摘　　要：电气化铁道牵引供电系统存在大量的负序、谐波、无功,以及电分相引起的列车速度和牵引力损失等问题,采用近年来提出的一种新型同相贯通牵引供电系统,可以消除负序,补偿无功和实现较小的谐波畸变率,可以从根本上解决电气化铁道所造成的电能质量问题,取消电分相环节,适应铁路高速化、重载化的时代趋势。本文讨论了几种主流控制策略在同相贯通供电系统中的应用,并进行了仿真验证。According to the problems of negative sequence,reactive,harmonic that caused by traction power supply system as well as excessive phase,a novel cophase continuous scheme has been proposed.The system can eliminate the negative equence.Compensate for reactive and achieving a smaller harmonic distortion that can fundamentally solve the electrified railway caused by power quality problems,as well as cancel phase electricity sectors to adapt to the railway high-speed,overloading of the trend of the times.Discussed several main power supply control strategy of the cophase continuous power supply system,and applied simulation approach to verify so.
