摘　　要：电气化铁道牵引供电系统存在的分相绝缘器,制约了高速重载铁路的发展。将V,v接线变压器与综合潮流控制器(IPFC)相结合,构造出的新型同相牵引供电系统。通过检测得到综合补偿电流并以此为参考,采用基于不定频滞环优化SVPWM电流控制方法,控制综合潮流控制器基本消除三相不平衡,并滤除谐波和无功。以一列满载运行的机车为对象,进行仿真研究,仿真结果验证了系统结构,检测方法以及控制方法是正确的,同相供电系统方案是可行的。The development of high-speed and heavy-loaded railway is restricted by the neutral section insulator of electric traction power supply system.A new cophase power supply system is proposed by combining a V,v connected transformer with an integrated power flow controller.According to the cophase comprehensive current detected,using the optimization method of SVPWM current controlling based on indetem inate frequency hysteresis, the controlling of an integrated power flow controller can eliminate the three-phase imbalance and can filter the harmonics and reactive currents.With a full-load locomotive as an example ,the software simulation is carried out and results show the correnctness of system topology,detection method and control method.The proposed system is proved to be feasible by the simulation.
