摘要
分析了三相光伏并网逆变器无功输出控制的工作原理,提出了同步旋转坐标系下采用PI调节器的逆变器功率因数控制设计方案。在MATLAB/SIMULINK环境下进行了系统建模与仿真,并在尚义安装的150kVA功率因数可调并网逆变器上进行了现场试验,实际运行结果证明了本文提出的功率因数可调逆变器设计方案的可行性。
An adjustable power factor control scheme using Proportional Integral （PI） regulator in synchronous rotating reference frame was proposed and the passive power output control was analysis as well.A simulation model for the simulating research was build up in MATLAB/SIMULINK.Based on the simulation results,a 150kVA three phase grid-connected inverter prototype was development to verify the effectiveness of adjustable power factor control scheme.
