基于准Z源逆变器的光伏发电系统的仿真研究

Simulation Research of a Photovoltaic Power System Based on the Quasi Z-Source Inverter

准Z源逆变器是一种在光伏发电系统中有应用前景的新型逆变器.本文用Matlab建立系统的仿真模型,把现有建筑的一套屋顶光伏发电系统改造成基于准Z源逆变器的光伏发电系统,该系统包括光伏阵列模块、主电路模块和控制模块.静态和动态仿真结果证明了所建模型的正确性.

Quasi Z-source inverter, a novel inverter, has promising application prospect in photovoltaic power system. This paper creates a Matlab simulation model, which transforms the photovoltaic power system on the roof of an existing building into one based on the quasi Z-source inverter. The simulation model consists of photovoltaic arrays model, main circuits model and control model. Results from static and dynamic simulation verify the validity of the model.
