本模型采用矢量控制与SVPWM相结合的方法，应用在低压微电网中。直流源电压为600V，逆变器输出电压为380V，可实现稳定功率输出。模型对网侧控制策略中每一模块尽量做出了说明，方便初学者更快理解三相逆变器控制策略的实现方法，运行效果非常好。(This model adopts the method of combining vector control with SVPWM, which is applied in low voltage microgrid. The DC source voltage is 600V, and the inverter output voltage is 380V, which can achieve stable power output. Each module is explained as far as possible in the network side control strategy. It is convenient for beginners to understand the realization method of the three-phase inverter control strategy faster, and the operation effect is very good.)
