摘　　要：阐述了铁路电力系统的自闭和贯通电力线路为铁路沿线自动闭塞信号及车站负荷等提供电源。介绍了一种节能型动态无功补偿系统,根据用电负荷需要补偿的容量,改变有载分接开关的接头,从而改变并联电抗器电压,进而实现自闭贯通线电压、无功的综合自动调整,从而实现提高供电电能质量、线路无功平衡的目标。Self- blocking and run- through power lines in railway electric system provide power supply for railway control signals and railway stations. This paper introduced an energy saving- dynamic reactive power compensation system. According to compensation capacity that power load requires, this system employs on- load tap changer to change the voltage of shunt reactor so as to realize automatic adjustment for reactive power and self- blocking lines voltage. In this way, power quality can be improved and reactive power balance can be realized.
