System simulation of double-stage single-phase photovoltaic inverter based on Simulink
针对单相光伏并网系统,以两级式单相并网逆变器的主电路拓扑结构为核心,对其建立了数学模型,并在Matlab/Simulink环境下,搭建了5 kW单相并网逆变器的系统仿真模型。采用基于扰动观测的MPPT算法以及基于电网电压前馈的双闭环控制策略,对其特性进行了深入研究和仿真。并用Matlab语言将MPPT算法编写了函数,可以模拟光照变化,分别针对光照不变和光照变化两种情形进行了仿真分析。结果表明,其不但保证系统有较好的稳定性和快速的动态响应跟踪特性,…查看全部>>
For single-phase photovoltaic grid system, taking the circuit topology of double-stage single-phase grid inverter as a core, this paper establishes the mathematical model, and builds the simulation model of 5 kW single-phase grid inverter system in Matlab/Simulink environment. MPPT algorithm based on the observation of the disturbance voltage and double loop control strategy based on feedforward are adopted, whose properties are studied and simulated. With M…查看全部>>
