摘　　要：针对电压暂降问题,利用动态电压恢复器(DVR)从超级电容器蓄电池混合储能装置汲取电能补偿负载电压。介绍基于有源式混合储能系统的动态电压恢复器的等效电路,建立了蓄电池电容器并联的数学模型和控制系统,提高整套DVR的工作特性与经济性能比。对有源式混合储能系统用于DVR进行仿真分析,结果表明对于持续时间较长的电压暂降,有源式混合储能系统能有效维持敏感负荷的电压恒定。To solve the problem of voltage sag,Dynamic Voltage Restorer（DVR） is used to compensate load voltage instantly based on active hybrid energy storage system,and its equivalent circuit is presented.Both the mathematical model and the control system of the ultracapacitor/battery hybrid system are set up,which improves whole working characteristic and economy of DVR.Simulation and analysis on DVR with active hybrid energy storage system are carried out,and the results show that this active hybrid energy storage system can effectively maintain the voltage level of sensitive load as to long-duration power interrupts and frequent voltage sag.
