并网仿真
单相逆变并网电路的主电路与控制电路的 simulink 拓扑结构图,
主电路由直流源、 mosfet 全桥、 LC 无源滤波器、 负载 R1、 R2 组成, 其中 R1 为
恒定负载, R2 为仿真负载突变并入的。
控制电路为 SPWM 闭环调制, 通过检测输出端的电压有效值通过 PI 控制器反
馈回控制端使输出电压尽可能为一个优质的正弦波且有效值在 220V 左右, 频率
为 50Hz, 根据相关准则输出电压波形 THD 应在 5%以内。(The Simulink topology of the main circuit and the control circuit of the single-phase inverter grid connected circuit,
The main circuit is composed of DC source, MOSFET full bridge, LC passive filter, load R1 and R2, wherein R1 is
The constant load, R2, is incorporated into the simulation load mutation.
The control circuit is SPWM closed loop modulation, and the effective value of the output voltage is detected through the PI controller
The feed back control makes the output voltage as high as possible a sine wave, and the effective value is about 220V, frequency
For 50Hz, the output voltage waveform THD shall be within 5%, according to the relevant guidelines.)

MT2D正演
1. 运行MT2DMODEL.m构建正演模型
2. 运行TMmodel.m和TEmodel.m正演计算,计算结果自动保存
3. 程序进行了优化,并将BICGSTAB(稳定双共轭梯度法)用于求解线性方程组,求解效率提高,一般情况下正演计算仅需1~2秒">
