市域轨道交通牵引变电所三电源接线方案研究

由于易受到地形条件限制,市域轨道交通变电所所址位置选择通常难度较大。本文基于市域轨道交通传统交流牵引变电所接线方案,提出牵引变电所三电源接线设计原则及接线方案,并对牵引变电所三电源接线方式下各种运行方式进行具体说明,相关成果可为今后市域轨道交通牵引变电所供电系统设计提供参考。

The selection of the locations for substations of urban rail transit is very difficult since it is liable to be restricted by the terrain conditions.On the basis of the connection scheme of traditional AC traction substation of urban rail transit,the paper proposes the design principle and connection scheme of three power supply connection of traction substation,and specifies various operation modes under the triple power supply connection of traction substation.Relevant achievements can provide reference for design of power supply system for urban rail transit traction substation in the future.
