分析了城市轨道交通用电负荷的特点及主变电所无功补偿的意义，在现有三种无功补偿方案（电抗器固定补偿、SVC及SVG动态补偿）的基础上，结合轨道交通用电负荷的特点及目前低压配电系统、直流牵引系统新设备的采用，提出了两种新的无功补偿方案。%This paper analyzed the characteristics of the load of urban rail transit and the significance of the reactive power compensation for high voltage substation. Base on the existing three kinds of reactive power compensation scheme (fixed compensation of reactor, SVC and SVG), combining the characteristics of the load of urban rail transit and the new equipment used for DC traction system and low voltage power distribution system, two new reactive compensation schemes are put forward in this paper.
