摘要
简述了太阳能光伏发电系统的组成部分,分别搭建了光伏组件、DC-AC逆变桥、带锁相环的SPWM控制器、MPPT控制算法、电压前馈控制等子模块的Matlab仿真模型,着重分析了光伏电池工程建模方法和电压前馈控制方法的基本原理,专为此系统设计了用户界面Matlab/GUI,可查看任意组件的I-V特性曲线,仿真不同MPPT算法的效果并可调试PID的参数,保存系统仿真的波形图片和相关参数信息。
The paper firstly outlines the composition of solar energy PV power generation system, and constructs the Matlab simulation model for its sub-modules, including PV modules, DC-AC inverter bridge, SPWM controller with PLL, MPPT control algorithm, and voltage feedforward control, etc. Emphatically, the analysis is conducted on the modeling method for PV cell projects, as well as the fundamental principles of voltage feedforward control. Matlab/ GUI（ Graphical User Interface） user interface is designed for the system in order to check the I-V characteristic curves of any components, simulate the effects of different MPPT algorithms, debug PID parameters, and save the system simulation wave pictures and relevant parameter data.
