Abstract

Dynamic Voltage Restorers (DVR) provide an advanced and economical solution for voltage sag/swell events. Such devices are used to protect sensitive loads on distribution electrical systems, placing it in series with sensitive loads. This paper presents a single-phase DVR performance under such events, able to compensate sags/swells in two cycles. A peak detector and the in-phase compensation method are used to get quick and accurate responses. The digital control system is implemented on the CompactRIO embedded system, and is programmed in LabVIEW software. The effectiveness of the proposed DVR system is verified and validated through simulations and experimental tests.

基于电力电子器件的瞬态电压补偿
动态电压恢复器(DVR)为电压骤降/膨胀事件提供了一种先进而经济的解决方案。这种装置用于保护配电系统上的敏感负载,将其与敏感负载串联起来。本文介绍了在这种情况下的单相DVR性能,能够在两个周期内补偿下降/膨胀。采用了峰值检测器和同相补偿方法,得到了快速准确的响应。数字控制系统在CompactRIO嵌入式系统上实现,并在LabVIEW软件中编程。通过仿真和实验验证了所提出的DVR系统的有效性。
