该两级式隔离型光伏并网发电系统输出电流波形失真度小,频率相位特性满足并网要求。
According to the single phase two stages of isolated photovoltaic grid connected power generation system, this paper designed the preceding stage BOOST circuit and the later stage inverter topology circuit, analyzed the system control, calculated the BOOST circuit and low- pass filter components parameters and built the Simulink simulation circuit in MATLAB. The simulation experiments prove that the two-stage isolated photovoltaic grid connected power generation system output waveform distortion is small. The system meets the requirements of grid connected frequency phase characteristics.
