摘　　要：通过对三相四线制供电系统的特点和非线性负载电流谐波污染分析,提出了可同时补偿电压跌落、谐波电流的负载端低压综合电能质量补偿方法,并设计了对应的混合型低压电能质量综合补偿器。实验和仿真结果表明,该补偿方法和混合型低压电能质量综合补偿器能有效地解决非线性负载形成的谐波和无功电流对电网供电质量的影响,有一定的发展前景和实用价值。Based on analysis of the features of three-phase four-line power supply system and nonliear load current harmonic pollution, compensation method of simultaneously compensating voltage sag and synthetic power quality of load low-voltage of harmonic current was proposed, and corresonding hybrid unified power quality compensator（UPQC） was also designed. The results show that this compensation method and UPQC can eliminate the effect by nonliear load, harmonie and reactive current on the quality of power network effectively, with some development prospect and practical value.
