Research of Three Phase Grid-Connected Inverter Based on Fuzzy Logic Controller

本文对三相并网逆变器进行了阐述。在分布式并网发电系统中,三相并网逆变器是最为关键的部件之一。三相并网逆变器的性能主要取决于电流控制器的性能。通过对三相电压逆变器进行系统建模,经过abc三相静止坐标系下数学建模,引入dqo变换,使三相交流物理量转换为两相直流物理量。本文主要在MATLAB/SIMULINK环境中对基于模糊逻辑控制器的电流控制器进行了仿真研究。

In this paper,Elaburated the three phase grid-connected inverter,in the system of distributed grid-connected generate electricity, the three phase grid-connected inverter is one of the most important component. the three phase grid-connected inverter’s capability is decided by the electric current,get cross the system modling to the three phase grid-connected inverter.Mathematics modeling by the abc three phase quiescency reference frame,import dqo transform,make the three phase alternating current physics quantity conversionthe two phase.This paper mostly descric current based on fuzzy logic controler in the MATLAB/SIMULINK environment.
