城市轨道交通静止无功发生器设置

Analysis on Setting Static Var Generator(SVG)

主要阐述城市轨道交通静止无功发生器(SVG)设置的必要性和原理。在运营初期、近期的用电负荷较小,功率因数较低;随着用电负荷的增大,功率因数能满足要求。结合主变电所各种运行方式,合理设置SVG的补偿容量,使得功率因数满足供电部门的要求,既有利于提高供电质量、减少电费支出,又有利于整个供电系统的稳定运行。

This article describes the necessity of setting static var generators（SVG） in urban rail transit and introduces their working principles.During the early stage and recent operation,the electric load is small and the power factor is low,while with the load increasing,the power factor can meet all requirements.This article considers all kinds of operating modes of main power substation and proposes to set the reasonable compensation capability of the SVG to make power factor satisfying the requirements of power supply sections,which will not only improve the quality of power supply and reduce electric charge,but also guarantee the stable operation of power supply system.
