摘　　要：定量分析计算电网电压暂降时DVR逆变单元与电网的功率交换情况,详细研究逆变单元在各种补偿策略下的输出电压和有功功率与故障前后电网电压、负载电压和参考相量的具体关系,并根据具体关系总结出5种补偿方法,通过Matlab平台对各种补偿方法进行仿真研究,最后根据不同的补偿方式进行单相DVR检测方法研究。This paper quantitatively analyzed and calculated the power exchange between DVR inverter unit and grid with voltage sagged, focusing on the specific relationships among the output voltage, active power of the inverter module under different compensation strategies and grid voltage, load voltage and reference phase before and after the fault, and summarized five kinds of compensation methods. Simulation of these compensation methods were conducted through the Matlab platform, and finally were studied based on different means of single-phase DVR detection.
