摘　　要：由于电气化铁道牵引供电系统结构和牵引负荷的特殊性,在负序、谐波、无功方面对电力系统可以造成很严重的影响。将一般形式的牵引变压器与综合潮流控制器(IPFC)相结合,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。以一列运行的机车为对象,进行仿真研究,结果验证了上述模型可以实现设计目标。Because of the particularity structure of the electric traction power supply system of electrified railway,negative sequence, harmonic, reactive can cause a very serious effect on electrical power system. By combining a common connected transformer with an integrated power flow controller（IPFC）. 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 locomotive as an example, the software simulation is carried out and results show that the model can eliminate the three-phase imbalance and can filter the harmonics and reactive currents.
