摘　　要：在城市轨道交通工程中供电系统的功率因数一直存在着调节复杂的情况。由于在城市轨道交通运营初期供电系统负载率较低,带电电缆产生的容性无功难以被吸收,从而造成系统功率因数偏低、无功功率损耗较大的现象;另一方面,由于城市轨道交通"夜间检修、白天运营"的特点,每天不同时段的负载性质不同,在固定的时间段,也存在着供电系统功率因数无法满足供电部门要求的情况。因此城市轨道交通供电系统中引入动态无功补偿装置(SVG)设计作为功率因数的调整方案,是非常有必要的。The power factor of power supply system in urban rail transit engineering is always complicated. Because of the low load rate of power supply system in the early stage of urban rail transit operation, the capacitive reactive power generated by live ca-ble is difficult to be absorbed, which leads to the phenomenon of low system power factor and large reactive power loss. On the oth-er hand, due to the characteristics of ＂maintenance at night, operation in daytime＂ of urban rail transit, the load nature of different periods of the day is different. In a fixed time period, there is also the situation where the power supply can not meet the require-ments of the power supply department. So it is very necessary to introduce Static Var Generator （ SVG） into the power supply system of urban rail transit as the adjustment solution to power factors.
