摘要
电压跌落是目前电力系统中最严重的电能质量问题 ,采用动态电压恢复器 (DVR)向电力系统注入电压可以补偿电压跌落。在满足用户电力的同时 ,考虑到动态电压恢复器的电压注入能力和能量补偿能力 ,对DVR的几种电压补偿策略进行了分析和比较 ,并提出了一种新的补偿策略 ,最后采用仿真实验对分析结果进行了验证。
Voltage sag is one of the most important power quality problems challenging the power system,and voltage sags can be compensated for by dynamic voltage restorer injecting voltage into power system.Several voltage compensation strategies are examined,in terms of the energy storage device and the voltage injection constraint of dynamic voltage restorer,and the analyzing results are also validated by simulation studies.
