基于PSIM的光伏发电并网系统仿真建模研究

Modeling and simulation of photovoltaic grid-connected system based on PSIM

对单相光伏发电并网系统进行仿真建模研究,在PSIM仿真环境下建立光伏直流升压模块、逆变器模块,采用外扩DLL模块,用C语言编程进行MPPT控制。通过对各模块以及整体进行仿真研究,验证各部分输出特性,能实现安全并网,对光伏发电并网系统研究具有一定的参考价值。

Simulation modeling on single-phase photovoltaic gridconnected power system. To establish the photovoltaic DC boost module,inverter module in the PSIM simulation environment,using the DLL expansion module,to exercise MPPT control with the C language programming. Through the simulation of each module and the overall,verifying the part of output characteristics can achieve safety grid,which has the certain reference value to the study of photovoltaic gridconnected system.
