摘要
研究了3 kW单相光伏发电并网系统的逆变器滞环电流跟踪控制的控制方法.根据滞环电流跟踪控制的原理,利用MATLAB/SMULINK,建立光伏发电并网系统的控制模型.通过调整系统参数对并网系统进行仿真,得到并网电流和电网电压波形,使得输出功率因数近似为1,并对波形总谐波畸变率进行了分析,使其满足设计要求.最后,对单相光伏并网逆变器的滞环电流跟踪控制系统进行相关实验测试,所测得的实验数据与仿真结果基本符合.
The method of inverter control in 3kW single photovoltaic（PV） grid-connected generation system was studied.A model was created by MATLAB/SIMULINK on the principle of hysteresis-band current tracking control.After the adjustment of the system parameters and the system simulation,the grind-connected voltages and currents were giv-en,in which the power factor is approximate to 1.Meanwhile,the total harmonic distortion（THD） was analyzed.The correlative experiments proved that the experiment data were basically accorded with simulating results.
