摘　　要：设计了一种基于并网逆变器的变频器电力电子可控负载,采用两相旋转坐标系中基于PI调节器的电流单闭环控制策略。提出了该可控负载的电路参数设计方法,包括启动电路的设计、变压器变比和逆变器输出线电压的设计。研究表明,该可控负载能提供可调的工作电流来模拟负载波动,并且可以模拟不同类型的负载特性,证明了在变频器测试系统中,采用并网逆变器负载作为可控模拟负载的方法是可行的。A controllable power electronic load for transducer based on grid-connected inverter was designed, with current closed-loop control strategy based on PI regulator in the two phase rotating reference frame. An approach for this controllable load was presented to design circuit parameters,including the startup circuit,ratio of transformer and output line voltage value of inverter. According to the research,the controllable load could provide adjustable work current to simulate the load fluctuations and various kinds of load characteristics. It is proved that the approach to build controllable analogous load based on grid-connected inverter is effective.
