【 摘 要 】

In the research data about power quality, it is shown that voltage sag is the worst power quality problem, which can bring the most losses in various power quality problems. Dynamic voltage restorer (DVR) is the most effective solution to suppress the voltage sag. The compensation effect of DVR can be affected by the compensation strategy. Based on the analysis of existing compensation strategy, the optimized compensation strategy of load voltage is proposed in this paper. The simulation results show that the optimized compensation strategy can give attention to both the capacity of DVR and the compensation effect of the load side voltage.
