摘　　要：介绍了一种基于统一电能质量调节器(UPQC)的电气化铁路同相供电方案,通过对UPQC的主电路结构、功能和控制方法的详细分析,指出了该控制器相对于现有其他方案的优点,通过仿真结果证明,基于UPQC的同相供电系统能解决电气化铁路存在的三相不平衡,电压波动,谐波污染,功率因数低等问题。Introduce a scheme of cophase power supply system for electrified railways based on Unified Power Quality Controller (UPQC). By systematically analyzing the main circle configuration, functions and control strategy of UPQC, the advantages of UPQC over other controllers are pointed out. The result of the simulation proves that the cophase power supply system based on UPQC can deal with some problems of electrified railway traction substations, such as three phase unbalanced voltage, voltage fluctuation, harmonic pollution and low power factor.
