哈大铁路客运专线牵引电力合建变电所优化设计

Optimized Design of Combined Substation for Power & Traction on Harbin-Dalian Passenger Dedicated Line

由于外部10 kV电源引入困难等原因,铁路牵引变电所往往需要与电力变电所合建,相比于普通牵引变电所,合建变电所由于需要挂接动力变压器,因而接线复杂、设备多,同时占用土地资源很大。结合哈大铁路客运专线新大连牵引电力合建变电所的设计实践,针对影响合建变电所的关键问题进行探讨,提出了合建变电所优化方案。

Because of the difficulties to inlet outside 10 kV power suppy,the railway traction power substation has to be combined with power station.Compared with common traction power substation,this combined substation requires the connection with power transformer,which is characterized by complicated wiring,device of great quantity,and big coverage of land.This paper discusses the key problems concerning establishment of combined substation,puts forward the optimized program in view of the experiences in the designing of the combined Dalian substation on Harbin-Dalian Passenger Dedicated Line.
