摘　　要：为提升牵引供电网的供电品质并取消变电所的电分相,文章提出一种基于对称补偿的新型同相供电系统。首先介绍了基于三端口四象限变流器的新型同相供电系统的拓扑结构及工作原理,然后针对系统实现负序治理、谐波和无功综合补偿等目标,提出基于单相系统dq变换的三端口四象限变流器协同控制策略;最后根据实测负荷数据在Matlab/Simulink中搭建系统仿真模型,验证所提系统的可行性及有效性。In order to improve the quality of traction power supply network and cancel the phase separation of substation, a new type of in-phase power supply system based on symmetrical compensation was proposed. Firstly, the topology and working principle of a new type of in-phase power supply system based on three-port four-quadrant converter were introduced. Then, aiming at the goal of negative sequence control, harmonic and reactive power compensation, a coordinated control strategy of three-port four-quadrant converter based on dq transform of single-phase system was proposed. Finally, according to the measured load data, the system simulation model was built in Matlab/Simulink, the feasibility and validity of the proposed system were verified.
