摘要
目前通信机房低压配电系统无功补偿普遍采用电容柜自动投切系统实现。近年来,这种无功补偿方案暴露出诸多弊端,也酿成不少事故。文中在对一起电容补偿柜烧毁事故进行技术分析的基础上,总结了利用电容器进行无功补偿的不足之处,分析了SVG(静态无功发生器)的基本原理及技术优势,提出了通信机房供电系统采用SVG作为无功补偿的新方案。
Capacitor ark auto-switching system is widely applied to compensate reactive power of low voltage distribution system in communication station at present.In recent years,this reactive power compensation method has exposed many shortcomings and has caused various accidents.Based on the technical analysis for a burning accident of capacitor compensation cabinet,this paper summarizes the disadvantages of capacitor compensation method,analyzes the basic principles and technical advantages of SVG（Static Var Generator）,and proposes a new method of reactive compensation with SVG.
