摘　　要：设计了一种三相电子负载模拟装置。该装置采用AC/DC/AC双PWM变流器为主电路结构,通过有功功率和无功功率的解耦控制,来模拟平衡的、不平衡的、稳态的、动态的阻性、容性、感性等各种各样的交流电子负载,同时能实现能量回馈,通过仿真验证了该装置设计方案的可行性和合理性。The paper presents the electronic AC load which can simulate various loads in three phase AC system. The load simulator has an AC/DC/AC dual-directional PWM inverter controlled by using positive and negative sequence dq synchronous frame, and can simulate changing load, unchanging load, unbalanced load, balanced load, resistive load, capacitive load and inductive load. In addition, the testing energy can be feedback to the utility grid. In this paper, simulation results demonstrate the effectiveness and feasibility of the proposed control strategy.
