摘要

变频驱动器(vfd)是众所周知的谐波源。本文提出了这样一个驱动器被识别为闪烁源的情况。变频器由于是谐波源而引起电压闪变。互次谐波会与基频分量发生跳动，从而产生电压闪变。通过现场测量和仿真研究，阐述了变频器是如何引起电压闪变问题的，以及影响变频器闪变产生特性的各种因素。本文可以作为一个有用的例子，指导需要解决电压闪变问题的人们。

A case study of flicker/interharmonic problems caused by a variable frequency drive

Variable frequency drives (VFDs) are well known harmonic sources. This paper presents a case where such a drive is identified as a flicker source as well. A VFD causes voltage flicker due to the fact that it is an interharmonic source. The interharmonics could beat with the fundamental frequency component, resulting the generation of voltage flicker. Through field measurements and simulation studies, this paper explains how a VFD causes voltage flicker problems and the various factors that have an impact on the flicker generation characteristics of a VFD. This paper can serve as a useful example to guide people who need to troubleshoot voltage flicker problems.
