高新技术产业的发展对供应电能的质量提出了新的要求。电能质量的研究与控制问题引起了人们的关注。针对这一问题,近年来提出了一些新的概念和新型DFACTS装置。其中动态电压恢复器(DVR—Dynamic Voltage Restorer)则是一种控制电压的比较好的解决方法。本文阐述了DVR的优越性,详细说明了DVR使用的四种补偿方式,并给出了仿真波形。仿真结果表明四种方式各有特点,在应用时可根据实际情况加以选择。
【英文摘要】
Developed technology requires high power quality. So the studies and problems of power quality have been emphasized. Recently many of the new ideas and new DFACTS have occured to solve these problems .Dynamic Voltage Restorer (DVR) is a better solving method to control voltage. The advantages of DVR are expounded in this paper. Four compensating modes are put across in detail. Emulation results and waveforms manifestated their characteristics. So they can be selected according to facts.
