【摘要】 动态电压恢复器(Dynamic Voltage Restorer,DVR)的能量提取与控制一直是研究的热点问题。提出并研究了基于VSC型高频整流电路的动态电压恢复器的能量提取方式;讨论了它的3种工作模式及控制策略,并针对系统三相对称、单相电压暂降及直流电压泵升条件下高频整流器的控制进行了仿真研究。仿真结果验证了该控制策略及其算法的正确性和有效性。更多还原

【Abstract】 Energy extraction and control of Dynamic Voltage Restorer (DVR) have been warmly discussed.This paper presents and studies high frequency reversible rectifier based energy extraction of DVR,researches on three operating modes of rectifier and three conditions of its control under system balance,single phase voltage sag,regeneration based on simulation.Results verified the correction and validity of presented control strategy and algorithm.更多还原
