摘要
电压闪变是供电系统主要的电能质量污染之一,国标GB12326-2000规定了闪变的限值和测试方法。已有的研究主要集中在电压闪变值的检测和计算等方面,而闪变干扰源的定位则是电能质量分析中的新课题。由于对干扰负荷的运行特性、闪变传播和危害评估缺乏深入研究,目前尚没有满足工程需要的干扰源定位方法。为此,综述了目前闪变干扰源检测的研究现状,探讨了闪变源定位研究的不同思路及其可行性,提出了闪变干扰源定位研究要解决的根本问题和所需的关键技术。
Voltage flicker is a common interference in distribution system. The limitation and detection method are proposed in GB 12326-2000. In the process of flicker analysis, much work focused on studying the voltage wave, computing the flicker severity and developing the flickermeter. The location of flick-type interference source is an emergent problem in power quality domain. Because the research on operating character of flicker-type interference load has been neglected, there isn＇t any applicable method of locating interference source in engineering After summarizing the detection methods of interference source＇ several qualitative location methods and their feasibility are discussed. Finally, the technical base and key point of interference source location are included in this paper.
