摘要结合电气化铁路外部电源供电方式及牵引供电系统供电方式,提出一种牵引变电所群贯通供电系统,并研究相关关键技术方案。首先,根据负序补偿方式将牵引变电所群贯通供电方案分为集中式补偿和分布式补偿两类,其中,集中式补偿方案分为N模式和N+1模式。其次,针对无功型负序补偿方式,将其分为二端口和三端口补偿模式,以YNd11联结变压器为例阐述负序补偿的基本原理,并介绍集中式补偿方案的潮流控制系统。然后,介绍贯通牵引网分段保护与状态辨识技术方案。最后,探讨外部电源方案,并以某线路实测数据为例,研究树形结构下的均衡电流情况,结果表明,构成树形结构的供电方式能够最大限度实现无均衡电流供电。

Abstract：Combined with the external power supply modes of electrified railway and the power supply modes of traction power supply system, the interconnected power supply system of traction substation group is proposed, and its key technical schemes are studied. Firstly, according to the methods of negative sequence compensation, the interconnected power supply schemes of traction substation group are divided into centralized compensation and distributed compensation. Among them, the centralized compensation schemes are divided into N mode and N+1 mode. Secondly, the compensation modes are divided into two-port and three-port for the compensation methods of negative sequence with reactive power. Taking YNd11 connection transformer as an example, the basic principle of negative sequence compensation is illustrated, and the power flow control system of centralized compensation is introduced. Then, the technical scheme of section protection and state identification for interconnected traction network is introduced. Finally, the external power supply scheme is discussed. Taking the measured data of a certain line an example, the balanced current under the situation of tree structure is studied. The results show that the power supply mode of the structure of the tree structure can maximize the power supply without balanced current.

Key words： Traction substation group interconnected power supply negative sequence com- pensation static var generator (SVG) section protection and state identification
