| 摘 要： | 提出一种基于单周期控制超级电容器储能的单相并联型辅助电源装置.该电源装置在系统正常运行条件下具有并联型有源滤波器的滤波功能及动态无功补偿功能.当负荷由重载突变为轻载,甚至空载时,它能快速吸收突减的有功功率,当系统发生大的波动或短时供电中断时,它可向负载短时提供全部功率.实验研究表明,该装置能有效改善负荷品质,提高电能质量,增强负荷供电的可靠性.

| Abstract: | A novel auxiliary power supply is proposed in this paper.This converter coupled with super capacitor energy storage system and is controlled by one-cycle control scheme.It can act as APF,moreover,it is able to compensate rapid changing real power at fluctuating load to keep mains side outputting unit power factor and constant power.Also,it can support customer voltage for a short term during system outage.Experiment has been carried out to verify the construction and control strategy of this device for load quality improvement. |
