摘　　要：能有效解决暂态电能质量中的电压跌落问题,而动态电压恢复器(DVR)的补偿策略决定了电压补偿的效果。介绍了DVR现有的补偿策略。通过计算分析,对其进行了优化。优化后的补偿策略兼顾了DVR的功率输出和补偿跌落电压的效果。仿真结果验证了该补偿策略能实现DVR的优化补偿。Dynamic voltage restorer （DVR） was an effective solution to compensate the voltage sag. The compensation effect of voltage was decided by the compensation method of DVR. Several current compensation strategies were introduced. By calculation and analysis, the optimal compensation strategy, which taked account of both power output of DVR and compensation effect of voltage sag, was put forward. The better performance of proposed compensation method is validated by the simulation studies.
