摘要
电能质量事故大多是由电压跌落和电压瞬时中断引起的,为此对常用的电能质量问题解决方案的优缺点进行了比较,介绍了一种新型动态电压跌落修正器的拓扑结构、工作原理和目前的研究状况,指出了用动态电压跌落修正器解决低压领域电能质量问题是今后的发展趋势。动态电压跌落修正器无需串联变压器、没有电池、没有旋转飞轮,具有成本低廉、尺寸紧凑、重量轻、低维护、高效率等优势,对其进行研制和使用可取得巨大的经济和社会效益。
Power quality accidents are mostly caused by sag and transient interruption of voltage. In this paper, the advantages and disadvantages of the commonly used solutions to power quality problems are compared, and the topology, principle and current research situation of a novel dynamic sag corrector （DySC） are introduced. It is pointed out that the use of DySC for low-voltage power quality field is the future development trend. DySC dispenses with the series transformer, batteries and the rotating flywheel, characterized by low cost, compact size, light weight, low maintenance, high efficiency, etc. The development and use of DySC can bring tremendous economic and social benefits.
