摘　　要：电压暂降是发生概率最高的电能质量问题,动态电压恢复器(DVR)是解决电压暂降最直接有效的方法之一。DVR装置拓扑、电压暂降检测方法和补偿策略等得到了广泛研究,而试验方法却鲜有提及。在此分析了DVR装置拓扑结构,指出针对配电系统DVR适用拓扑——无串联变压器三单相桥DVR,提出了一种DVR装置低成本的全工况模拟试验方法,通过仿真和试验测试,验证了此试验方法的有效性和实用性。Voltage sag is a power quality issue of highest probability, and installation of dynamic voltage restorer（DVR） is one of the most effective and direct methods to solve this problem.Ahhough wide research has been carried out on the topologies, detection methods and compensation algorithms of DVR, the experimental method is seldom discussed. Based on analysis of the DVR topologies, a full condition simulation experimental method of low cost is proposed for the topology three single-phase bridges without series transformer,which is applied into the distribution system DVR.In the end,its validity and availability are testified by the simulation and experiment.
