摘　　要：为了解决高速铁路牵引供电系统不平衡现象,对电气化铁路功率补偿装置进行研究并进行了补偿实验。采用级联型换流电路以及"背靠背"方式作为27.5 kV电压等级电气化铁路的综合补偿及谐波抑制拓扑结构,研究了适用于该结构的负序、谐波及无功快速检测方法及控制方法,并开发出一套铁路综合补偿系统装置。仿真及试验表明该装置能够有效实现牵引供电臂之间功率流动以及补偿等控制目标。A set of power compensation system was developed to eliminate power unbalances caused by electrified railway traction network. The cascaded and＂back to back＂prototype structure for railway unified power quality compensator（RUPQC）at 27.5 kV level has been built and its control method to detect and compensate the negative voltage,harmonics and reactive power in real time was also proposed. The simulation and experiments results show that the RUPQC system can effectively control and compensates the power flow between two AT traction power supply arms.
