设计并制作如图1所示的光伏发电并网系统。图中，采用交流调压器和单相不控整流电路来模拟光伏电池组件；并网逆变器的输出经交流调压器、变压器并入电网。-Design and production as shown in Figure 1 and the photovoltaic power generation system. Map, using the exchange and single-phase voltage regulator does not control rectifier circuit component to simulate the photovoltaic cells　and net output by the inverter AC voltage regulator, transformer into the power grid.
