摘要
通过对三相四线制供电系统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和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(UPQC)。实验和仿真表明:此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,是集中式电能综合补偿的必要补充,有一定的发展前景和实用价值。
To analyze the features of three-phase four-line power supply system and nonlinear load current harmonic pollution, com- pensation method of simultaneously compensating voltage sag and synthetic power quality of load low-voltage of harmonic current is proposed, and corresonding hybrid unified power quality compensators（UPQC）are also designed. The results show that this com-pensation method and UPQC can elimiate the effect caused by nonliear loads, harmonic and reactive current on the quality of power network effectively, which is a necessary complement for centralized power synthetic compensation and has some development pros- pect and practical value.
