摘要
针对单相电压型并网逆变系统,设计了电流内环、电压外环的双闭环控制系统,建立了内外环数学模型;运用MATLAB/Simulink建立了单相并网逆变系统仿真模型,对双闭环控制系统及滤波电路的性能进行了验证分析。结果表明,基于三角波载波的双闭环控制,具有较高的稳态精度和较快的动态响应。
As the single phase voltage source inverter,a kind of control strategy of double close loop control was designed,the matical models of inner and close loop were established, the simulation model of single phase voltage source grid-connected inverter system was established and the performance was tested based on MATLAB/ Simulink. The result proved that the inverter controlled by double close loop had good stability and dynamic response.
