摘　　要：针对传统电压暂降治理方案多采用交流供电技术,存在转换效率低、切换速度慢等问题,从变频器的交直交结构特性出发,提出一种基于交直流混合供电的光储一体化电压暂降治理系统。该系统优先消纳光伏发电,市电作为补充电源,蓄电池作为后备电源,实现电压暂降治理的同时,还提高了系统的运行经济性。试验结果表明,在交流发生电压暂降的情况下,变频器连续不间断运行。In view of the traditional voltage sag control schemes that mostly use AC power supply technology,there are problems such as low conversion efficiency and slow switching time.Considering the AC-DC-AC structural characteristics of the inverter,a solar-storage integrated voltage sag management system based on AC-DC hybrid power supply is proposed.The system preferentially consumes photovoltaic power generation,commercial power is used as supplementary power supply,and battery is used as backup power supply,which not only realizes voltage sag control,but also improves the operating economy of the system.The test results show that the inverter runs continuously and uninterrupted under the condition of AC voltage sag.
