摘　　要：本文主要介绍了针对电网模拟器的系统进行设计,采用10kV高压充电电阻串联至电网模拟器的主回路中,并接旁路接触器。当电网模拟器充电完成后,用接触器迅速旁路充电电阻。电网电压经过二次侧多重化的隔离变压器移相降压后向功率单元供电,功率单元为三相输入、单相输出的交-直-交PWM电源型逆变器结构。将相邻功率单元的输出端串接起来,形成级联结构,实现变压变频的高压直接输出。This paper mainly introduces the design of the system for the grid simulator,using 1okV high voltage charging resistance in series to the main circuit of the grid simulator,and connecting the bypass vacuum contactor.When the grid simulator is charged,the contactor.The power grid voltage is power to the power unit after the isolation transformer on the secondary side.The power unit is a cross-direct-direct-PwM power inverter structure with three-phase input and single-phase output.The output ends of adjacent power units are connected to form a cascade structure to realize the direct output of variable voltage frequency conversion.
