研究了单相光伏系统在Matlab/Simulink下的建模与仿真。基于状态空间平均法建立了单相电压型PWM逆变器的数学模型，提出了增加直流侧电压控制环的双环控制策略，构建了单相光伏系统的Simulink模型，并进行了特性仿真。仿真结果表明，基于该控制策略的光伏系统动态响应快，输出电压总谐波畸变率低。

The modeling and simulation on Matlab/Simulink of single-phase photovoltaic ( PV) system is studied .The math-ematical model of single-phase voltage PWM inverter is set up based on state -space average method .The dual-loop con-trol strategy with the dc-link voltage control loop is proposed .And the single-phase PV system is modeled and the simula-tion of performances is carried out .The simulation results verify that the inverter with the proposed control strategy has a rapid dynamic response and a low total harmonic distortion ( THD) of the output voltage .
